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...

If the decibel reading of a sound that is painful is 140 and the decibel reading of music played is 123, how much more intense is the painful sound than the music played? The intensity of painful sound is approximately times more intense than the other sound. Round to the nearest Integer as needed.)

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?
