The Audiogram. As recommended in the ANSI S3.21-1978 (R.I 986) "Methods for Manual Pure-Tone Threshold Audiometry, the audiogram shall be shown as a grid with frequency, in Hertz (Hz), represented logarithmically on the abscissa and hearing level (HL), in decibels (dB), represented nearly on the ordinate. To carry out pure tone audiometry testing, HCPs simply need to provide a quiet environment, headphones, a recording of appropriate sounds and audiograms to record the results. Low cost As minimal equipment is required to conduct pure tone audiometry testing, they are a relatively low-cost way to assess an individual’s hearing function.

The threshold of hearing is plotted relative to a standardised curve that represents 'normal' hearing, in dB(HL).

Pure-tone signals are delivered to the ear via air conduction and bone conduction at a variety of frequencies, and the patient responds to the sound by signaling the examiner with a button or by raising a hand. An audiogram is a document that we use in Practice to take a record of a hearing test.

Pure tone audiometry charts the hearing level of different tone frequencies in both ears. On an audiogram chart, red O's The simplest way to test hearing is called pure tone audiometry. The air conduction and bone conduction hearing levels on the audiogram can tell us a lot Hearing healthcare professionals rely on the audiograms produced through pure tone audiometry, among other tests, to diagnose and treat hearing loss. Get tested for Audiometry / Audiography / Audiology / Audiogram Test at home The most popularly use method is the pure-tone audiometry which measures In pure tone audiometry for both air conduction and bone conduction it is possible that responses obtained are those of the non-test ear. Rationale. To establish On pure tone audiogram, the air conduction hearing level is classified as the flat type and the type in which the threshold of the high pitch area is reduced when It tells us the type and degree of hearing loss. The results of the hearing test (pure tone audiometry) are plotted on an audiogram.
