Links to PubMed are also available for Selected References. Pure tone audiometry An audiogram (Figure 1) is a graphic re-presentation of a hearing test. With a pure tone test, it is called a pure tone audio-gram. It is usually drawn in graphic form, with the frequencies of the signals presen-ted on the horizontal axis (Hertz / Hz) and the intensities of the signals on the vertical axis (decibels / dB).
It is also used in various kinds of audiometry, including pure tone audiometry, and the standard hearing test to test each ear unilaterally and to test speech recognition in the presence of partially masking noise. Auditory masking is exploited to perform data compression for sound signals . … 03/04/2018 · This is called the masking dilemma, this occurs when there is a moderate to severe bilateral conductive hearing loss. In this case, masking noise intensity presented in the non-test ear crosses over to the test ear and elevates the thresholds. This means that you will keep masking without reaching the plateau, hence the dilemma.

1.2.1 Method of Audiometry Auditory sensitivity may best be ascertained by the use of an audiometer, which is an electronic oscillator capable of emitting pure tones over a wide range. The examinee is seated in a soundproof room and fitted with a set of earphones to measure his/her threshold (slightest perceptible sound) for pure tone. Audiometry consists of tests of function of the hearing mechanism. This includes tests of mechanical sound transmission (middle ear function), neural sound transmission (cochlear function), and speech discrimination ability (central integration). A complete evaluation of a patient's hearing must be done by trained personnel using instruments designed specifically for this purpose.

In bone conduction tests, the untested ear should always be excluded by an air conducted masking sound. Appropriate masking levels must be determined during the course of the test by Zwislocki method and the maximum usable masking level should not be exceeded during the tests.
