Noise-induced hearing loss is a big issue for motorcyclists. The interior of a helmet can be an audibly offensive place: engine noise, road noise, and the sound of rushing wind combine to create a din that routinely exceeds 80 decibels, a level that experts consider “very loud” and potentially damaging. Your ears are a delicate system made up of tiny bones, fragile nerves, and microscopic hair cells, and the vibration caused by all those dB’s can be disastrous. When any of these components are damaged, the transmission of sound is permanently altered. The noise level isn’t the only issue; duration is a major factor as well. And as motorcyclists, we typically like to ride for as long as possible, making us even more susceptible to hearing loss.
