Sine waves...

I've been listening to some 25 Hz sine waves lately and hearing them. :-) And a lot of other tones in the range up to 200 Hz as well. And crawling around on the floor groping and twiddling knobs...

I've been also been listening to some 30 kHz sine waves, but not hearing them, as expected. Not really hearing anything above 14 kHz these days, 50 years ago it was up to 21 kHz. :-(

Also, using gain settings common for large scale orchestral music I've been listening to some 440 Hz sine waves at low level (-97 dBfs) and hearing them. These were audible in both 16 and 24 bit formats, but dither was required with the 16 bit format to hear the tones. I have too much noise in the room to hear quieter tones unless I turn the gain up to unreasonably loud levels (louder than row A concert levels).
