Abstract
The National Institute for Occupational Safety and health (NIOSH) received a request to conduct a health hazard evaluation at an air traffic approach control tower. There was concern that air traffic control (ATC) specialists may be exposed to noise greater than 85 decibels on an A-weighted scale [dB(A) over an 8-hour time-weighted average period from their communication headsets as a result of brief, loud tones transmitted intermittently through the headset receivers. A compression unit that would limit the intensity of these tones had been designed by an outside firm and had been installed at the radar screen positions prior to the NIOSH site visit. The survey was designed to determine if the compression units were effective in reducing sounds that reached the controllers' earpieces and if any permanent hearing damage had occurred in the population of ATC specialists.
