My ears are not great. They hear well (normal enough per tests) without hearing aids, but background noises like in a busy restaurant causes hearing issues with others sitting at the table. Cannot block the background noise like when younger. I do hear 20Hz to 10khz. Now, listening to a HF SSB radio in a quiet room can be difficult to understand all the words if not a strong signal. And, I am not stating only weak signals either. DNR makes a big difference on new and older radios, but older solid-state (non op-amp) HF radios are much easier to hear speech details clearly vs new radios. Same with tube HF radios- ultra clear sounding. The audio clarity is much better with older radios and it has nothing to do with narrower filters in new radios either. I use an Am-Com DNR speaker on these older radios. BTW- I never can use the tiny built-in speaker in newer radios. I seriously cannot understand a lot of the speech with the tiny internal radio speaker. I always use a larger and high quality external speaker. Anyways, are new radios just having lousy audio quality that young ears do not pay much attention to the quality? Anyone else notice what I am stating?
