Definition: Dbm1 (dB: decibels) is a measure used to represent the loudness level of sound, with each dB representing 3DB higher than 70dB. Definition: - It's a unit of measurement that compares the loudness or intensity of sound. It measures the ratio between the amplitude at two specified points. - In general, 100dB (dB) is equal to 20 times the difference in pressure levels at two points on an ideal voltmeter. - 1 dB is the same as a standard deviation level; it shows how far away something is from being "normal" or normal frequency. Example: Dbm1 = 100dB. This means the sound level was 20 times as loud compared to what it would've been had it been at a pressure level of 70dB.
