Say What?


Along with the aphasia, I have a hearing problem. Telephone Voice Band, what frequencies are needed for hearing, is roughly 300 Hz to 4,000 Hz. This is what my ear right does, not as good as we had requirement for our telephone circuits, but -25db at 250Hz to -10db at 2KHz to -25db at 4KHz. Left ear not too good, -30db at 250Hz, rolling off to -65db at 2KHz, even down more a -95db at 4KHz. If I was pulling a three-tone test my circuits would have to be taken down for repair or replace.
