Cutting out specific sound frequencies?

Question

is there any way to create a device that cuts out specific frequencies of sound only?

Answer 1

Yes, this is known as a band-pass filter. It's usually a tuned RLC circuit it can be readily made from a few parts from radioshack (or equivalent) or possibly laying around in garbage electronics near you.

Answer 2

Good answer silver; the only thing I would add is that software band pass filters typically come with most sound mixing software (in case you were looking for a digital solution).

Answer 3

I believe what you are looking for is a notch filter, not a bandpass filter. A bandpass filter passes a band of frequencies attenuating all frequencies outside of it's specific range. A notch filter (which is a band stop filter with a very narrow range) removes a narrow frequency band from a signal with a range as little as a few Hz. A typical application would be a 60 cycle hum filter which would remove only frequencies in the 59 to 61 Hz range, masking the hum while leaving the signal largely unchanged
