How would you produce 972 Hz?

Answer 1

That's just below musical note B5, so you could tune a piano string to that and relax it just a little. If you want an electrical signal at that frequency, use an audio signal generator or build an audio oscillator circuit. Use a digital counter to measure the frequency and make fine adjustments. Use a programmable audio source like the sound card on a computer. It all depends on what kind of signal you want, how accurate, and how pure.

Answer 2

Depends. What power level is required? What precision of frequency? What power source is available? What wave form is wanted? You could get a crystal cut to 32 x 972 Hz (watch crystals are about this frequency) and divide it by 32 to get a square wave at the specified frequency.

Answer 3

You could use a computer software that generates frequency Thu your computer speakers. The human ear can hear from 20 to 20000 Herts. In the old days they used a frequency generator to and amplifier to the speaker and a frequency generator receiver to check the tone. You could also check on download.com for free software or trial in order to generate your tone. You could also look for a Audio Test Cd Although it wont have that same frequency It would have one very close such as a 1,000 hertz.
