Re: Sound Waves

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?

Re: Sound Waves

Hi MathsIsFun;

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

Brilliant work!

Re: Sound Waves

Hi;

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

Excellent page.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Sound Waves

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.

Re: Sound Waves

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.

Re: Sound Waves

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