17 Aug 2020 A tone audiogram ( pure tone audiogram ( RTA ), hearing curve or audiogram for short ) is created by measuring the subjective hearing ability 


The horizontal axis of the audiogram represents sound frequency or pitch measured in Hertz (Hz). Sound frequency increases gradually the further one moves to the right along the axis. This movement can be compared to playing on the left side of a piano and gradually moving to the right side where the tone becomes more and more high-pitched.

An audiogram is the graphical representation of the results of pure-tone air conduction tests. Vertical lines represent the testing frequencies, arranged from low-pitched on the left to high-pitched on the right. Horizontal lines represent the loudness, from very soft at the top to very loud at the bottom.

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 … PURE TONE AUDIOMETER It is the electronic device used for creating pure tone audiogram. It consists of an audio-oscillator which generates pure tone sounds of different frequencies. Each tone can be separately amplified to a maximum of 100 to 110 dB in most frequencies except very low & very high frequencies. Audiometer is connected to standard & specified bone conduction vibrator or earphones As its name suggests, a pure tone hearing test uses pure tones to determine if a person can perceive every frequency in the audible spectrum. This type of hearing test is classed as a subjective test and is carried out using a device called an audiometer. The audiometer registers the results in an audiogram and reveals if your hearing is Uses of Pure Tone Audiogram • It is a measure of threshold of hearing by air and bone conduction and thus the degree and type of hearing loss.

The shape of the audiogram resulting from pure-tone audiometry gives an indication of the type of hearing loss as well as possible causes. Conductive hearing loss due to disorders of the middle ear shows as a flat increase in thresholds across the frequency range. Sensorineural hearing loss will have a contoured shape depending on the cause.
