[Tinnitus measurement with conventional audiometer versus high-frequency audiometer].
INTRODUCTION AND OBJECTIVES Determinations of the psychoacoustic characteristics of tinnitus (frequency and intensity) are valid for diagnosis, treatment, monitoring and research purposes. The aim of this work is to compare the frequency of the tinnitus measured with a standard audiometer and a high frequency audiometer. METHODS We used a conventional audiometer (frequency range: 125-12,000 H...
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 کاملClinical validation of the AMTAS automated audiometer.
OBJECTIVE To validate the air- and bone-conduction AMTAS automated audiometry system. DESIGN Prospective study. Test-retest reliability was determined by assessing adults with AMTAS air- and bone-conduction audiometry. Accuracy was determined by comparing AMTAS and manual audiometry conducted on adults. AMTAS testing was conducted in a quiet room and manual audiometry in a sound booth. STUD...
متن کاملAn Improved WAGNER-WHITIN Algorithm
We present an improved implementation of the Wagner-Whitin algorithm for economic lot-sizing problems based on the planning-horizon theorem and the Economic- Part-Period concept. The proposed method of this paper reduces the burden of the computations significantly in two different cases. We first assume there is no backlogging and inventory holding and set-up costs are fixed. The second model ...
متن کاملA noise-attenuating enclosure for audiometer earphones.
Noise-excluding earphones may be subdivided into circumaural earphones and noise-attenuating earphone enclosures. Two versions of 'Otocups', an example of the latter subdivision, were evaluated in a series of experiments and in comparison with a conventional type of earphone (Telephonics TDH-39 receiver in a MX-4I /AR cushion). The experiments involved a comparison of auditory threshold, artifi...
