[Elecraft] Tinnitus and the K3 RX EQ and Related Variables

[Walter Underwood]

I’m not quite clear about the audiologist’s recommendations. Did they tell you to avoid loud, high frequency sound?

If so, ask them whether they consider 3 kHz to be high frequency. That is the highest frequency you should hear from an amateur SSB signal. Unless they and you are in ESSB mode, which would make it 4 kHz.

I expect that they don’t consider 3 kHz to be high frequency. If that is true, you can do what ever you want with RX EQ.

I will not mention or ask about any of the contributing neurology, physiology, psychology or any other medical ology lest this post be branded with the Scarlet Letters OT.   Other than to say, that to avoid making the situation worse I am told I should avoid exposing myself to audio environments that would make the underlying acuity loss worse.
