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?
