Re: Mike element
Yes, you have it right.toggle quoted messageShow quoted text
For a given sound pressure into the mike,
the -24 dB mike creates a voltage that is 10 times bigger than the -44 dB mike.
A 10 times bigger voltage into a fixed resistance means 100 times more power,
since power in watts = volts * amps = volts * volts/ohms.
With 100 times more power, that's 10 * log(100) = 20 dB more power.
If the mike were zero dB, we'd get 1 volt from the mike.
Since the voltages we are dealing with are less than one volt,
we get negative numbers when representing the values in dB.
