Pure Tone Audiometry
Pure tone audiometry is the standard behavioral assessment of an individual’s hearing. The results of pure tone audiometry are recorded on a chart or form called an audiogram. In most cases a pure tone audiogram is easy to obtain and provides information about peripheral hearing acuity across the frequencies used in speech. It allows for a quick view of how well, or how poorly, an individual ca...
متن کاملPure Tone Audiometer
Estimation of pure tone hearing threshold is a part of hearing tests conducted in order to know the sensitivity of the human auditory system. This paper presents manual audiometer implemented in Matlab which can be used to conduct such measurements. Audiometer was calibrated by means of an artificial ear and pistonphone. Modified Hughson-Westlake method [1] usually used in manual audiometry is ...
متن کاملOff-response to pure tone burst is affected by the previous pure tone intensity
The auditory magnetic brain response, N1m, which is defined as a magnetic deflection occurring about 100 ms after the tone onset, varies depending on the stimulus interval. Hari et al. [1] measured the N1m responses to the onset of a 0.55-s white noise burst with four Stimulus Onset Asynchrony (SOA: 1.1, 2.2, 4.4, and 8.8 s) in different blocks. The results of their experiments indicated that t...
متن کاملDistribution characteristics of normal pure-tone thresholds.
OBJECTIVE This study examined the statistical properties of normal air-conduction thresholds obtained with automated and manual audiometry to test the hypothesis that thresholds are normally distributed and to examine the distributions for evidence of bias in manual testing. DESIGN Four databases were mined for normal thresholds. One contained audiograms obtained with an automated method. The...
متن کاملTheory and practice of pure tone audiometry
Pure tone audiometry indicates what hearing thresholds (dB) are required to just be able to perceive a tone at different frequencies (Hz). A pure tone audiology threshold at a specific frequency is the decibel level at which a sound is perceived 50% of the time. The decibel scale used in pure tone audiometry is dB Hearing Level (dB HL). The dB HL intensity scale is based on normal human hearing...
