40hz and 12khz sine wave audio test plus Philips PM3256 scope display

cheers to dak_com for the audio - lost the dak audio but the final 2 sinewaves are 10000 hz - wich i can see but not hear, and 12000 hz, ditto. I can hear the 40 hz in my sony headphones no problem but i reckon im deaf 10khz and above now. unless no one can hear the 10k sine wave ? it shows up on the scope so it must be there lol

I have an iMac outputted to an old early 70s SONY amp with old fat & heavy custom speakers I can hear everything quite well. Thanks!

The 8000Hz is killin' me! OUCH! I think I'm deaf!

I heard the 10k sine wave. I am using headphones though, they are decent.
