Sentence examples for threshold of hearing from inspiring English sources

These determine the threshold of hearing.

Hence, the outer and middle ear transfer functions limit the ability to detect low-amplitude audio signals and affect the absolute threshold of hearing [24, 25].

According to the frequency response of the outer and middle ears, the absolute threshold of hearing tend to be lowest in the 2-3 kHz band and increases with increased or decreased frequency.

Ultrasound is defined as pressure waves with a characteristic frequency greater than 20 kHz, the nominal upper threshold of hearing for humans.

That level was increased during testing by an extra 3 dB to provide some extra margin for detecting speech at levels that may be close to the threshold of hearing.

The dynamic range between the threshold of hearing and loudness discomfort level is around 100 dB in normal hearing listeners.

These variables included age, gender, aided soundfield average hearing thresholds, duration of hearing loss, duration of hearing aid use, and aided SRTs obtained in quiet and in noise as a composite score.

In order to identify the optimum threshold for discrimination of hearing loss, we computed the d-prime (d'), the distance from the diagonal in an ROC curve over a range of criteria values for hearing impairment (10 50 dB HL in 1 dB increments).

This impairment was not related to the increase in hearing thresholds, as performance on speech audiometry was remarkably poorer compared to control subjects showing cochlear hearing loss and a comparable amount of hearing threshold elevation.

Although the measurement of hearing thresholds from each ear separately appears a relatively straightforward procedure, sound may cross from one side of the head to the other.

Such statistical approaches are weakened by the variability of hearing thresholds in young mice and the inconsistent timing of degenerative effects in older mice.
