Brief Summary

This prospective observational study aims to evaluate the effects of environmental noise in the intensive care unit on healthcare workers. Healthcare personnel working in intensive care units and hospital wards will be compared in terms of cochlear function, noise sensitivity, anxiety levels, perceived noise burden, and functional effects of noise exposure. The study seeks to determine whether long-term occupational exposure to intensive care unit noise is associated with measurable auditory and non-auditory effects in healthcare workers.

Conditions

Noise Exposure; Occupation; Intensive Care (ICU); Healthcare

Keywords

noise; noise exposure; intensive care unit; anxiety

Outcome Measures

Primary Outcomes (1)

• Cochlear Function Assessed by DPOAE

  Cochlear function will be evaluated using distortion product otoacoustic emission (DPOAE) amplitudes and signal-to-noise ratio values, and compared between healthcare workers in the ICU group and the ward group.

  At baseline
