Do you think that the volume control on an audio amplifier is calibrated in intensity or intensity level? In other words, if you turn your stereo half way down, have you cut the power in half or cut the decibel level in half? Explain

the intensity is reduced

Explanation:

In electronic equipment, the volume is controlled by the power supplied to the speakers, the power is given by the formula

         P = V I

In general, it is easier to control the voltage =, as important as this is a linear relationship, so by lowering the selector the controlled variables V or I decreases by half, so the intensity decreases at half.

In summary the intensity is reduced

the answer would be a
