轮胎噪声是由轮胎与路面摩擦所引起的。不同类型路面对胎噪的影响是不同的。降低轮胎噪声有很多种方式。日本住友橡胶工业株式会社开发出了把泡沫层粘贴在轮胎胎面下方的气密层的方法,并将这种降低轮胎噪声的方法(轮胎消音器)应用在了任何一种商业化轮胎上。 Tire noise is caused by tire friction with the road. The impact of different types of road on tire noise is different. There are many ways to reduce tire noise. Sumitomo Rubber Industries, Ltd. of Japan has developed a method of attaching a foam layer to the inner liner below the tire tread and applied this method of reducing tire noise (tire silencer) to any commercial tire.
