hi MathsIsFun

You can try it yourself:

followed by a scale and a button labelled A.

I know I'm getting deaf in my old age but I couldn't hear anything from this. Should I be able to hear a hum?

Hi MathsIsFun;

The page is Interesting and Informative. All aspects from compression/rarefaction to Doppler Effect have been covered.

Brilliant work!

Hi;

Had to turn the volume up and down but was able to go pretty well through that sound test.

Excellent page.

Thanks everyone! Excellent hearing, bobbym.

You may be in Internet Explorer, bob, it does not have a thing called "AudioContext" so my code doesn't make any sound.

hi MathsIsFun

Thanks for the explanation. I have tried chrome and it works as expected. Sadly my ears don't . My wife has been telling me to go and get a hearing check. I think you've just prompted me into doing exactly that. An additional use for the page that you may not have planned . Thanks.

I might put the typical hearing sensitivity graph just below the sound generator so people don't freak out though!
