9. Sound levels are measured by the logarithmic decibel scale, named after Alexander Graham Bell. The sound level, L, corresponding to an intensity of I, in watts per square metre, is し= 10 log-, where lo is the minimum intensity audible to the human ear. If amplified rock music has a loudness of 120 dB and ordinary conversation has a loudness of 50 dB, how many times louder than ordinary conversation is amplified rock music?

The decibel scale is a logarithmic scale for measuring the sound intensity level. Because the decibel scale is logarithmic, it changes by an additive constant when the intensity as measured in W/m2 changes by a multiplicative factor. The number of decibels increases by 10 for a factor of 10 increase in intensity. The general formula for the sound intensity level, in decibels, corresponding to intensity I is β=10log(II0)dB, where I0 is a reference intensity. For sound waves, I0 is taken...

The decibel rating D| is related to the sound intensity I| by the formula D = 10 log_10 (I/10^-16)| for the noise level in decibels. Let D| and d| represent the decibel ratings of sounds of intensity I| and i|, respectively. Using properties of logarithms, find a simplified formula for the difference between the two ratings, D-d|, in terms of the two intensities I land i|. help (logarithms) (Enter log10 or logten for the base 10 logarithm.) If a sound's...
