According to research results from international authoritative organizations, car users are paying more and more attention to tire noise year by year. In the current perception of mainstream consumer groups, it is difficult for tires with poor silent performance to be associated with the word "high-end", especially among Asian car owners. group. To this end, tire companies are also making every effort to develop quieter products to demonstrate their technical strength.
The most popular silent tire technology at present is "silent cotton technology". Why can drivers and passengers feel quiet and relaxed after tires are covered with professional silent cotton?
First of all, the frequency range of the noise emitted by tires is very wide, from the bass range to the mid-to-high range. There are two ways in which these noises are transmitted from the tires into the car: one is transmitted through the air, and the other is transmitted through the metal structure of the car body. The noise transmitted through the air is usually mainly high-pitched signals, which can be easily absorbed and blocked by sound insulation materials.
The main thing that is transmitted through the metal structure of the car body is bass noise, which is almost impossible to solve through vehicle sound insulation. Moreover, noise in the bass noise frequency range of about 150~250Hz is an important cause of irritability and irritability in drivers and passengers. Therefore, we hope to greatly improve the low-frequency noise situation in the car, thereby greatly improving driving comfort.
Currently, the most effective method for dealing with low-frequency noise is tire silent cotton. For example, Tir-ace Carrera Pro tires used are affixed with specially optimized and designed silent cotton. It can effectively absorb noise in the 150~250Hz range, thereby achieving the purpose of quietness and comfort.
