Re: Optimum tone freq for detecting a weak

Bo, OZ2M


My empirical findings are that most people prefer somewhere between 600 Hz to 700 Hz. Some below 600 Hz and very few above 700 Hz. I haven't got a clue why 800 Hz ever came into the picture since not many listen to CW at 800 Hz.

Attached is a single slide from one of my presentations at the 2018 RSGB Convention showing the sensitivity of the ear vs frequency and age.
