I really appreciated that last bit; we hear a lot about Munro, but never really get the tour sort of speak. Even if they considered that a "commercial" the work and effort they put into showing this stuff off like they've never done before deserves some reward.
It's definitely a commercial. Monro has a platform. Part of having a small business like his is sales. If this helps bring businesses to him, then great. He's letting people know he's open to work on their projects. This makes him feel uncomfortable, and I get it. But I like that it makes him feel uncomfortable. It should. That is a sign of old school integrity right there.
Thing is, my grandma’s meatballs tend to make considerable noise vibration and harshness a few hours after consuming them, however you could power an internal combustion engine with what emerges.

To those of you who have asked about the golf ball. The material is E.A.R. from Aearo Technologies LLC (company now owned by 3M). earglobal.com/en/aircraft/
I've never understood why *the biggest enemy of a battery is cool not hot.* I've always thought while once used as motive power heat is what degrades efficiency of a battery and not an excessively *cool*(by temperature) battery. Having been a snowmobile rider in my past life I can speak with Authority on the value of *active cooling*(running a 2 stroke motor through snow) as creating an enormous benefit to engine efficiency in point of fact. And I think a *note* on energy efficiency is always worthy of discussing as the idea that a two stroke motor is *energy inefficient* relative to anything is plainly false. We use to drag race stock snowmobiles against tricked out motorcycles in Florida and blow them away all the time way back in the 1990s before everyone caught on to the obviousness as to why that was.
@@doolittlegeorgeI think he may have been referring to the cool as the biggest enemy in the context of efficiency as turning on the heater can draw almost 8kw on the Model 3.
@@doolittlegeorge The optimal temperature for most Li-Ion batteries is around 35C. Significantly higher temperatures may be dangerous, cells can get damaged. Anyone who knows chemistry, knows that most reactions slow down in lower temperatures, that's what happens to batteries too. A cold battery (approximately under 10C) loses some of the capacity AND is slowed down, meaning that it can't charge nor output energy as fast as at 35C. These problems will be solved with new battery formulas soon. PS: gas engines have nothing to do with efficiency. Most of them create more heat than rotation, except for those weird rotary engines from Mazda, which can reach 50% efficiency.
@@charanaa3023 Looked and bounced just like a normal minigolf ball. A solid plastic ball bounces minimally, that's why it's good for minigolf with obstacles and banks.
I was surprised that there was no comparison of the Y's sound deadening relative to the Model 3? There have been some anecdotal reports of the Y being quieter. Did you see any evidence to support that?
I think the comparison should be taken with a grain of salt. The Model 3 Munro analysed was a pretty early production model. So all comparisons are a current Model Y with an old Model 3. Model 3 got a lot of tweaks and upgrades since then. So one should not say "Model Y has this and Model 3 doesnt" or "this is different between the Y and the 3" just based on these videos. We dont know if the parts are also changed on current Model 3. Still nice to see what changed in these years.
@@DavidHRyall the downside of that decibel meter is that it only tells you about the loudest sound, it doesn't tell you anything about the sound in general, so whatever sound there is may be almost as loud but there's less different sounds to be heard. making it sound much quieter. also certain frequencies can be very annoying to (different) people as we're more sensitive to them. hope i'm making some sense here as its sometimes hard to put what i'm thinking into english
@@Derpy1969 The Ford Futura on which the Chuck Barris Batmobile is based also had a slanted radiator. How do I know? Because I talked to the owner of one while it was cooling down after overheating on the side of the road.
Tell us more about it :) Sandy talked about finite element analysis. Are they any other way to figure out the location where it would be more efficient?
@@Findalfen Big flat areas like the other person said. Sandy called it "drumming" because those large areas really move like a drum head. Basically you run analysis, find the hotspots, add damping and mass into that area (which is how you approximate these sound deadener's effect) and show what the difference.
@@bassrover5925 It takes a bit more, especially when talking mass production. One thing to keep in mind is that an even coating of that stuff is nearly useless. You then still have the exact same drum, it just takes a bit more energy to get it vibrating. Instead you want to capture the specific frequencies it resonates at and convert them into heat. You can see this nicely on the trunk where there are 2 triangles. Those cover a wide frequency spectrum, dampening the metal's vibrations at those frequencies.
When I was an auto mechanic in the mid 1960s One customer had a new car that would make a horrible drumming sound at unpredictable times. After spending untold hours looking for it we finally narrowed it down to spot on the firewall. We fixed it with one mighty swing of a large ball peen hammer. The resulting dent changed the resonant frequency of the panel and the problem went away.
best (first) 2 1/2 first minutes and introduction of a video ever since! I have laughed so much, thank you! :D Seriously, i want this golf ball to have some fun with people! :D Please get a bunch of those balls for us as giveaways - i am already smiling :)
You're Robin Hood. Your're leveling the playing field through knowledge, allowing the small guys to catch up with the big guys, by sharing everybody's secrets.
Other carmakers use those, sometimes called STUFFER BLOCKS. They block airborne noise moving between compartments. Other materials used are squishier, resembling pillow stuffing.
We put foam blocks in the GM express / Savannah Vans. You can find them on the inside, rear right quarter panel behind the plastic interior panel. We also put them in the Colorado/Canyon trucks but I'm not sure where.
Very impressive portfolio, thanks for sharing these details. Pretty sure most of your UA-cam audience has no idea about your background and is eager to know it.

Loving this series of Tesla Model Y tear-down videos! Just a small thing I noticed with this particular one, it seems the video render job was uploaded in 1080p60 instead of the usual 2160p60 (4K). I know, nitpicking, but I love to see every detail!
Dear Sandy - Greetings from the NHS secured UK. The original use of the acronym NVH was (at least in the UK) in about 1967 (a bit before your time I guess) with the release of the first Ford Cortina. NOISE - VIBRATION - HEAT. Please correct me if I am wrong.
On my Mercedes SUV I took out the front plastic wheel well liners out and covered them in a layer of aluminum foil constraint layer, a layer of butyl rubber elastomeric layer, and another layer of metal constraint... Apparently doing it exactly like this creates a sound deadening layer that is as effective as an equal thickness of lead (which is incredibly dense). I also mounted the plastic on rubber insulators when I put them back on. It worked so well that I no longer could hear the wheel noise at all...not even above highway speeds with loud mud tires, or even spinning and shooting gravel. Btw my "metal constraint layers" were just aluminum foil tape, and my rubber is a membrane for sealing basement walls. It probably added a couple pounds. Now I've been in all sorts of vehicles, the over built w140s from the 90s (with like 6 inches of dense foam in the floors and double glazed windows in the doors) before MB got bought out by Chrysler and had many of the engineers replaced...new MB, Teslas, new f150s, Austin Martin's, lexus, BMW, Audi, etc... And not a single one has the nearly zero noise level that my amateur self did. I also went back and did the rear and now all I can hear is the exhaust. I also did my doors, but not so much to keep sound out but to keep it in and turn the doors into big speaker boxes to get more mid bass. It sounds amazing. Like nothing on the market. I really don't understand why manufacturers don't do more of this considering it's so simple and light and brings down loudly audible road and highway noise to utterly inaudible. I've heard of Audi putting a carpet like material inside the wheel wells to help dampen the frequencies, I was going to try that but like I said the road noise is completely totally gone. Like not there at 100 mph not there.
We need to go change Chilton's and Haynes diapers :) great work man! Edit: your comment about cold for batteries. Please let Nissan know this. Well below freezing they let their cars charge. Heater for batt comes on at -14F. Manual page number EV-20. Btw, Quoting art of war was a nice touch...
"I get back at people".... Never try to get one over on an engineer. They are waaaay more creative at getting back at you than you can possibly imagine.
As an undergraduate engineering student I can confirm this. I don’t fuck with anyone unless they’re assholes to me or anyone else. Then I get creative lmao
Please do one of these on the wind noise on the Tesla Model 3 and Y around the frameless windows and the gap in the roof panels, it drives me crazy and would love to see a Munro explanation and even better a Munro aftermarket solution that I could buy!
My model Y still has noise and vibrations. Tesla recommends the tire pressure 42psi. I find it to harsh and stiff, I put the tire pressure to 35psi it a lot better but stiill vibrations.
15:50 - that was the most interesting commercial that I have seen, that is a pity that as a programmer who is just curious I cannot buy those reports :D
Always blown away by the stuff at Munro. I wonder if the department of health would consider commissioning Munro to look at the logistics of mass producing the portable, wearable kidney machine.
I was going to buy 10 copies of the Model Y breakdown until I found out it _wasn't_ 56,000 pages... I couldn't possibly stand to read a breakdown that was shorter than that. Holy HHHEEELLLL :)
Thank you for your explanation of what Munro Engineering does as its main business. You are at the heart of a successful capitalist economy. You can’t build a better mousetrap unless you know what others’ mousetraps are doing and how much they cost.
I once read an article (sorry, the source is long forgotten) that described how, at the same NUMMI plant in the late 1980’s, disgruntled workers would put empty bottles, etc. behind the door panels to create rattles. 😛😝😀
@@chstra45 But not just for road noise. IMHO it's place was determined by the sound tuner, who did the speaker & subwoofer tuning. Likely a bass absorbing tweak.
What Monro & Associates does have a quite good analogy in the software world. Source code gets compiled into machine code. Sure you can have the processor manual and look at what each instructions do and follow along but takes lots of time and you don't get the bigger picture. Then there are programs called decompilers that takes machine code you know was written in one language and tries to reconstruct the source code. It won't be 'nice' code always but more understandable. Sandy and the team do decompilation of products (machine code) into design and parts costs (source code). And also work with designs (source code) and optimize it - like when you use optimization flags for the compiler.
great to get a better insight into what Munro & Associates do. I'm really interested to find out if Tesla are putting more of the new parts from the model Y into newer model 3's.
excellent work Sandy.....one thing to do the work, entirely another level to Explain it for lay person, I now appreciate Elon's comment "manufacturing is hard".
Is there any way we can have Munro start a video with a carol baskin “hello all you cat and kittens” that would make my day. Love the videos keep up the good work
Fabulous. An episode about Edward Deming and Toyota Production System would be awesome. This has been adopted by Silicon Valley under various headings : agile, devops, OODA. Given the amount of high tech hardware and software in a Tesla, this synergy / duality is critical for effective/efficient operation and manufacturing. I know you respect deming. Ben Sullins is a Tesla data science guru and would probably have further deep knowledge for such an episode. Just a thought. Great to see your viewers count soar!
I would like to see a full teardown series on other cars too (porsche taycan)...im on a bingewaching campaign with these. maybe even a series on aircraft
Sandy, Your discussions regarding the soundproofing would be more helpful if you showed what was different than the M3. Many people complain the M3 is noisy and it would be helpful to point out any improvements. I would imagine the lifted floor compartment must have added a bit of sound deadening and you didn't even discuss this in this video.
Great video as always. Nice, love the molds. Light and very functional. That active shutter could have been done better, this one looks like will have some grag when closed. Lol about the foam cube. Sounds like they had either cables or something they did not know what it was or how to get to it vibrating so someone stuffed the foam cube.
Foam block is not an after thought. There is nothing else inside that space, the block keeps that space from being an echo chamber for road/tire noise.
Will you be able to determine if MY has 5G antenna or ability to communicate with Tesla satellite network? Thanks for your work and videos. It is very interesting to witness from my dining room. You left us hanging on the deading material in golf ball. Where is it being used or where do you recommend applying the material?
Jk Ia it doesn’t have either. It does have a cellular link but it’s only 4G LTE/3G. It also has @ 2.4 and 5ghz WiFi antenna. The Starlink antenna will be as big as a pizza box with a motorized articulating mount so that it can steer the beam to whichever satellite it wants/needs
pilatomic that won’t be sufficient. The articulation won’t move very far, maybe 0 to 5 degrees in each axis but I think it will require both that and an electronically steerable beam
Great video Sandy! I do not mind what you termed a ‘commercial’ as it clearly shows how your company monetizes the outputs for your customers. I am curious if you and the staff provide specific training for design teams, quality assurance experts, college course work, or whatever to keep building good practices across multiple industries. Thanks for all you do. Stay safe!
Good stuff. I used the 3M E.A.R. product in sheet form to damp hydraulic pump mounts. Amazing stuff. I used some of it sandwiched in the motor mount of a noisy outboard on a sailboat and could not believe the difference. I'm surprised to see it has aged. I was hoping to use you guys for an engineering assist on a new product development but ended up getting an offer I couldn't refuse and sold the company. Can't compete for a while but looking at some different markets. If anything comes of it I may well be in touch. Love this series. Teach the Tesla fans a thing or two about how stuff actually gets made.

True, but that fucking ball DID bounce, bro.
I think it's more like a recruiting ads than business ads. Big company probably won't go scout on UA-cam for this kind of things (just my guess).

Try ingesting a foam cube afterwards to mitigate the vibrations.

Dear Sandy - Greetings from the NHS secured UK.

Tesla is doing a great job with the design and development of new models BUT they have a long way to perfection.
That foam brick is funny. The last thing I would've expect for sound deafening materials in a car is simple foam brick lol.
I think that brick has serious meme potential. (They should have printed it with "companion cube" hearts, tho)
On my Mercedes SUV I took out the front plastic wheel well liners out and covered them in a layer of aluminum foil constraint layer, a layer of butyl rubber elastomeric layer, and another layer of metal constraint...
Apparently doing it exactly like this creates a sound deadening layer that is as effective as an equal thickness of lead (which is incredibly dense).

And not a single one has the nearly zero noise level that my amateur self did.
I also went back and did the rear and now all I can hear is the exhaust.
I also did my doors, but not so much to keep sound out but to keep it in and turn the doors into big speaker boxes to get more mid bass. It sounds amazing. Like nothing on the market.

Impressive stuff! I found that Munro's vid it's better to watch at 1,25 speed. :)
new dreamjob:
foam cube !
Please do one of these on the wind noise on the Tesla Model 3 and Y around the frameless windows and the gap in the roof panels, it drives me crazy and would love to see a Munro explanation and even better a Munro aftermarket solution that I could buy!
Sandy-The uncle I never had!
I got used to see him with the mask... once he takes it off it will feel weird
The mustache is creepy
@@ZubinB No it's cool
Watching Sandy makes my brain grow.
Tony Simi brains doesn’t grow, unless you are still embrion and your mother watching this video
@@tomasFL Yeah but neurons do so close enough
Great new opening. Keep up the excellent work.
The block of foam is an excellent choice. Even though Tesla's show some sophistication, they aren't ignoring basic tried and true solutions.
Hi Wot Nots - stay safe - love the show
My model Y still has noise and vibrations.
Tesla recommends the tire pressure 42psi. I find it to harsh and stiff, I put the tire pressure to 35psi it a lot better but stiill vibrations.
15:50 - that was the most interesting commercial that I have seen, that is a pity that as a programmer who is just curious I cannot buy those reports :D
Always blown away by the stuff at Munro. I wonder if the department of health would consider commissioning Munro to look at the logistics of mass producing the portable, wearable kidney machine.
I was going to buy 10 copies of the Model Y breakdown until I found out it _wasn't_ 56,000 pages... I couldn't possibly stand to read a breakdown that was shorter than that. Holy HHHEEELLLL :)
Thank you for your explanation of what Munro Engineering does as its main business. You are at the heart of a successful capitalist economy. You can’t build a better mousetrap unless you know what others’ mousetraps are doing and how much they cost.
learning a lot from you Sandy
Literally no one:
Engineer at Tesla: toss a foam bock in there.
It's there for a reason. Keeps sound from echoing between outer quarter panel and wheel arch.
Cheap, very cheap to install, very light weight, effective.
Smart engineer at Tesla: toss a foam block in there.
I once read an article (sorry, the source is long forgotten) that described how, at the same NUMMI plant in the late 1980’s, disgruntled workers would put empty bottles, etc. behind the door panels to create rattles. 😛😝😀
How to drive an engineer nuts? Throw a square foam block into that space, who else would ever take a look in there?
@@chstra45 But not just for road noise. IMHO it's place was determined by the sound tuner, who did the speaker & subwoofer tuning. Likely a bass absorbing tweak.
Great stuff Sandy, keep up the good work
What Monro & Associates does have a quite good analogy in the software world. Source code gets compiled into machine code. Sure you can have the processor manual and look at what each instructions do and follow along but takes lots of time and you don't get the bigger picture. Then there are programs called decompilers that takes machine code you know was written in one language and tries to reconstruct the source code. It won't be 'nice' code always but more understandable.
Sandy and the team do decompilation of products (machine code) into design and parts costs (source code).
And also work with designs (source code) and optimize it - like when you use optimization flags for the compiler.
Nice intro! Short and sweet.
Gonna bid on that foam block baby!
great to get a better insight into what Munro & Associates do. I'm really interested to find out if Tesla are putting more of the new parts from the model Y into newer model 3's.
These mats on the bottom are the same as they use under a stainless steel sink to prevent vibration ( running water and stuff falling )
'...They are like Grandma's meatballs...I get back at people....' Entertaining!
Sandy, You're the man.
Those foam bricks are most likely BASF Basotect, and they are dampening and tame low frequency sounds from subwoofers (aka basetraps).
excellent work Sandy.....one thing to do the work, entirely another level to Explain it for lay person, I now appreciate Elon's comment "manufacturing is hard".
I think you just found the Tesseract.
Mr. Musk didn't know where to hide it!... I mean Mr. Stark
Is there any way we can have Munro start a video with a carol baskin “hello all you cat and kittens” that would make my day. Love the videos keep up the good work
I came for the grandma's meatballs and other snarky remarks metaphors. I love it. 😂
Fabulous. An episode about Edward Deming and Toyota Production System would be awesome. This has been adopted by Silicon Valley under various headings : agile, devops, OODA. Given the amount of high tech hardware and software in a Tesla, this synergy / duality is critical for effective/efficient operation and manufacturing. I know you respect deming. Ben Sullins is a Tesla data science guru and would probably have further deep knowledge for such an episode. Just a thought. Great to see your viewers count soar!
That might be too valuable to show.
I would like to see a full teardown series on other cars too (porsche taycan)...im on a bingewaching campaign with these. maybe even a series on aircraft
"Hahahaha, omg! :Baby-powder! Sandy you need to do stand-up on the side my-friend!"
10:54 Nice table!
Sandy, Your discussions regarding the soundproofing would be more helpful if you showed what was different than the M3. Many people complain the M3 is noisy and it would be helpful to point out any improvements. I would imagine the lifted floor compartment must have added a bit of sound deadening and you didn't even discuss this in this video.
Great video as always. Nice, love the molds. Light and very functional. That active shutter could have been done better, this one looks like will have some grag when closed. Lol about the foam cube. Sounds like they had either cables or something they did not know what it was or how to get to it vibrating so someone stuffed the foam cube.
Foam block is not an after thought. There is nothing else inside that space, the block keeps that space from being an echo chamber for road/tire noise.
Will you be able to determine if MY has 5G antenna or ability to communicate with Tesla satellite network? Thanks for your work and videos. It is very interesting to witness from my dining room. You left us hanging on the deading material in golf ball. Where is it being used or where do you recommend applying the material?
Jk Ia it doesn’t have either. It does have a cellular link but it’s only 4G LTE/3G. It also has @ 2.4 and 5ghz WiFi antenna. The Starlink antenna will be as big as a pizza box with a motorized articulating mount so that it can steer the beam to whichever satellite it wants/needs
@@SpiraSpiraSpira I'm almost certain it will be static, with electronic beam forming, so no need for articulated mount
pilatomic that won’t be sufficient. The articulation won’t move very far, maybe 0 to 5 degrees in each axis but I think it will require both that and an electronically steerable beam
Great video Sandy! I do not mind what you termed a ‘commercial’ as it clearly shows how your company monetizes the outputs for your customers. I am curious if you and the staff provide specific training for design teams, quality assurance experts, college course work, or whatever to keep building good practices across multiple industries. Thanks for all you do. Stay safe!
Sandy, like you presentations, very informative. Wondered given your knowledge and design expertise, how would you design a reusable face mask.
Good stuff. I used the 3M E.A.R. product in sheet form to damp hydraulic pump mounts. Amazing stuff. I used some of it sandwiched in the motor mount of a noisy outboard on a sailboat and could not believe the difference. I'm surprised to see it has aged.
I was hoping to use you guys for an engineering assist on a new product development but ended up getting an offer I couldn't refuse and sold the company. Can't compete for a while but looking at some different markets. If anything comes of it I may well be in touch.
Love this series. Teach the Tesla fans a thing or two about how stuff actually gets made.
Thanks for the kind words, Bill, glad to hear you were able to land a sale of your company! We'd love to work with you if/when the opportunity arises in the future. Our contact info is up at leandesign.com Thanks for tuning in!
