Cyber ears

[Kevin S. Riggs]

Hi Folks,
 Been reading for a year, this is only the second post.
In reference to Ron's post there is a patent (#4253374) filed Dec. 7,
1978
by Peter C. Watterman for the audible beat enhancer you describe.
I also independently developed the device, with the addition of a
real-time
beat frequency counter. Its' purpose was to aid in learning beat counts
and to help hear the beat in noisy situations. It actually works
reasonably
well and is not expensive to build. Robert Scott is correct that a good
human
ear can detect the beats longer in a lot of situations. However, there
are other
situations where the reverse is true. There is at least one person with
hearing
problems that claims he can hear the beats when enhanced but not
otherwise.
If anyone is interested, there are a couple of .wav files of
beat enhanced major thirds at
