Did you know?
WebThe dynamic range of the auditory system, which is the interval between the softest and loudest sounds that the ear can hear, is more than 120 decibels. The decibel is the log of the ratio of two quantities multiplied by 10. This means that the ear can hear sounds whose strength lies anywhere within a range of over 12 orders of magnitude. WebA-weighted decibels (dBA, or dBa, or dB(a)): A-weighted decibels, abbreviated dBA, or dBa, or dB(a), are an expression of the relative loudness of sounds in air as perceived by the human ear. In the A-weighted system, the decibel values of sounds at low frequencies are reduced, compared with unweighted decibels, in which no correction is made ...
