here are some sound files which are useful in letting people with normal
hearing get some idea of what people with a hearing loss and/or Tinnitus
experience.

Interesting. Does anyone know of similar sounds for speech? I've got high
frequency loss and sometimes people start shouting as if that will help.

It is not be terribly difficult to make up sound files using a persons
speech and a sound editor and then apply filtering according to your
audiological analysis. You can then add the tinnitus as well if that is a
factor. Then let that person listen to the original and the resultant sound
files, they will get the idea real quick. I am working on this right now.

Some people talk very poorly, even sitting right next to them, I cannot
understand them, others I can easily hear across a room. My hearing loss
only aggravates THEIR problem.

Thanks for this, These really indicated to my wife what it is like for me
and my tinnitus.I couldn't hear the last sound nor the apparent background
noises to two of the tune examples.

No explanation of how the files were made found in the dangling thread.
Just static EQ will not do it, in the not improbable case it was used.

>>> Interesting. Does anyone know of similar sounds for speech?
>>> I've got high frequency loss

Undefined variable, everybody has some kind of high frequency hearing
loss, if not then their hearing extends to 32 kHz.

> and sometimes people start shouting as if that will help.

Masking theory is needed to explain why it doesn't.

It is somewhat non-simple because the recruitment needs to be modeled
too.

In terms of comprehension it equals the hearing loss. It was btw,
beatifully modelled with Homer Simpson as example in some episode of the
Simpsons. It should be easy to find it, it is one of the 3867 with a
real rockband in it.

The above considerations will have to be accounted for in the sound
design, at a glance it should be doable, but not simple.
