Some individuals must wear hearing protectors in order to reduce their noise exposure even after all other avenues of exposure control have been exhausted. However, is it reasonable to expect these individuals to wear earmuffs for long, continuous periods? Measurements of 39 commonly available earmuffs show that in all cases, the pressures experienced on the side of the head are sufficient to restrict blood flow and hence over time produce discomfort. For better results and compliance with earmuff use, breakout times may be necessary to alleviate feelings of discomfort.
