Amplifier Power Required
This calculator provides the required power output from the
amplifier to produce a desired Sound
Pressure Level (SPL) at a given distance, along with an amount of headroom to
keep the amplifier(s) out of clip.
Example: You are designing a system where the
farthest listening position from the loudspeaker is 100 meters, and the desired
Sound Pressure Level is 85 dB SPL The loudspeaker chosen for the job has a
sensitivity rating of 95 dB. With the minimum recommended amplifier headroom of 3
dB, you need to choose an amplifier that can supply at least 1,995 watts
to the loudspeaker.
This form requires a Microsoft Internet
