What is the name of the bracketing technique used in hearing tests?

The Hughson/Westlake technique is a method utilized in hearing tests to determine an individual's hearing threshold. This procedure employs a bracketing approach where the tester presents tones at various intensity levels. The testing begins above the expected threshold and gradually decreases to find the lowest level at which the individual can consistently respond to the signal. It then continues to adjust intensity levels, alternating between ascending and descending frequencies, allowing for a more accurate determination of hearing sensitivity.

This technique is favored because it minimizes the variability in responses and provides a clear understanding of the hearing abilities of an individual. The bracketing method helps ensure that the threshold identified reflects the true hearing sensitivity rather than fluctuations or chance responses.
