The loudness, l, measured in decibels (db), of a sound intensity, i, measured in watts per square meter, is defined as l = 10 log startfraction i over i 0 endfraction, where i 0 = 10 superscript negative 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 mower?
brandon’s sound intensity is one-fourth the level of ahmad’s mower.
brandon’s sound intensity is one-fourth the level of ahmad’s mower.
brandon’s sound intensity is 20 times the level of ahmad’s mower.
