Though the word is used by Hughes (p. 58), it was coined by the British physician Benjamin Ward Richardson (1828-96), who concludes a report following Hughes' article in the same journal ("Some Researches with Professor Hughes' New Instrument for the Measurement of Hearing; the Audiometer,...
Even though audiometers can be constructed with precision, the nature of hearing acuity measurement is such that the results from successive tests on the same individual may vary by several decibels at a given frequency. When it is necessary to screen a large number of personnel or to monitor ...

It is best used in conjunction with tympanometry and measurement of stapedius reflex thresholds. The PTA involves the measurement of the threshold of hearing, i.e., the lowest intensity at which sound can just still be heard across a range of frequencies audible to the human ear. It is a...
2. Test is performed using audiometer, headphones, insert earphones or sound fields. 3. A pure tone (single frequency) is passed to the ear through an earphone and the lowest intensity at which this tone is perceived 50% of the time is measured in decibels (dB). This measurement is calle...
