AUDITORY THRESHOLDS Meaning and
Definition
-
Auditory thresholds refer to the minimum intensity or level of sound required for an individual to detect or perceive a sound stimulus. It is a measure of the sensitivity of the human auditory system to different sound frequencies. These thresholds vary from person to person and are commonly determined through hearing tests.
The auditory threshold can be measured using various techniques, such as pure-tone audiometry. During this test, individuals are presented with sounds of varying frequencies and intensities, and they signal when they can first hear the sound. The lowest level at which they can consistently detect the sound is known as their auditory threshold.
The auditory threshold is typically expressed in decibels (dB), which quantifies the sound intensity. It is crucial in diagnosing hearing impairments and evaluating the severity of hearing loss. Individuals with normal hearing typically have auditory thresholds around 0 dB, meaning they can hear very faint sounds. However, individuals with hearing loss may have elevated auditory thresholds, requiring louder sounds for detection.
Understanding auditory thresholds is essential in various fields, such as audiology, psychoacoustics, and noise control. It helps to determine the minimum sound levels needed for speech comprehension, the effects of loud noise exposure on hearing, and the design of hearing aids and assistive listening devices. By assessing auditory thresholds, healthcare professionals can diagnose and manage auditory disorders, improve communication strategies, and enhance the overall quality of life for individuals with hearing difficulties.

Etymology of AUDITORY THRESHOLDS
The word "auditory" comes from the Latin word "audire", which means "to hear". The term "threshold" originated from the Old English word "threscold", which refers to the plank or beam placed under a door to keep dirt or drafts out. In a metaphorical sense, it signifies the point at which something begins or changes. Therefore, "auditory thresholds" refers to the point or level of sound intensity at which a person can start to perceive or hear sounds.
