Hearing Aid - FM Simulation
Вставка
- Опубліковано 4 жов 2024
- A simulation of what speech sounds like when recorded first through a hearing aid, and then through a personal FM system linked to the hearng aid. The demonstration takes place in an empty classroom while the presenter walks toward and away from the "listener" and while competing voices are played in background. To view the Captioned Version, search youtube.
This is the best FM simulation I have seen - thank you for producing this. My son has a moderately severe hearing loss and uses hearing aids and an Inspiro FM system in school - it makes a huge difference for him! I have forwarded this to his speech therapist and will show it to his pre-kindergarten teacher as well!
My granny has had hearing aids for year and it only popped into my head the other day that they wouldn’t of ever sounded the same for her to hear, so I asked and she told me that she can’t even remember what it was like to hear normally. Thank you for making this video it’s the only one that really shows what it might be like for her!
i have hearing aids... I don't know why im watching this lol
Jessie Star lol
Jessie Star lol
I CANT BREATHE MY DEAF FRIEND WATCHED THIS WITH HEARING AIDS TOO
I don't have hearing aids yet but I am hearing HIV positive
Im watching to see the accuracy and if its worth sending to friends and family
Thank you for this! I give this link to every teacher my daughter (who is hard of hearing) has in school so they can understand how sound is experienced for her with her hearing aids, and with the FM. THANK YOU!
thankfully, the tech is improving constantly!
with every new pair of hearing aids I get, the sound quality is slightly better!
I am an audiologist and have a student where a FM was indicated in their treatment plan but the school did not follow through on getting the FM up and functioning. This student was without adequate hearing help for numerous years until the family finally discovered that the school had the proper equipment, but just wasn't using it appropriately due to misunderstanding, etc. Make sure your kids are benefitting from this technology and your school is using it appropriately in all classrooms. Have a good talk with your child and make sure that they are getting all the information! Advocate! It is your children's future...
This is fantastic!!!! My son wears a BAHA device and *this* is what we try to explain to his teachers all the time! Some get it and some don't. Everything is amplified!! I sooooo wish that I could have had this last year when my son was in second grade!! His teacher then just didn't even try to understand! At the school where he is now, the teacher wears a microphone and has a surround sound system in her class. It makes a huge difference. Thanks for this. I am definitely sharing!!!
Now that FM systems have gone digital, repeating this test would be worthwhile - especially if you could bring in a typical RF interference source. The thing I like about Phonak's Roger is, much like contemporary digital "walkie-talkies", it'll frequency hop on its own.
What an awesome video! I will definitely be sharing this. As someone who not only has a moderate-severe hearing loss, but also has a child with a hearing loss as well, this is a perfect tool in helping others understand just how beneficial ...her FM system is in school (too bad I don't have access to one for my college classes).
We are forever grateful to John Sexton for his advocacy in getting the school to purchase an FM system for Emily. She has done remarkably well!
Thank you for this video! I work with hearing impaired and deaf students as a special education teacher. This video gives such a great insight into what my students are experiencing and is so helpful in explaining to other teachers and staff about the importance of using the FM system.
Incredible and completely accurate for my healing loss. Thank you for educating others!
Thank you for this clip. Can you do another with updated technology please. This is a great resource to show my teachers and parents.
I’m deaf in one ear but like why is this so accurate tho…
I wouldn't get too hung up on, "It does/doesn't sound this way/that way." The spirit of the simulation is to show the impact of environmental noise - which most every hearing aid wearer will tell you has a disastrous effect on intelligibility.
I think these simulations pose a challenge. The original signal (speaker) was mic'd, processed, and played back in the hearing-aid. Then the researchers mic'd, processed, and played back the audio again on your computer.
If you're wearing hearing aids to watch his the 3 stages happen again. Each time there should be some change, even compromise or degradation, of the signal.
I happen to have typical hearing YET I also stick heading aids in my ears frequently (sound-checking my daughter's). The overall fidelity is similar (although her new 2016 Phonaks are really clear with a lower noise floor than her 2013 Nios), even taking into account her programming and gain (she's -70dB on average).
As 10dB is a perceived halving or doubling does that mean everything must be 128 x louder or is it just in the highs. I'm surprised you can hear anything with 70dB of hearing loss. Conversation would be reduced to the level of a wristwatch tick. You would need someone shouting into your ears with cupped hands for it to sound normal....
Also, the mix ratio (FM-hearing aid mic balance) is crucial: With a greater balance towards FM, the results are even more dramatic.
Also, check out the ReSound Unite Mini Mic ("spouse mic"), which is a direct replacement for FM.

You are right about there being a drawback of FM systems; they are subject to stattic interference at times. It can occur when the transmitter is too close to large metal objects, for example, or if the microphone/antennae cord is bunched or wound up. Sometimes it takes trouble shooting to find the source and elliminate it, or select a different FM channel which is usually an option.
I hear the voice, but I'm still unable to recognise words.
@edukacjainspiracja
We really appreciate your enthusiastic reation! We were very pleased with the way it came out. I use it all the time in every school I go to, and it never fails to make an impression. My students have shown it to their classmates too. Please get the word out - I'd really like the video to be seen as long as it is relevant to taday's technology. -jim

"I can't hear"
Hi I'm an HOH person. Back in HS I was fitted with my first HA. It was suggested that I get an FM system but being 16 I was not open to getting an FM system. Now I see it would of helped me so much more in HS and college. I wish I had gotten it. It's probably to late. I felt my HA was good enough as it amplified everything.
Another good point! I believe we used the default setting of the manufacturer at the time. Listening subjectively to speech through the FM mic at 12 inches, we judged it about even in volume with speech at 2-3 feet from the hearing aid with FM off. We were going for transparency but did not have a way to verify that at the time.
Ha! Excellent observation. This was an empty classroom with cinderblock walls, tile floor, and aboustic tile ceiling. There was not much on the walls (college classroom during intercession). My subjective guess would be that the T(60) was close to 1 second, where I believe ANSI recommends no greater than .7 seconds. We did not measure this. We felt that this room was appropriate to demonstrate the positve effects of the FM microphone in a challenging situation typical in many classrooms.
amen to people doing this type of research 🙏
@lucyalyce
Hello - Your friend's point is well taken. When we originally produced this, we were focused on presenting the audio track to hearing people who really needed to experience how the speech signal becomes degraded when listeing with a hearing aid at distance and in noise. We did not anticipate a widespread audience, nor did we have the capability to add captioning. We are now looking into making a captioned version. Stay tuned:) And thanks for pointing this out.
I'd rather sign.
I shared this on my facebook page, and it was pointed out to me by someone with hearing loss, that if you can't hear, this demonstration is useless. It also does not have captions. How disappointing. This should be geared to all audiences.
We used one hearing aid with one audio input, so technically this simulates only monaural hearing with deafness on the other side. Technically, this does not simulate hearing loss. We are hearing the speech recorded through a hearing aid (set with gently sloping high frequency emphaisis) with whatever hearing the listener has - normal or otherwise. Additional processing/filtering of the speech signal would be required to simulate various patterns of hearing loss.
This is incredible! Thank you so much for making this!
Hi Krystal -
It's never too late! These systems can be helpful in many situations around the home and at the work place, and sometimes the best way to find what works best for you is a 30 day trial period to try one out with your day to day activities. I encourage you to visit your audiologist and see what options are out there for you. Most states provide Vocational Rehabilitation services which may help you with the cost, which can vary from @ $400 to $2000 for personal FM systems.
I wish this was captioned!
Great simulation demo! What happens in a situation where there are two students who are HOH relying on FM simulation? Is there interference? If so, would an infrared system be best instead?
It is interesting that no one has discussed or commented on the poor acoustics of the demonstration classroom. The environment and acoustic treatment would support and reduce the reverberation time, and improve SNR for the HoH person. I would be interested for this exact simulation to be filmed in an acoustically designed classroom, with an RT of 0.4 seconds - the requirement for a classroom setting.
Very well explained. Congrats!
I would encourage you to shop around. There are advantages to going through an certified audiologist who is not affiliated with any one company. That way they can give you several options within your price range. Personal FM systems vary in price from about $400 to $2000 depending on the quality and sophistication. Make sure the manufacturer has a one or two year warrantee and is a reputable company.
That's a crap hearing aid, my hearing aid quality was much better
mine too.... i think this video is only making our daily lives harder as hearing underestimate us more thanks to videos like this.
I think it's just a really old video. Hearing technology has come a long way since this was released.
This video is what made me put off getting hearing aids for years. I didn't think I could benefit, because my natural hearing is so much better than what's shown here. This video is a terrible disservice.
HI Libby - We have an open captioned version available for download on our vcdhh.org website: family and consulting services. I am planning to upload it to You Tube in the near future. We wanted to have 2 separate versions because we felt that the effect of the poor signal conditions is somewhat reduced for the hearing audience when the script can be read as the messages are spoken. Thanks for the offer though:)
Someone at my middle school had something like this. The teacher and guest speakers wore a kind of lapel mic for them.
Thanks for the feedback. I just discovered that the Regional Consulting Program portion of our website is malfunctioning. The captioned version of our film is indeed missing. We will rectify the situation as soon as possible. Sorry for your frustration. Please check the site again soon. Thank you.
Actually the bandwitdth of the new FM transmitters out there is relatively good - out to @7,000HZ - not sure about the bass, which is probably limited by the acoustics of the receiver/speaker of the hearing aid. Also a bass boost would interfere with speech clarity, and that's the goal of the system. So, the system sounds only as good as the hearing aid it is transmitting through plus the distortion of the hearing loss itself.
This is a great video, and I have been using it in my teacher education classes for several years. This semester, I have a student who is partially deaf and am very surprised that this video has no closed captions. Kind of ironic that a video about accessibility is not accessible. If I'm missing something, please let me know.
they reloaded a caption version on the channel, check that
Thanks! This is really helpful :)
There is a captioned version now on You Tube if you search for FM and Hearing Aid Simulation Captioned. I am unable to post a link here. Thanks.
Its actually much harder to hear him as he gets closer for me. The noise to sound ratio is thrown by a high pitched feedback. Nails on a chalk board. Give him a microphone pa system and send the audio over WiFi to the students laptops. They can plug in ear monitors into them. I'd make it from my old pro audio equipment and some adaptors and shit from radio shack. Old m audio card, a spare mic with an xlr out, an n router. You get the idea. Programs for this exist. Schools are always getting rid of old PCs and stuff. Make it work. hearing aids are in ear monitors, just get ones with trs out. 20 years ago I'd have said run quarter inch trs fatpipe to headphone amp with 4 outputs and tape down the line. Studio style
Why aren't there closed captions for this video???
This video is literally designed with hearing in mind and for people who can hear There is no point in there being captions on the video lol
thanks for sharing!
Thank you.
I have a friend who is completely deaf and she has hearing aids and I was curious to know what it sounds like
Good Lord, I can't hear anything he's saying! I am NOT kidding!
Have hearing aids improved since this came out?
In my opinion, yes. When I had my older hearing aids I never heard birds. Now that I got new ones it sounds less like I’m trapped in a cookie can and I can actually hear birds and the wind.
I can’t watch this. No captions.
Very disappointed.
It's a speaker inside your ear canal
this... this isn't normal hearing????
I just got top of the line hearing aids this past week and the ones you are demoing are garbage compared to the ones I have.
Except for the sound equalization, people with SSD (single sided deafness) have exactly the same issues with their normal ear with background noises and presenter distance as shown in this video.
frschmidlin do you mean unilateral hearing loss?
@@emmamayes9861 More or less. Unilateral Hearing Loss (UHL) might means a partial hearing loss on one side. Single-sided Deafness (SSD) is a specific type of UHL that means complete deafness on one side.
I"m from Canada and I got services else where But since i won't in school for awhile. I think I'll hold off and when I go back I'll tell my audiologists what i've discovered.
Amazingly done. But how you are able to show the sound with hearing aid and through fm transmitter( in this vedio) how it is been played. Pls pass that information
@Jim: I'm listening to this through direct audio input (DAI) to my hearing aids, and I can tell from even the first 40 seconds that the classroom does NOT meet ANSI/ASA S12.60 for reverberation time T(60)
What really sucks is that the FM systems suffer from excessive interference from other devices and signals!
Explains to hearing people how we deaf hear with tiny residual hearing. I don’t understand a word, I’m 🧏♂️ DEAF, I wear 2 Hearing aids all day long.
Could you add captions to this video? I have created captions using CaptionTube, if you would be willing to upload the captions I have I could e-mail them to you.
Hi Jbombicino, thank you for this video. Can I use some parts of this video in a new video please? I'm making a video to inform teachers in Flanders.
Great !!!
I can't understand this due to my hearing loss and the cc are a jumbled mess. Went to your Vermont site and the captioned version was missing. This is so frustrating !
If this is what it sounds like I don't think I will get one because it sounds bad.
It would help if the video was captioned. I can't understand anything.
There is a separate captioned version on You Tube -
Hi - There is a captioned version on You tube - just search for it:)
What the heck?
Hearing aids suck!
I have mild hearing loss and I thought about getting hearing aids.
Now I changed my mind
This is more accurate for people with more severe hearing loss, you should be good. They should also let you try them before you commit
Is there any whistling? jbomicino
bless
What is the link to the downloadable, captioned version on your website, please?
Who's watching this with hearing aids on?
I can't hear you ;-;
sounds tinny
cant hear one word
i cant understand a word your saying and im wearing aids and there is no caption
There is a captioned version also posted on You Tube - just search for Hearing Aid - FM Simulation Captioned :)
Hello
hello

2:20 - 2:35
I jave
For the amount of money a hearing aid costs you should be able to get a better sound than this. It sounds worse than the speaker on a mobile phone!
This video should be removed. This is not what hearing aids are like at all. Your scaring people and making it seem that hearing aids won’t help which is BS.
@Ollibeantv
And thank you for viewing and sharing this with people you know. Please pass the word - We want teachers, parents, and administrators to experience the difference with wireless FM technology!
Greetings viewers. Just a reminder....there is a closed caption version of this video on my channel...just search Hearing Aid - FM closed caption. Cheers.
