"Experienced motorcyclists know the importance of wearing good hearing protection while out on a trip. At a speed of 100 kilometres (60 miles) per hour, the wind noise under the helmet can quickly get as high as 94 decibels. This is harmful after just fifteen minutes. The same more or less applies to open-top cars. At a speed between 80 and 112 kilometres (50 to 65 miles) per hour, the sound caused by the wind created by driving can reach as much as 110 decibels, approximately the same as the noise level of a drill. If you expose your hearing to this for longer than seven minutes, you will definitely incur damage to your hearing", according to Lisette de Roode, Managing Director at Alpine Hearing Protection
