The biggest risk to your hearing when riding a motorcycle is exhaust and engine noise, right?
Wrong. It’s actually the wind noise.
Thirty million Americans are at risk for noise-induced hearing loss (NIHL) in the workplace, in recreational settings and at home—and motorcyclists are among them1. The good news is that NIHL is 100 percent preventable, but once it happens, the hearing loss can be permanent. Among motorcyclists, NIHL is attributed to noise from the turbulent airflow around the helmet, “wind noise.”
Many different styles of motorcycle helmets are available, with full-face and open-face helmets being the two main options. However, noise levels under a motorcyclist’s helmet are high – between 80 to 110 dB2 – and increase rapidly with road speed, which can cause hearing loss after just an hour. Unfortunately, many motorcyclists are under the impression that a helmet provides adequate hearing protection.
Over the past several years, motorcycle development has led to quieter bikes with radically improved performance. However, excessive exposure to noise caused by wind is still a concern. At 40 mph, a motorcyclist is exposed to 90 dB of low frequency wind noise caused by turbulent airflow around the helmet. At 100 mph, the noise level is around 110 dB, which is safe for less than five minutes per day.3 The faster you go, the louder the sound is. The longer you are exposed to it, the more it can damage or destroy the inner ear’s sensory hair cells, which cannot grow back on their own.
Regardless of the choice of helmet, motorcycle or seating position, noise levels are consistently damaging and are in excess of 90 dB. Helmets offer protection from fatal injuries, bumps and bruises, but do not keep out much of the noise. Studies have indicated that the maximum noise reduction from wearing a typical helmet is around 7 to 10 dB4. After long periods of time at high speeds, riders commonly report symptoms like fatigue, tinnitus, headaches and even disequilibrium.3
There is no cure for permanent hearing loss. One of the most obvious “treatments” for NIHL is avoiding exposure to loud noise. Hearing loss is rarely painful and the symptoms are usually vague feelings of pressure or fullness in the ears and may go away minutes, hours or days after the exposure to noise ends. Many people assume that if the symptoms go away, their ears have “bounced back” to normal and don’t realize that hearing loss accumulates over a lifetime.
