You must first antilog each … shovels pub hambletonWebThe decibel level of a sound having an intensity of 10 –12 W/m 2 is β = 0 dB, because log 10 1 = 0. That is, the threshold of human hearing is 0 decibels. Each factor of 10 in intensity corresponds to 10 dB. For example, a 90 dB sound compared with a 60 dB sound is 30 dB greater, or three factors of 10 (that is, 10 3 times) as intense. shovels pub blackpool menuWebCheck your headphone level while you listen.
