Thank you for sharing this information. Your understanding of audio frequencies, etc. is far greater than that of most people. The basic audiogram is confusing to many without a thorough explanation. There will be a great deal of discussion coming to the public on the new OTC hearing aid law. It will be interesting to see how people do with the new devices.

Hearing loss tends to be progressive, so it's quite logical that many who start with OTC devices may have to eventually upgrade to more sophisticated technology. Time will tell. The mere fact that untreated hearing loss, even that of a moderate level, can lead to cognitive decline according to studies from major research bodies, tells us that we need to find solutions that work. There is no one size fits all.

Another very real issue is the reality that hearing loss, especially that of adult onset, can drastically change a person's life and lifestyle. The psychosocial impact of this invisible disability is well documented. While OTC products will same money for many who can benefit from them, the support and counsel provided by a well-trained hearing healthcare specialist is hard to put a price tag on.

I encourage you to join HLAA and become involved in the educational programs that are a part of the organization's mission. Are you familiar with HLAA? http://www.hearingloss.org
