When Anita went to her doctor, he gave her a hearing test. During the test, the doctor presented tones to Anita through earphones. The tones started at a low intensity and then became louder. After Anita could hear the sound, the doctor asked Anita to raise her hand whenever she heard the sound increase in volume. The doctor was testing Anita's .

When Anita went to her doctor, he gave her a hearing test. During the test, the doctor presented tones to Anita through earphones. The tones started at a low intensity and then became louder. After Anita could hear the sound, the doctor asked Anita to raise her hand whenever she heard the sound increase in volume. The doctor was testing Anita's absolute threshold

Explanation:

Absolute threshold is the minimum amount of energy that a person can detect (Lowest level that a person will feel sensation) . It is basically the minimum stimulation needed to detect a stimulus 50% of the time. Something that is below this absolute threshold is subliminal.

As in the given scenario, Anita was giving her hearing test, tones were presented to her by the doctor,the tones started at a low density and then became louder, the doctor was actually testing the minimum amount of sound that she can hear. hence, doctor was testing Anita's absolute threshold

ABSOLUTE THRESHOLD

The doctor was testing Anita's absolute threshold.

Explanation: The absolute threshold or absolute threshold of hearing (ATH) is the lowest level of sound of a pure tone that an average ear of an individual with normal hearing can hear with no other sound present.It is the lowest level of pure tone that an individual can detect, considering that the individual have normal hearing and has no interfering sounds.

The standard threshold of hearing at 1000 Hz is nominally taken to be 0 dB, but the actual curves show the measured threshold at 1000 Hz to be about 4 dB.

For example, you might not be able to hear someone whispering from 30 feet away, but if that person speaks to a normal voice, it may reach your absolute threshold.
