децибел(One tenth of a bel (named after Alexander Graham Bell), a unit used in electronics and other fields to measure the strength of a sound or signal. Decibel measurements fall on a logarithmic scale and compare the measured quantity against a known reference)
децибел(unit of sound intensity, loudness, or pressure level; 0.0002 microbars of pressure equals 0 db sound-pressure; единица измерения силы (интенсивности) звука, громкости или уровня давления; давление 0.0002 микробар равно давлению звука 0 дБ); дБ(unit of sound intensity, loudness, or pressure level; 0.0002 microbars of pressure equals 0 db sound-pressure)
