Auditory Fatigue and Changes in Audiometer Pen‐Excursion Size

[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...

/JRt-*- ~7Sr Free Voice and Pure Tone Audiometer for Routine Testing of Auditory Acuity

Pure 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 ...

Estimation of Maximum Inclusion Size and Fatigue Limit in HSLA-100 Steel

The objective of the current study is to determine the fatigue limit of a clean and high-performance material named as HSLA-100 steel and to compare the obtained fatigue limit with that of theoretically predicted fatigue limit by statistics of extreme value (SEV) method. Also, the size of inclusions located at the site of fatigue crack nucleation on the fracture surface of the fatigue test spec...

Auditory thalamus neurons during sleep: changes in frequency selectivity, threshold, and receptive field size.

The present study describes how the frequency receptive fields (RF) of auditory thalamus neurons are modified when the state of vigilance of an unanesthetized animal naturally fluctuates among wakefulness (W), slow-wave sleep (SWS), and paradoxical sleep (PS). Systematic quantification of several RF parameters-including strength of the evoked responses, response latency, acoustic threshold, sha...
