Diane, Thank you for your advice.When I see the audiologist I'll be sure to get tested higher than 8K. Your post really illustrates the value of our list. Where else can one learn about learn about hearing tests AND magnesium silicate before the first cup of java. Thanks again, Tom -- eagle ears-- Driscoll Subject: [pianotech] hearing test Tom, . I do think it is wise to get tested at higher frequencies than 6000Hz., because it is in those frequencies where hearing loss caused by noise exposure or aging typically start. Detecting hearing loss in those high frequencies is like an early warning signal, that you are susceptible to hearing loss (some lucky people aren't!) Testing in the low frequencies is generally not as important, because loss in those areas would probably have been detected long before you turned 55, as they are generally caused by diseases with a genetic cause (and other symptoms) or specific low frequency exposure (submarine's). When you make your appointment with the audiologist, be sure to request testing at higher than 8,000Hz. Also, pure tone testing is only one part of a complete hearing test battery. Diane Hofstetter
