Wind-Related Noise Experienced by Cyclists Can Contribute to Noise-Induced Hearing Loss

September 21, 2016

FOR IMMEDIATE RELEASE

DETROIT – A new study led by otolaryngologists Michael Seidman, M.D., director of Otologic/Neurotologic/Skull Base Surgery at Florida Hospital Celebration Health and Anna Wertz, M.D. from the Henry Ford Hospital Department of Otolaryngology – Head and Neck Surgery found that the wind-related noise experienced by cyclists can reach levels loud enough to contribute to noise-induced hearing loss.

Using the Ford Motor Company aero-acoustic wind tunnel, researchers generated wind speeds ranging from 15-60 mph and used microphones attached to a cyclist’s ears to measure the noise level at various speeds. Sound measurements were taken with the head positioned at 15 degree increments relative to the wind from 0 degrees to 180 degrees.

Wind noise ranged from 85 decibels at 15 mph and increased proportionally with speed to a maximum of 120 decibels at 60 mph.

“These findings are important because noise-induced hearing loss can begin with sounds at or above 85 decibels,” said Anna Wertz, M.D., Henry Ford otolaryngologist and co-author of the study. “Short-term exposure to loud sounds isn’t likely to have a lasting effect on hearing, but prolonged or repeated exposure can lead to permanent damage."

The study also found that the noise level was greater in the downwind ear, which was facing away from the wind. The researchers say this finding may be due to air turbulence caused from eddy currents observed on the downwind side.
