Best one of these I"ve found on UA-cam! Testing new monitors and felt like my Right Channel did't have as much top end as the Left, but it"s either my room or my ears (it would make sense I'd have some hi freq hearing loss on my right ear due to bad monitoring setups as a touring musician) . But the speakers are working great. Thank you!
Read the description if your wondering why you cant hear anything thats what I had to do. This is especially important if your watching the video on a cell.
Making this to I can quickly go through the tones for balancing the EQ for my headphones 31.5 Hz - 5:00 63 Hz - 8:00 125 Hz - 11:00 250 Hz- 14:00 500 Hz - 17:00 1 kHz - 20:00 2 kHz - 23:00 4 kHz - 26:00 8 kHz - 29:00 16 kHz - 32:00
Ooft, slowly cranking the 10hz feels like a demon is creeping up on you, love it. Also, why does the test tone stop at 16khz? Kinda defeats the purpose, no?
Try it with duodayton18s @500watt, sealed 3.74 cuft each ,4 bolts 3/8 in through cabinet around the drivers then use tones @ frequency and torque the resonances before the glue sets lay on back and pre fit the drivers,do the stress procedure and make the best bang for buck bass unit put it on rollers!
i was able to hear the 16hz! depressingly however, 12.5kHz was the last frequency i could hear...and i’m only 29 years old 😢 oh well, probably from the OBSCENE amounts of live shows i attended when i was younger and thought absolutely nothing about standing directly in front of the PA loudspeakers that were made to throw the full sound of the performance all the way to the back of a crowd of thousands...dont regret it a bit 🤘
Every time you leave a concert with ringing ears you will have lost some hearing that will never come back. I blame Springsteen. Melissa Etheridge, and a few others for my loss. Nothing I can hear above 12Khz. Lucky for me I was young enough and the Beatles were not as loud as many current bands. Glad they were my first concert ever. Seattle 1966 or 67. Amazing but the full show spoiled me because I expected that many acts to be on every concert thereafter. On the bill were Bobby Heb The Ronettes The Cyrkle The Remains Pretty good for a first concert.
@charlesclarke7790 I couldn't hear the lower frequencies but I was on my cell. I'm going to try it in the studio meet. Although I'm not totally sure how or what I should be using this for. I just know deep down it's important to my studio acoustics.
@@geezer805 A strange statement) If it were true, then all musicians and sound engineers would by definition be deaf as a cork) However, this is not so. Perhaps you have good acoustics, since many who claim that they hear 20,000 Hz actually hear combination harmonics of lousy acoustics that fall well below 20,000, and conscientiously flatter themselves)
Many practical uses like giving enough time to find the problem causing audible buzz around a particular frequency, without having to rewind constantly. For a quick stereo test, you don't want this - use the Fast Audio Test video.
Thanks, I had my speaker inputs swapped the speaker cables are not the same color as the computer input and all the sound was coming out of the center speaker and subwoofer.
You know I made 4 downloads of 4 test, and all of them seems to not do the higher vibrations which I guess makes sense as they are found on youtube who most likely recodes the sound stuff again and don't run with those higher hz.
thank you , should have mentioned the music scale, pure tones, etc. wrote it, to see (hear) where each note actually steps up , where the missing # s are.
Interesting request. Curious what are you using the test for? These specific frequencies don't perfectly match any musical pitch frequencies (standard 12-tone scale), but I may make a separate test for that if there's interest.
@Jonah Whale Definitely not normal - I would double check your amp output spec (esp minimum impedance) and also measure DC resistance on the speaker terminals (after disconnecting from amp) to make sure they are within spec and haven't shorted. The amplitudes are 14 dB below full scale (-17dBFS rms), so under many other tests/music and within ballpark of the Fraunhofer LFE test.
@Jonah Whale Good to hear, although I'd still suggest at least doing a quick resistance test with a cheap multimeter on your speaker terminals. If a speaker voice coil wire shorts (e.g. by melted insulation), that means the amp will see very low impedance and could overheat. It's a good sign the thermal/current protection seemed to work, but you don't want to be pushing that edge too much.
@Jonah Whale Hope the repair works out. Sounds like it would be best to have an audio/speaker technician take a look and troubleshoot. The sine test tones can actually be used for this kind of troubleshooting, but you're right it's important to be careful with any of these kinds of tests. I'll put more emphasis on this in the video materials.
@@OutlierAudio I just wanted to be able to play 1/3 octave steps, and be able to hear if certain frequencies were louder, or quieter, to help me tune by ear, with a DSP. But honestly, I'm starting to think I've done most of what's possible already. I really just need a laptop and mic, to listen to my system and shoe me the peaks and valleys.
@@Chris_Wolfgram Got it - I wouldn't recommend sine waves for tuning any speaker by ear. They really can't represent the spectrum well, even at 1/3rd octave. If you do any tuning by ear, I'd recommend real music tracks that you're familiar with (how they should sound on a well calibrated system). Otherwise you want to be tuning with measurement data from an actual calibrated mic & preamp at multiple positions.
Hello, is it possible, or is there already an audio file that has all the audible frequencies in sine, saw and square. I’m looking for an audio sample that would contain all frequency permutations. Any help would be greatly appreciated 👍
It’s quite a strange experiment, is it possibly to hear a song by the absence of sound, not just by its addition. So you subtract the frequency range from the full FR using any particular song. Can the human brain hear the silence? It’s probably crazy but I’d like to know. Any ideas?
I don’t think that’s as responsive as I need. Say we have a song that’s 3 minutes long, we also have a full frequency spectrum for three minutes. We subtract the song from the FFS and are the left with 3 minutes of the FFS minus the frequency positions produced by the song. I’m interested to know wether the human brain could figure out any kind of sense. What do you think?
Mmmm... I think I know what you're trying but you probably need to learn a bit more about how waves work. You can't have "all" audible frequencies, because any frequency is infinitely divisible (10, 10.0001, 10.0002, etc). At best, you could (for example) do all frequencies mixed at .1 hz intervals. But even then, you wouldn't really be listening to "all" frequencies at the same time; as you pointed out sine, square and saw all sound different. This is because (among other reasons) what you are hearing isn't just the main frequency, but all of the harmonics. IE, if I sample a pure 100 hz tone and look at it in frequency domain, you will see spikes outside of 100 hz based on how perfect the tone was (IE, close to sin) and how long the sample was. Similarly, a steep notch filter could blot out all noise around 261.63hz, essentially "silencing" C, but if you put the same filter on a piano playing the same note you'd hear some sound from outside the notch filter. So at BEST you could probably create a nice broad-spectrum noise and then move a notch filter around to the tune of "happy birthday" or something, and maybe that would be audible/interpretable. That's a good experiment. But a "song" with complex instrumentation cannot really be carved out of the noise the way you imagine. Alternatively, imagine taking a fourier series on a 3min song. Now create a new series, and just make it a solid mass: that's pure "noise", but when you reverse the translation you'd just get a DC signal. If you tried to perform a mathematical operation (say, subtracting one from the other), you'd get the song, with altered frequency response and possibly inverted phase, depending on the "noise" you created. I don't mean it would be recognizable, I mean it would be IDENTICAL. Hopefully that helps.
Man if u wanted to prank someone just wait till there asleep turn on a bluetooth speaker or put headphones on there head slowly so u dont wake the person up, play the frequency when it hits 12.5 khz exactly and turn the volume up all the way lol
Thanks. I was wondering if you had the time to make a sine wave for the whole range of a guitar. I have several high end solid wood guitars that I hadn't played in a long time. It helps to reopen them up without playing when they had been sitting for months. Thank you if you have the time.
In this context you can "hear" the infrasound for two reasons I expect. Firstly because it was uploaded to UA-cam and secondly because of your playback device. I suspect that UA-cam isn't designed to handle infrasound so it may interpret that data oddly, hence why a deep wub wub wub sound can be herd. In other words it doesn't know how to interpret that input harmonically so it breaks it up and plays a deep tone 10 times a second instead of a tone that oscillates 10 times a second. Even if the data that says "this is 10Hz" is maintained your headphones aren't equipped to deal with that. So it's not so much that the video has falsely presented itself, it's the equipment that's failed us in this case... well that's my guess anyways.
10 Hz can be a useful audio test tone for various reasons. Can be felt by the body but not heard by the ears (and if there's audible sound/noise, that could indicate a problem). 10 Hz will move most any woofer cone in open air or ported enclosure, useful for testing excursion-correlated problems, measuring excursion limits, etc.
I have a friend with a home theatre that has subwoofers that can reproduce frequencies at useable volume all the way down to around ~7hz, and I know there are others with even better systems. Sound at and around 10hz is very important to anyone looking to make a quality sound system for movie watching. Many movies go down to 10hz and below it, and 99% of people never even know that those sounds are in the movies, but when you hear (or feel it ;) it on a good system, it's a night and day difference. Finding Nemo goes down to 5hz during the scene with darla tapping on the fishtank glass, if that says anything XD
Count yourself lucky ... mine stop at 9khz for the left ear and 10khz for the right. Listen to all the high quality recordings you have now, while you can appreciate them!

I lose audio at 32 minutes exactly, I also suffer perceived tenitius so maybe my stress isn't real but I do hear a tssssssssssss daily
First of all, my lower threshold is 16 Hz. Second, UA-cam doesn't fully allow sounds above 16 kilohertz just yet.
Yes... just hooked up a scope to it. From 12.5 to 16 kHz it just went to zero
What did you use to measure your ability to hear 16hz? Do you have a subwoofer?
@@bailey2517 I used headphones and estimation of what C 0 should sound like.
@@bailey2517 i can hear very clearly the 16 Hz section with my Sony headphones.
@@MidnightSky69 ok
My right channel was intermittent. This proved that I have a bad input on one of the HDMI connections. Thanks for the upload
Good for tuning SSB radio frequencies, many thanks dude !
Thank you for making this. It is very useful and better than other similar sorts of videos
It's the 90 / 10 Hz rule: You have replaced 90% of what I use a signal generator for with a single (signal?) vid. Very clever!
It was one of best kind I ever came across, A great job man
I have used this video many times to check my bass response and subwoofer to main speaker integration. Thank you for doing this!
this is so useful in so many ways. i ve sorted a lot of problems in my room with this video.

Very powerful frequency and amplifier test very best audio frequncy
also be super cautious even at 'inaudible' high freqs because if you turn it up too loud you can burn a voice-coil easily if you have enough power.
