Web27 de ago. de 2024 · Overview. Pure-tone audiometry is a behavioral test used to measure hearing sensitivity. This measure involves the peripheral and central auditory systems. 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 displaying ... Web14 de jul. de 2024 · Throughout much of the history of audiology there have been a wide range of attempts to define “normal” hearing (eg, see the historical review by Kryter 1). For a variety of reasons, including simplicity and reliability of measurement as well as association with speech communication, these definitions were based on air-conduction … Web10 de fev. de 2024 · Take the acoustic reflex threshold at 500Hz or 1000Hz in the ear you want to test and add 10dB. This is the stimulus level you will use for testing (e.g., if the reflex threshold was 80dB at 1000Hz, you would test at 90dB at 1000Hz). The intensity is set automatically 10dB above the found reflex. tsw 17 wheels
