Re: Filter PET scanner noise (fwd)

[Tom Brennan <g_brennantg@xxxxxxxxxxxxxxx>]

I had intended to send the message below to the list and see that I didn't get
it there.  I'd be interested in feedback from the group as I am also doing some
high noise work.

Subject: Re: Filter PET scanner noise

You might try a throat mic although speech quality will be somewhat compromised.
I have used bone conduction mics but have been dissatisfied with the quality of
reproduction with them.  One other thing you might try is to use either computer
averaging or a dsp technique to filter out the scanner noise.  However, this
will be difficult to do since the scanner is so loud.

One other thing that might be tried is the use of a steno microphone such as
court recorders use.  I've used them in classrooms and they do cut out a good
deal of outside noise.
