The noise rating of an air conditioner is 50 decibels, and the noise rating of a washing machine is 65 decibels. determine how many time greater the washing machine's intensity of sound is. use the formula , β = 10log i/i 0 where β is the sound level in decibels, i is the intensity of sound you are measuring, and io is the smallest sound intensity that can be heard by the human ear (roughly equal to 1 x 10^-12 watts/m2). the washing machine's intensity of sound is (blank) times greater than that of the air conditioner.
