Noise in the outpatient operating room

Area of Science:

• Healthcare acoustics
• Hospital environmental quality
• Patient safety

Background:

• Hospital noise negatively affects patient anxiety and doctor concentration.
• Outpatient operating rooms are increasingly common for minor surgeries.
• Understanding and mitigating noise in these settings is crucial.

Purpose of the Study:

• To investigate noise exposure levels in outpatient operating rooms.
• To identify sources of noise in these environments.
• To evaluate the effectiveness of noise control strategies.

Main Methods:

• Noise levels were monitored in three hospitals.
• Average noise exposure intensity during outpatient procedures was analyzed.
• Noise control measures were implemented in an experimental operating room (EOR) for evaluation.

Main Results:

• Outpatient operating room noise (68.3±14.7 dB) was significantly higher than inpatient operating room noise (45.7±9.6 dB).
• Implemented noise control reduced EOR noise (59.2±13.4 dB), but it remained higher than inpatient settings.
• Primary noise sources included external vehicles, medical equipment, ambulances, crowds, and communication devices.

Conclusions:

• Noise exposure is a significant issue in outpatient operating rooms.
• Noise control measures can effectively reduce noise levels.
• Further strategies are needed to achieve optimal noise reduction in these settings.
