Ambulance Crew Noise Exposure Levels with Siren and Traffic Analysis

A study dataset measuring sound pressure levels inside ambulances during emergency trips and full driver shifts. The data was collected and statistically analyzed by Rafaella Cristina Oliveira to assess compliance with Brazilian regulatory standards. Results indicate average noise levels exceeding 85 dB(A) and noise doses ranging from 17.51% to 155.68% of the recommended limit.

Use Cases

• Modeling the association between siren use and noise levels based on the statistical analysis mentioned.
• Assessing compliance with workplace noise regulations based on measured sound pressure levels.
• Analyzing the influence of traffic conditions on occupational noise exposure during emergency trips.

Strengths

• Includes specific statistical results, such as average equivalent continuous sound levels exceeding 85 dB(A).
• Reports a concrete range for noise dose percentages, from 17.51% to 155.68%.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the study's Brazilian context.
