BOSE ANC主动降噪系统详细讲解介绍


  现在越来越多的车型都搭载主动降噪功能,尤其是在一些美系车跟日系车中20多w就开始搭载该系统,有了这个系统噪音会降低吗?这个系统的工作原理是怎样的?
  带有主动降噪功能的车就来自bose开发的anc主动降噪系统。BOSE是主动降噪技术的先驱者,原理在于首先要收集噪音的波型特点,然后通过内置的处理芯片运算出反相的波,再通过高还原度扬声器相抵消。所以主动降噪系统必备的设备有拾音器、处理芯片、扬声器,每一个部分都要保证高质量才能达到最终的效果,故成本上就要比传统非降噪设备高。
  另外BOSE ANC主动降噪系统推出的目的在于让汽车行业减少对物理降噪的依赖,毕竟大量的隔音材料对车身自重的增加是不可避免的,从而影响动力和油耗。

More and more models are now equipped with active noise reduction, especially in some American cars and Japanese cars. More than 20 w have begun to carry the system. With this system, noise will be reduced? How does this system work?
The car with active noise reduction comes from the anc active noise reduction system developed by Bose. BOSE is the pioneer of active noise reduction technology. The principle is to first collect the noise wave characteristics, and then use the built-in processing chip to calculate the inverted wave, which is then cancelled by the high-reduced speaker. Therefore, the necessary equipment for the active noise reduction system is a pickup, a processing chip, and a speaker. Each part must ensure high quality to achieve the final result, so the cost is higher than the conventional non-noise reduction equipment.
In addition, the purpose of BOSE ANC active noise reduction system is to let the automotive industry reduce its dependence on physical noise reduction. After all, a large number of sound insulation materials on the increase in body weight is inevitable, thus affecting power and fuel consumption.
