The decibel (dB) scale is logarithmic, not linear, increasing by a power of ten with every 10dB, which roughly equates to a doubling in loudness based on average human hearing. Consequently ...

A decibel, designated by the letters dB, is a logarithmic scale of loudness. Our ears detect changes in volume in a non-linear fashion. Sound loudness—which is not necessarily the same thing as ...

The PHON scale was devised to express this subjective impression of loudness, since the DECIBEL scale alone refers to actual sound pressure or sound intensity levels. Historically, the A, B, and C ...

Sound levels are measured on a scale known as the decibel \(dB\) scale. The higher the number the greater is the sound level. Too much noise can damage hearing. Exposure to 90 decibel sound levels ...

how the scale relates to common everyday sounds. Very basically, the decibel scale increases in factors of 10 – and more ...
