Definition: The hearing threshold is the sound level below which a person’s ear is unable to detect any sound. For adults, 0 dB is the reference level. A threshold shift is an increase in the hearing threshold for a particular sound frequency. It means that the hearing sensitivity decreases and that it becomes harder for the listener to detect soft sounds.

Threshold of Hearing the minimum sound pressure level at which a sound of a given frequency can be perceived by the human ear. It is customarily expressed in decibels by taking as the zero level a sound pressure of 2 X 10-5newton/m2, or 2 × 10-4dyne/cm2, at a frequency of 1 kilohertz (for a plane wave). Figure 1.

Hearing thresholds are defined as the lowest level sound that can be heard 50% of the time. The decibel (or dB) is the unit of intensity used to describe hearing sensitivity. During a diagnostic hearing evaluation the threshold is measured at different frequencies (or Hertz, Hz) in each ear.

An absolute threshold is the smallest level of stimulus that can be detected, usually defined as at least half the time. The term is often used in neuroscience and experimental research and can be applied to any stimulus that can be detected by the human senses including sound, touch, taste, sight, and smell.

Standard Threshold Shift (STS) is a significant change in the hearing ability of a person in one or both ears of an average of 10 decibels (dB) or more at 2000, 3000, and 4000 hertz (Hz). STS is defined in the occupational noise exposure standard at 29 CFR 1910.95 (g) (10) (i). Safeopedia Explains Standard Threshold Shift (STS)

OSHA STS: in either ear, a change of 10 dB or more in the average of hearing thresholds at 2000, 3000, and 4000 Hz. OSHA STS TWICE: in either ear, a change of 10 dB or more in the average of hearing thresholds at 2000, 3000, and 4000 Hz is present on one annual audiogram and is persistent in the same ear on the next audiogram.
