When the roads are noisy

Often, car owners complain about the noise made by tires. This is especially true for electric vehicle owners, as with the disappearance of the internal combustion engine, the tires remain the noisiest element. This is indeed the case, but it's essential to understand that noise causes acoustic discomfort, but does not pose a danger. The noisier the tires, the more likely they are to be effective on wet and snowy roads.
However, it's not just the tires that make noise while driving. The road surface also accounts for a significant portion of the noise. Specifically, the type of asphalt, or rather, its grain size.

Different types of road surfaces produce varying levels of noise. For example, asphalt roads are usually quieter than cobblestone or concrete paths.
A surface with large grain size or unevenness, such as potholes and cracks, can lead to increased noise, as the vehicle's tires pass over them and create vibrations and sound.

It's also worth noting that traffic noise is amplified at higher speeds, so the road surface can also affect the speed of traffic and, consequently, the level of noise. The higher the speed, the higher the noise.

Many countries and regions pay attention to reducing traffic noise, and as part of infrastructure projects, special technologies and materials may be implemented to reduce noise on roads. This can include the use of quieter asphalt mixtures, sound-absorbing barriers, and other measures to reduce the negative impact of noise on the environment and residents.
