Bekeshi Audiometry

Bekesy audiometry is a hearing research method developed by the Hungarian biophysicist Georg von Bekesy (1899-1972).

The essence of the method is that the subject is presented with pure tones of different frequencies and intensities. The sound is supplied through headphones, and the volume level smoothly increases and decreases. During the procedure, the subject holds a special switch in his hand and notes the moments when he begins to hear the sound and stops hearing it.

These points are recorded on a paper tape moving at a constant speed. The result is a graph called an audiogram that shows hearing thresholds for each frequency. Using an audiogram, an audiologist can determine the presence and degree of hearing loss.

Bekesy audiometry allows you to obtain accurate and reproducible hearing test results and is still widely used in medical practice.

Bekeši, Peter (Hungarian Bekeši Péter; October 22, 1927, Budapest - June 30, 2014, London) - Hungarian-British biophysicist, engineer and entrepreneur, inventor of the audio measurement system.

Bekesy began his scientific career at the Technical University of Budapest. He worked in the fields of medicine, biology, physics and engineering, and was also involved in teaching. Bekesi has developed a new technology to measure electrical potential
