随身听中的噪音一般有两种,一种称为本底噪音,表现为“沙沙”声,由随身听本身的磁头放大器产生,这种噪音是很难消除的,只能靠选用优质的元件及优良的线路设计来降低。实践证明,磁头放大器的本底噪音对音乐欣赏影响很小,虽然人们能明显地感到其存在,但人脑对其并无明显的排斥性。而另一种噪声则会使人感到厌烦,那就是马达干扰噪音,其主要表现为“嗡嗡”声,特别在电池剩余容量不 Walkman in the noise there are two general, one is called the background noise, the performance of “rustle” sound generated by the Walkman head amplifier, this noise is very difficult to eliminate, can only rely on the selection of high-quality components And excellent circuit design to reduce. Practice has proved that the noise floor of the head amplifier has little effect on music appreciation, although people can clearly feel its existence, but the human brain has no obvious exclusion. While the other kind of noise can be annoying, it is that the motor interferes with the noise, which is mainly manifested as “buzzing” sound, especially when the remaining capacity of the battery is not
