Summary
Aviation engineers experience excessive noise exposure, impacting their hearing, especially during work and sleep. Living closer to airfields significantly worsens auditory thresholds, highlighting aviation noise as a critical ecological factor.
Area of Science:
- Environmental Health
- Occupational Health
- Acoustics
Background:
- Aviation engineers and residents near airfields are exposed to high levels of diurnal noise.
- This noise exposure may exceed normal values, particularly during work and sleep periods.
Purpose of the Study:
- To analyze average diurnal noise doses in aviation personnel and nearby residents.
- To investigate the relationship between proximity to airfields and auditory health.
- To assess the impact of aviation noise on hearing fatigue and restoration.
Main Methods:
- Analysis of average diurnal noise doses.
- Comparison of auditory thresholds between residents at different distances from airfields (1-2 km vs. 5-6 km).
- Experimental validation using audiometry and impedometry.
Main Results:
- Noise doses for aviation engineers often exceed normal levels, affecting work and sleep.
- Individuals living 1-2 km from airfields exhibited significantly higher auditory thresholds (1,000-8,000 Hz) compared to those living 5-6 km away.
- Excessive non-occupational noise impairs hearing recovery and promotes fatigue.
Conclusions:
- Aviation noise is a significant ecological factor affecting auditory health.
- Proximity to airfields is directly correlated with hearing impairment in exposed populations.
- Interventions are needed to mitigate the adverse effects of aviation noise on hearing.
