Noise exposure in the operating room

This paper discusses a study done to determine noise levels in operating rooms

High frequency audiometry: sound suite versus hospital room

This paper discusses a study to assess and compare frequency audiometric thresholds obtained under two listening environments--a sound suite and a typical hospital room.

Evaluation of noise levels experienced by medically fragile neonates during emergency helicopter transport

There was a concern medically fragile infants may be exposed to high noise levels during emergency helicopter transport. This study had been initiated in 2007. Data was collected using a Larson Davis noise dosimeter. The purpose of this study was to collect additional data to evaluate the noise exposure experienced by medically fragile neonates during emergency transport via helicopter inbound/outbound of St. Louis Children’s Hospital, St. Louis, MO. The results suggested neonates may be exposed to noise levels ranging 85 to 95 dBA during transport. These high noise exposures may pose a risk to hearing.
