When riding a motorcycle with earplugs in and a helmet on, the level of sound you can hear will be significantly reduced compared to riding without earplugs. Earplugs are commonly used by motorcyclists to reduce the impact of wind noise, which can be quite loud and potentially damaging to hearing over extended periods.
Earplugs work by attenuating or dampening sound, meaning they reduce the overall volume of sounds that reach your ears. They are designed to filter out harmful or excessive noise while still allowing you to hear essential sounds such as traffic, sirens, and horns.
There are different types of earplugs available, ranging from foam to custom-molded options, each with different levels of noise reduction.
With proper-fitting and appropriate earplugs, you should still be able to hear important sounds while riding, such as engine noise, sirens, or honking. However, the overall volume will be reduced, and some quieter sounds or conversations may be more difficult to hear or understand. It's always recommended to prioritize safety and be vigilant on the road, regardless of the use of earplugs or helmets.
