Pure tone: A single frequency sound. 2. Audiometer: Equipment used to generate pure tones of varying frequency and loudness and control their presentation. 3. Air conduction (AC) threshold: lowest level dB HL (hearing threshold) at which the subject perceives 50% of pure tones introduced via earphones or speakers. Pure-tone audiometry is broadly defined as either screening or threshold search: Screening audiometry presents tones across the speech spectrum (500 to 4,000 Hz) at the upper limits of normal hearing (25 to 30 dB for adults, and 15 to 20 dB for children) 4). Results are recorded as pass, indicating that the patient’s hearing levels are within normal limits, or refer, indicating that hearing loss is possible and a repeat screening test or a threshold search test is recommended.

Pure-tone thresholds (PTTs) indicate the softest sound audible to an individual at least 50% of the time. Hearing sensitivity is plotted on an audiogram, which is a graph 2020-11-27 · The Hearing Test: Pure Tone Audiometry. The hearing assessment uses a battery of tests to ascertain your hearing abilities. The first and perhaps most fundamental test is pure tone audiometry. This test requires you to wear specially calibrated headphones and subsequently a specially calibrated bone conductor (which vibrates sounds through the The second was the Guidelines for Identification Audiometry (1975), adopted by ASHA in November 1974. The third was the Manual Pure-Tone Threshold Audiometry Guidelines (1976), adopted by ASHA in November 1977. ASHA encourages the professional community to use these guidelines.

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). Pure-tone audiometry requires a quiet testing environment with low levels of background noise. Background noise can cause elevated thresholds, especially in low frequencies ( eFigures 1A and 1B ).

One side of the graph represents frequency or pitch, and the other represents intensity, or decibels (dB). The marks on the graph show the softest sound the person could hear at each frequency.
