I am grateful to the professionals and experienced hearing aid users who generously answer questions asked on this forum.
However, is there any published book or website that explains hearing aid specifications in more detail, sort of like a “Hearing Aids for Dummies” book that would discuss things like the meaning of the different graphs hearing aid manufacturers use in their specifications, e.g. 2cc coupler, OSPL 90, Ear Simulator, meaning of reference text gain, distortion, equivalent input noise, frequency range specifications, bands vs. channels etc.)
Perhaps one of the professionals on this forum could recommend a textbook used for a college class on “Hearing Aids 101.”
On a related issue, it would be good if hearing aid manufacturers would explain in more detail their different features and what they actually do. It seems that there is a lot of jargon used that is not standardized among different hearing aid manufacturers or explained on their websites or in their literature. For example, one hearing aid company might list in the features of a particular model that it has an “Environment Optimizer” or a “Speech Guard” or a “Wind Noise Monitor” or “Auto-comfort in noise.” What do these things actually do to the frequencies the hearing aid is providing? And do I actually want or need those features enabled on my hearing aids? Another company would use different jargon, perhaps for the same features.
I like to be an educated consumer, and study details of a product before I buy it, whether it is a car, computer, or hearing aid.
