[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 کاملHigh-Frequency Hearing
Glossary: Azimuth – direction along the horizon relative to a listener Δt – difference in the time of arrival of a sound at the two ears Δfi – difference in the frequency-intensity spectra of a sound at the two ears Functional head size – the time it takes for sound to travel around the head from one ear to the Octave – an interval between two frequencies that have a 2 to 1 ratio (.25 kHz to .5...
متن کاملFrequency difference limens at high frequencies for normal-hearing and hearing-impaired subjects
The smallest detectable change in frequency of a pure tone (the difference limen for frequency, DLF, expressed as ∆f/f) may depend on two mechanisms: a place mechanism based on the filtering within the cochlea [1] and a temporal mechanism based on the patterns of phase locking in the auditory nerve to the “temporal fine structure” (TFS) evoked by the tone [2]. The precision of phase locking wea...
متن کاملSample discrimination of frequency by hearing-impaired and normal-hearing listeners.
In a multiple observation, sample discrimination experiment normal-hearing (NH) and hearing-impaired (HI) listeners heard two multitone complexes each consisting of six simultaneous tones with nominal frequencies spaced evenly on an ERB(N) logarithmic scale between 257 and 6930 Hz. On every trial, the frequency of each tone was sampled from a normal distribution centered near its nominal freque...
