Method and Device for Conducting a Pure Tone Audiometry Screening

摘要

A method for conducting a pure tone audiometry uses tones of different frequency and intensity utilizing an adaptive procedure. Tone signals with at least two different frequencies are independently changed by delivering to a test person a set of at least three different test stimuli selected from a group of no tone at all, one long tone with a first frequency, and a multitude of short tones of a second frequency. The second frequency is higher than the first frequency. The test person's response corresponds to one of the different test stimuli, and a next test stimulus is presented to the test person after a short delay. A device for conducting an automated pure tone audiometry screening includes a tone generator capable of delivering pure tones of different frequencies and intensities and is able to deliver tones either as a long tone or a set of shorter tones.
