The invention provides a novel tire noise reduction sponge processing method. The novel tire noise reduction sponge processing method is characterized by specifically comprising the following steps of S1, metering and mixing, S2, discharging and forming, S3, curing treatment, S4, oxyhydrogen explosion treatment, S5, cutting and S6, packaging and recycling. According to the invention, an air bubble film on the surface of the sponge is removed through hydrogen-oxygen explosion, and sound absorption and noise reduction are carried out by using a microporous structure of the sponge, so that noise generated in the running process of the wheel tire is insulated, the driving experience of a driver and the riding experience of a passenger are improved, and the effect of increasing the practical performance is achieved. 本发明提供了一种新型轮胎降噪海绵加工方法，其特征在于：具体包括以下步骤：S1：计量混合、S2：出料成型、S3：熟化处理、S4：氢氧爆炸处理、S5：裁切、S6：打包回收。本发明通过氢氧爆炸去除海绵表面的气泡膜，利用海绵自身的微孔结构进行吸音降噪，从而对车轮轮胎行驶过程中所产生的噪声进行隔音，提高了驾驶人员的驾驶体验和乘车人员的乘车体验，起到了增加实用性能的作用。
