I'm looking at some sound suppression.

I have a friend that has sensory input issues (autistic) and I’m researching some good sound suppression for her. I came across something by a company called Pro Ears and they have an inner ear solution that they are calling Audiomorphic.

Now to someone that’s not an audiophile all that means to me is that it’s some hybrid audio device. Do any of you know what it is and how it works? I mean without directing me back at the manufacturers propaganda page :)


<edit>  The reason that we're looking at passive noise cancelling is that she can't deal with the pink noise that results from ANC.  </edit>


Those audiomorphic units basically allow sound that fall below a certain threshold (decibels) to be heard while blocking louder sounds that exceed the threshold. That is one type.

There is another type only allow a certain preset frequency range to be heard, while blocking all others.

One can be more effective than the other, depending on your particular application.

There are also some that can do both. Block high sound pressure levels as well as preset frequencies. As you may expect. The more you get the more they cost.

I have tried them all. Luckily my employer at the time (US govt.) paid for them.

I suggest contacting an audiologist or an otolaryngologist for a consultation. They can give you the best options for you friend’s needs and have a pair custom molded to fit your friends ear.

They are nice, discrete and you can’t even see them these units unless you are looking for them.

Best wishes...



I use various passive ear plugs (Flint/Mack/Pro Ears).

The PE's are more expensive @ $10-$15/pair, but she really needs to try them for comfort as well as sound blocking function.

Some sizes of the foam plugs slip out of my ears, some larger ones are uncomfortable after a while and our cats like to squirrel away the corded PE's when I lay them on the bedside table.

I wear them for migraine and to reduce TV SPL's when my wife watches @ night (only TV is @ the foot of our bed).

I find all the cheap ones to be about the same sound wise (maybe minus 25-30 db) with a TV putting out 80bB+, but I rarely wear them in public as I tend to stay home with headaches.

Seems that the foam ones I used in the late 60's/70's/80's performed better than what is currently available, but perhaps I'm just getting more crotchaty.



 Thank you ellajeanelle and dekay for taking the time to help with this.  I will suggest the audioligist and that other thing I'm not going to attempt to spell.

Good luck.

Some medical doctors have a tendency to NOT recommend specific products (these are probably the good ones;-).

My wife is going through a similar scenario with her hearing assessment via our healthcare and actually obtaining specific hearing aids.
