2. Loudness is a physiological sensation sensed by the brain. Loudness varies nearly as the logarithm of intensity. The unit of intensity for sound is the decibel (dB) named after Alexander Graham Bell, inventer of the telephone. Referencing the table below listing some common sources and sound levels answer the following questions: a) What is the difference in decibels between the sound level of a close whisper and busy street traffic? b) By what factor is the sound intensity of the busy street than that of the close whisper? c). How much more intense is normal speech than a close whisper ? d). How much more intense is the threshold of pain than busy street traffic. e) The signal to noise ratio for a tape recorder is listed at 50 dB, by what factor is the sound intensity of the music greater than that of the noise?
