WebThe -3dB point is also known as the "half power" point. In voltage it may not make not make tons of sense as to why we use ( 2 / 2 ), but lets look at an example of what it means in the sense of power. First off, P = V 2 / R, but lets assume R is a constant 1 Ω. Because of the constant 1ohm, we can remove it from the equation all together. WebTo perceive a doubling of volume you need the measured sound pressure level to increase by 10dB. You need an amplifier with 10x the electrical output power (ie; 50W up to 500W) to achieve that.
