The loudness, l, measured in decibels (db), of a sound intensity, i, measured in watts per square meter, is defined as l=10logl/l^0, where l^0=10^-12 and is the least intense sound a human ear can hear. brandon is trying to take a nap, and he can barely hear his neighbor mowing the lawn. the sound intensity level that brandon can hear is 10-10. ahmad, brandon’s neighbor that lives across the street, is mowing the lawn, and the sound intensity level of the mower is 10-4. how does brandon’s sound intensity level compare to ahmad’s?
