i am trying to make a clap circuit which uses 741op-amp with 9v battery, i think that these combinations can increase its sensitivity.....can you please help me in making a highly sensitive clap circuit?
Well, to be fair. I have a gaming headset with a mic on it which is probably no more than 3/16" in diameter and it can quite easily pick up sounds throughout my room even if I don't want it too. Of course, if I turn up the amplification on it, you can hear even more!
So instead of trying to build a microphone array, I think the better approach would be using a single decent quality microphone, a clean power supply, and a clean amplifier...
Of course, I say this because I do not have any hands on experience with a microphone array. All I can tell you is a related experience with a guitar pickups in which wiring them in series or parallel may make the instrument sound 'warmer'
