refers to the level of a pure tone of a given frequency that is minimally detectable by a person with normal hearing. For example, the for a 1-kHz pure tone is 7.5 dB SPl.

Audiometric Zero simply means the threshold of hearing. It is the lowest intensity at which a normal person can hear a sound. The audiometric zero varies from person to person. Thus the International Standards Organization (ISO) has defined it as “audiometric zero is the mean value of minimal audible intensity in a group of normally hearing healthy young adults.’’

The zero level on the audiogram is an arbitrary sound pressure level which indicates ideal normal hearing in young adults. Figure 133.1 Audiometry results. The right ear shows thresholds that are within normal limits for air and bone conduction. The left ear shows a mixed hearing loss.

A method of testing the hearing of children who cannot be adequately tested by conventional means. The test is based on the electroencephalogram's being altered by perceived sound without the need for a behavioral response; therefore, the test may be done on an autistic, severely retarded, or hyperkinetic child who is asleep or sedated.

Basic definition. If an employee’s hearing test (audiogram) reveals that the employee has experienced a work-related Standard Threshold Shift (STS) in hearing in one or both ears, and the employee’s total hearing level is 25 decibels (dB) or more above audiometric zero (averaged at 2000, 3000, and 4000 Hz) in the same ear (s) as the STS, then the case must be categorized as …
