Zebras is right.
I wasn't "daisy chaining" your program with my hearing aids in the way an engineer would think.
I was simply using my hearing aids to get enough volume so that I could tell a difference between your programs.
It might be helpful/it would be awesome if every hearing person were forced to be deaf for a day...
If you want to get a sense of what hearing loss sounds like, go buy some good ear plugs and find or borrow some industrial ear protectors.
That combination will give you a glimpse of what 40db (mild to moderate) conductive hearing loss sounds like.
Keep in mind that people like me have hearing that starts at 90dB (and keep in mind that decibels are logarithmic).
For sensriouneural hearing loss, you have to add in a loss of frequency resolution (for example, I can't tell the difference between two or even four piano notes) and distortion (high pitches sound like static to me).
Severe to profound hearing loss doesn't mean the absence of sound, just the a sense of sound that would be helpful. I can sometimes tell that there is a sound but it makes no sense.
I can't tell where the sound is coming from, what it is, or what it means.
