Final answer:
The amplitude and frequency of a sound wave in the healthy ear are related to attributes of sound perception. Hearing tests measure the threshold of hearing at different frequencies to detect any hearing loss.
Step-by-step explanation:
The amplitude and frequency of a sound wave are both related to the attributes of sound perception in the healthy ear. Amplitude refers to the intensity or loudness of the sound, while frequency refers to the pitch or tone of the sound. In the healthy ear, the sensitivity to different frequencies varies, with higher frequencies being more difficult to perceive as we age. Hearing tests measure the threshold of hearing at different frequencies, helping identify any hearing loss.
