Definition - What does Baseline Audiogram mean?
A baseline audiogram, in audiometric testing, provides a static reference point for future audiometric tests for a specific individual and lets a trained medical professional document any changes in hearing capabilities over time. It is used to monitor whether or not an employee's hearing level is decreasing or being maintained, so that any hearing loss can be detected early.
WorkplaceTesting explains Baseline Audiogram
A baseline audiogram is the result of an initial audiometric test that is performed in order to achieve a reference level of a person's hearing. This is used as a point of reference to be compared to future audiometric testing in order to determine if an employee's hearing is deteriorating. An employee's hearing may be negatively affected when continually exposed to loud noise while at his/her workplace. This is especially likely if the employee does not consistently wear appropriate hearing protection. Baseline audiograms are typically produced during the pre-employment stage of hiring, in order to get an accurate level of the person's hearing before they are exposed to any loud noises while in the company's employment.
