The threshold of hearing—the lowest-intensity sound a person can hear—depends on, among many factors, the frequency of the sound. During a hearing exam, the hearing specialist creates an audiogram, a graph of the patient’s hearing threshold (in dB) versus sound frequency; thresholds above 20 dB indicate hearing loss. For the audiogram shown in Figure P15.73, what is the ratio of the sound intensity (in W/m2) of the faintest sound the patient can hear at 1 kHz to that of the faintest sound she can hear at 6 kHz?

The sound of loudness of sound in the range of $15 \mathrm{~B}-16 \mathrm{~B}$ is (1) not audible (2) just audible (3) moderate (4) painful to the ear
