That's the breaks. Hearing aid companies have all kinds of schemes to reduce noise and increase comprehension of their products. The dirty little secret is that the people selling hearing aids don't know what their products are really doing because all that info is proprietary and closely guarded.

Im afraid so...that the salesmen dont necessarily have the real info on the products. People are so worried about suits, proprietary information, etc, AND justifiably so. Nowadays, with the instrumentation we have, it is impossible to hide a secret about chemical formulations. What is harder is to learn the process one might use to make those chemicals. Would you believe that the process to make ethylene oxide, the precursor to ethylene glycol antifreezes, only yields 1-2% product on each pass through the plant? It is true. BUT, in an enormous plant, 1-2% can yield millions of pounds of product per year. I have been in this business for 45 years, and am still learning. When I graduated from the university, I thought I knew every chemical reaction known to man. My first boss, a lady, told me that " now it is time for you to learn some chemistry". She was right, and I have been at it ever since. Thanks for your post.

A trade journal would be a better place to > start, or would it? :-) Or, 1) buying a car from a reputable and successful automaker that is not currently owned by a union or a government, and 2) following that automaker's maintenance and repair instructions, on the premise that they're probably pretty good at what they do, otherwise you wouldn't have spent good money on their product. Personally, I find that 1 & 2 work fairly well when one is not in a position to be able to discern whether or not any given chemist (or chemist-wannabe) is talking rot or not. -- Tegger

When it comes to hearing aids, this is bullshit. Sorry. -- Tegger
