If I am testing your sound absolute threshold what percentage of the time must you hear the minimum stimulus in order for the absolute threshold to have been found?

A	30%
B	100%
C	25%
D	50%

Explanation:

Detailed explanation-1: -Absolute Threshold-minimum intensity of a stimulus that one can detect 50% of the time.

Detailed explanation-2: -The sensitivity of a given sensory system to the relevant stimuli can be expressed as an absolute threshold. Absolute threshold refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time.

Detailed explanation-3: -An absolute threshold is the smallest amount of stimulation needed for a person to detect that stimulus 50% of the time. This can be applied to all our senses: The minimum intensity of light we can see. The lowest volume of a sound we can hear.

Detailed explanation-4: -Absolute Threshold: the minimum stimulation needed to detect a particular stimulus 50 percent of the time.

Detailed explanation-5: -Absolute threshold is measured across several trials. It is the lowest or weakest level of stimulation (e.g., the slightest, most indistinct sound) that can be detected on 50% of trials.
