SummarySound and ultrasound emitted by industrial ultrasonic (Uls) devices exceed the known proposed hygienic limits, especially for frequencies 10–20 kHz. The consequence of this may be a negative influence of this energy on the auditory function in the high-frequency hearing range. To determine the hearing risk to Uls operators, an adequate method for testing the hearing threshold from 10-20 kHz has been developed. In order to get reference values, 189 non-exposed persons were tested. On this…

Apart from the observed threshold elevation, the fraction of ears responding to acoustic stimuli at the highest frequencies decreases by about 10% with frequency increase of 1 kHz in the range of 13 to 19 kHz, which indicates that the hearing organ is more susceptible to high-frequency noise at thehighest hearing frequencies.

High-frequency hearing thresholds: effects of age, occupational ultrasound and noise exposure

Age was the primary predictor, and noise and ultrasound exposure the secondary predictors of hearing thresholds in the high-frequency range, and the results suggest that HFA could be useful in the early diagnosis of noise-induced hearing loss in younger groups of workers.

Damage to human hearing by airborne sound of very high frequency or ultrasonic frequency

This literature review examines the audiological, occupational hygiene and industrial safety literature on the subjective and auditory effects of audible sound in the very high frequency range and also in the inaudible ultrasonic range to suggest exposure limits for occupational noise exposure assessments.

Hearing status of people occupationally exposed to ultrasonic noise

Both EHFA and DPOAE seem to be useful tools for recognizing early signs of hearing loss among ultrasonic device operators.

The Hearing Threshold of Employees Exposed to Noise Generated by the Low-Frequency Ultrasonic Welding Devices

It is suggested that differences in the hearing threshold (at high frequencies) in analyzed groups may be due to differences in spectral composition of noise and show the need to continue the undertaken studies.

Theoretical Predictions and Actual Hearing Threshold Levels in Workers Exposed to Ultrasonic Noise of Impulsive Character— A Pilot Study

A comparison of predicted and measured HTLs suggests that the ISO 1999:1990 method, intended for audible noise, might also make it possible to predict reliably permanent hearing loss after exposure to ultrasonic noise.

Does airborne ultrasound lead to activation of the auditory cortex?

Although test subjects reported audible sounds above the threshold, no brain activity was identified in the above-threshold case under current experimental conditions except at the highest sensation level, which was presented at the lowest test frequency.

Large band spectral analysis and harmful risks of dental turbines

The spectra of the sounds generated by high-speed air turbines, ranging from audible to ultrasonic frequencies (0–70 kHz), show the presence of four main peaks, which reach levels which may provoke short- or long-term negative physiological disturbances and hearing-damage risk.

Development of a high-frequency and ultrasound personal noise ex- posure meter for identification of sufficient sound rating quantities

Many workplaces are exposed to high-frequency audible noise and/or ultrasonic noise with dominant contributions from frequencies between 10 and 40 kHz. Apart from hearing loss, that may occur at high

Effects of Ultrasonic Noise on the Human Body—A Bibliographic Review

This review describes hearing and nonhearing effects (thermal effects, subjective symptoms and functional changes) of the exposure to noise emitted by ultrasound devices.
