I used to have a link to a home theater hifi signal test. It had test signals from a high Hz down to something like 10Hz. It would play a 15 second clip of that Hz.
I lost the link and have searched there and on avs and cannot find any mention of it.
Anyone know what I'm talking about?

Is this what you are looking for?

No, but that will do quite nicely.
Thanks!

There's also this one, optimized for low frequencies:

I'll also mention that sine waves are not useful above 500 Hz or so because moving the microphone even one inch changes the readings drastically. For mid and high frequencies you really need to use pink noise filtered into third-octave bands.

Just needed 100Hz and below, but thanks for the info. for the future.

is there any that play longer? I don't have a cd player but using my dvd as a player and it does not have a repeat.

Well crud I can only hear to 12,500Hz. My wife can hear 17,500Hz. Do I have significant hearing loss?

I guess that would depend on your age, people tend to lose high frequencies as we age. You'd probably want to see a specialist to be sure however.

I'm 102.:cool:

Well, in that case your hearing's great! Though your wife must be considerably younger, you cradle robber! :) :)
