Sick building syndrome: the acoustic environment.

Author(s) : BURT T.

Summary

Describes an investigation of the acoustic environment in an office building with a history of occupant complaints. A scoring system was developed for rating occupants' sick building symptoms. High scores were associated with high levels of infrasound (greater than 20 hertz) in the rooms and low scores with low levels. The infrasound came from the ventilation system as airborne noise rather than as structure-borne vibration. Levels of infrasound were often amplified in the tightly-sealed rooms, and could be even higher at workstations than at supply grilles. Concludes that repeated or long-term exposure to infrasound may be triggering an allergic-type response.
