Detailed the lexia 3 ins and outs of tire noise

Formation is mainly determined by the lexia 3 tire and the road noise of the tire when traveling. The roughness of the pavement, the pavement structure and pavement material factors affect noise size. In addition, the width of the tire and rim and also restricting the noise reduction more difficult, wide tires due to the wide bearing surface noise's sake will become larger than those narrower tire size, wide tire will displace more air and promote more "air mass" to vibrate.

    For a front engine car, the passengers sitting in the back would be easier aware of tire rolling noise, because the rear of the vehicle by the engine and wind noise impact is relatively small, the tire noise is prominent So when we judge the tire noise, most of them choose to sit in the back to be screened.

    The human ear lexia3 V47 PP2000 perceives to rolling noise is emitted by the sound source through the medium of air constantly vibration into our ears. Speaking of the above, due to certain characteristics, and factors change, tire noise is also big, sometimes small, which basically can be summed up as a combination of road and tire.

    Pavement structure and materials for tire noise has a significant impact on, for example, when the vehicle through the wet pavement noise decibel level is significantly higher than the vehicle level through dry pavement.

    Tire tread design for tire noise plays a dominant role, for example, a tire tread groove to 90 degrees, the same pattern of a car assembly the slope into obvious acute angle design We can easily compare the 90 degree groove pattern, the tire tire noise worse.

    Wedge Auctions ribs of the tire when driving is not stable enough, will pass through the air due to its larger amplitude deformation during rotation will, in promoting and squeeze air will produce air to vibrate, when vibration strong The media arrived in our ears.

    Wide tires noisy is not difficult to understand the friction surface increases, the noise also increases. Same pattern design, many high-performance tires usually larger drainage pattern of the word "person", we are most familiar with the series is the best flying boots, the type of tire tread groove will continue to squeeze pressure, squeeze out the air, the resulting vibration will certainly be greater than the ordinary pattern design, body sealing noise immunity bad will directly affect the vehicle's ride comfort and tire noise.

    This we can summarize tire noise, tire size large olfactory directly decided tire noise level, then, the design of the tire tread is what we can not be ignored as a major factor promoting the air to produce the grooves between the tread will squeeze vibration, the pumping effect of the air also cause pattern distortion, may be compressed, may be inflated.
