Noise exposure and hearing status among employees using communication headsets.

Objectives: The objective of this study was to assess the hearing of employees using communication headsets with regard to their exposure to noise.

Material And Methods: The study group comprised 213 employees, including 21 workers of the furniture industry, 15 court transcribers and 177 call center operators, aged 19-55 years, working with headsets for a period of up to 25 years. All the participants underwent a standard puretone audiometry, extended high-frequency audiometry (EHFA) as well as transient-evoked otoacoustic emissions (TEOAEs) and distortion-product otoacoustic emissions (DPOAEs).

Hearing status of people occupationally exposed to ultrasonic noise.

Objectives: The aim of the study was to evaluate the hearing status of operators of low-frequency ultrasonic devices compared to employees exposed to audible noise at a similar A-weighted sound pressure level (SPL) but without ultrasonic components.

Material And Methods: Standard pure-tone audiometry, extended high-frequency audiometry (EHFA), transient-evoked otoacoustic emissions (TEOAE), and distortion-product otoacoustic emissions (DPOAE), as well as questionnaire surveys were conducted among 148 subjects, aged 43.1±10.

Pure-Tone Hearing Thresholds and Otoacoustic Emissions in Students of Music Academies.

The objective of this study was to assess the hearing of music students in relation to their exposure to excessive sounds. A standard pure-tone audiometry, transient-evoked otoacoustic emissions (TEOAEs) and distortion-product otoacoustic emissions (DPOAEs) were determined in 163 students of music academies, aged 22.8 ± 2.

[Evaluation of noise exposure and risk of hearing impairment in employees using communication headsets or headphones].

Background: The aim of the study was to assess the noise exposure and risk of noise-induced hearing loss (NIHL) among users of communication headsets (CHs) or headphones.

Material And Methods: Noise measurements and questionnaire surveys were carried out in 74 workers (aged: 31.8±7.

Noise exposure and hearing status among call center operators.

Introduction: The overall objective of the study was to assess noise exposure and audiometric hearing threshold levels (HTLs) in call center operators.

Materials And Methods: Standard pure-tone audiometry and extended high-frequency audiometry were performed in 78 participants, aged 19 to 44 years (mean ± standard deviation: 28.1 ± 6.

Response to Noise Emitted by Wind Farms in People Living in Nearby Areas.

The aim of this study was to evaluate the perception and annoyance of noise from wind turbines in populated areas of Poland. A questionnaire inquiry was carried out among 517 subjects, aged 18⁻88, living within 204⁻1726 m from the nearest wind turbine. For areas where respondents lived, A-weighted sound pressure levels (SPLs) were calculated as the sum of the contributions from the wind power plants in the specific area.

Exposure to excessive sounds and hearing status in academic classical music students.

Objectives: The aim of this study was to assess hearing of music students in relation to their exposure to excessive sounds.

Material And Methods: Standard pure-tone audiometry (PTA) was performed in 168 music students, aged 22.5±2.

Exposure to excessive sounds during orchestra rehearsals and temporary hearing changes in hearing among musicians.

Background: It has been shown that musicians are at risk of noise-induced hearing loss. The aim of the study has been to evaluate the temporary changes of hearing in the case of orchestral musicians after group rehearsals.

Material And Methods: The study group comprised 18 orchestral musicians, aged 30-58 years old (mean: 40 years old) having 12-40 years (mean: 22 years) of professional experience.

Evaluation of annoyance from the wind turbine noise: a pilot study.

Objectives: The overall aim of this study was to evaluate the perception of and annoyance due to the noise from wind turbines in populated areas of Poland.

Material And Methods: The study group comprised 156 subjects. All subjects were asked to fill in a questionnaire developed to enable evaluation of their living conditions, including prevalence of annoyance due to the noise from wind turbines and the self-assessment of physical health and well-being.
