Summary
Electronic arcade games generate significant noise, reaching up to 90 dB(A), potentially causing temporary hearing loss. Game centers should implement noise controls and employee education for hearing conservation.
Area of Science:
- Audiology
- Environmental Health
- Acoustics
Background:
- Electronic arcade games are a source of significant noise pollution.
- Understanding noise exposure levels is crucial for public health and occupational safety.
Purpose of the Study:
- To measure and analyze noise levels in electronic arcade game centers.
- To assess the potential risk of noise-induced hearing loss for patrons and employees.
Main Methods:
- Noise measurements were conducted in three game centers, collecting 192 samples per location.
- Sound pressure levels were analyzed using 1/3 octave bands.
- Noise pollution levels (LNP) and L90 were computed.
Main Results:
- Background noise averaged 61-64 dB(A), while game noise reached 88-90 dB(A).
- Intense noise levels were concentrated between 0.5-2.0 kHz.
- Noise pollution levels (LNP) ranged from 93.3-96.6 dB(A), and L90 from 85.1-87.3 dB(A).
- Estimated temporary threshold shift (TTS) of 4-8 dB at 4.0 kHz after less than one hour of exposure.
- 8-hr equivalent continuous sound levels (Leq,8) for employees ranged from 80.3-87.5 dB(A).
Conclusions:
- Arcade game noise levels pose a risk for temporary threshold shift.
- Recommendations include limiting maximum noise levels, educating employees on hearing risks, and establishing hearing conservation standards.
