How to measure sound? Fo science Fair experiment....?
So I designed a music laser transmitter. It has a laser and some other things connected to an iPod for the transmitter and the receiver is a solar cell with some stuff attached to an iHome. It plays, now I have to measure the sound levels when I add distance. How can I measure this without a decibel meter? Is it possible a guitar tuner could substitute in? Please help! Thanks:)
A scope is the best choice. Or you can use a microphone,an ampilfier and one AC voltmeter connect to the speaker. Adjust the level of amplifier until you see voltage reading at the speaker when microphone receives AF signal. Keep this setting to compair a new reading when it receives a weaker signal.
