As noted above, a logarithmic scale is used to measure sound intensity in decibels rather than a linear scale. Decibel strength grows very fast rather than each increase being directly ...

UB undergraduates measure the sound-intensity levels around the North Campus for a physics of music course.

In acoustics, sound intensity is measured in decibels. The decibel level is 10 times the log of the ratio of energy to that of a very weak sound known as the threshold of hearing.

Sound Intensity A measurement of sound power level does not vary with distance from the sound source. By analogy, a 75-watt light bulb always has a power level of 75 watts. It does, however, appear ...

SPL may be measured with a SOUND LEVEL METER weighted according to a specific frequency response pattern and termed SOUND LEVEL. The electroacoustic equivalent to SPL is measured with a VU METER.
