With the significant improvement of people's material living conditions in recent years, more and more car owners have higher requirements for their cars. As is well known, the huge noise generated when cars are driving at high speeds can affect the driver's mood. If this continues for a long time, the situation can be serious and even cause nerve exhaustion. So in order to create a better driving environment, many car owners now do car sound insulation. With the continuous improvement of urban economic level, the profession of car sound insulation has developed rapidly. Of course, depending on the actual situation of the vehicle and the influence of various factors, the sound insulation effect of sedans also varies. Below, LED Bluetooth speakers will explain to us which factors determine the primary quality of car sound insulation.

1. Car doors

The thickness and structure of car doors can affect the sound insulation effect of the entire interior of the car, because the four doors of the car, as the large moving parts on the car, have a significant impact on the sound insulation effect of the entire car. Often, the noise of lightly floating doors when closed is relatively higher, so it is necessary to do sound insulation for such doors.

2. Chassis

When the car is driving at high speed, the chassis noise is very significant. The sound insulation effect of this area mainly depends on the manufacturer's chassis manufacturing strength and the cost invested.

3. Tires

Tire noise is also an important source of car noise. In addition to the quality and softness of the suspension, tire noise also depends on the brand and production process of the tires. Often, tires with good noise reduction performance do not have good wear resistance, while tires with wear resistance do not have ideal noise reduction performance.
