The Journal of the Acoustical Society of America has published a study titled “Aeroacoustic Sources of Motorcycle Helmet Noise” in which the various frequencies and decibel levels of helmet-generated noise were measured and tested, I became very interested in the study’s findings. Conducted by the University of Bath and Bath Spa University in England, the researchers performed a very intuitive test where they placed a mannequin’s head in a wind tunnel, turned on the wind, and recorded the sound volume and frequency at various points in and around the helmet. The conclusion was that at even normal legal riding speeds, deafening levels of sound were reaching the eardrum, primarily due to the chin bar on the helmet.
