Amplifier Power Vs Room Size Calculator
Enter the following details to calculate the estimated wattage for your amplifier:
The ideal amplifier wattage for the perfect room is based on the room size and the speaker sensitivity, if you are in doubt about the amplifier wattage? Which amplifier can I use in my bedroom or hall? The perfect amplifier wattage calculator based on the room measurement is here.
To identify the perfect watts for the room is calculated using a different formula. To calculate you need to find the following details.
- Calculate room volume
- Estimate speaker sensitivity
- Determine desired sound level
- Calculate wattage
Calculate room volume
You need to measure the room dimensions and enter the values in the calculator app given above all values need to enter in feet.
Estimate speaker sensitivity
The speaker sensitivity is measured using decibel (dB). This means at a certain wattage the power is getting a certain distance. Example if 88dB means that at 1 meter with 1 watt power, it produces 88dB sound.
Determine desired sound level
This is determine the how much loud of sound you want. The normal range is about 80 to 90dB.Â
Calculate Amplifier power vs Room size
The wattage of the amplifier for the required room space is calculated using this formula:
Watt = 10^(desired dB – speaker sensitivity+1*log10(room volume))/10
