纯音测听是测试听敏度的、标准化的主观行为反应测听,它包括气导听阈和骨导听阈测试。什么是听阈?听阈是听觉的最小声强值(以分贝为单位),是在规定条件下给一定次数的信号,受测者对其中50%能作出刚能听及反应时的声级。纯音听阈测试即...

OBJECTIVE: Our purpose was to evaluate performance of the children on pure tone audiometry (PTA), and role of age, concentration level (CL) and otitis media with effusion (OME) in testing process. METHODS: This study was prospectively performed on 100 consecutive children referred for PTA ...
Pure tone audiometry is used for testing our hearing level. Types of testing are air conduction testing and bone conduction testing.
Pure tone audiometry Masking Theoretical model Mathematical simulation Japanese “ABC” method Evaluation of masking method 1. Introduction Pure tone audiometry is the most basic test in audiological medicine. To properly estimate audiological thresholds, “masking” of the non-tested (contralateral) ea...
Pure-tone audiometry is a behavioral test used to measure hearing sensitivity. This measure involves the peripheral and central auditory systems.
What is audiometry ●Threshold Measures●Pure Tone:○Air & Bone●Speech●Behavioral Testing Threshold least amount of sound necessary for a signal to be detected 50% of the time Pure tone -single frequency tone-250-8000 Hz Air conduction what frequencies do we test it at? 250-8000 Hz Bone...

conduction audiometry, the masking noise is presented through the earphone opposite to the ear being tested. In bone conduction audiometry, the usual procedure is to deliver the masking noise via an insert earphone. Narrow-band noise centered on the frequency of the test tone is most effective....
