视频信噪比 “噪声”的简单定义就是：“在处理过程中设备自行产生的信号”，这些信号与输入信号无关。对于多媒体硬盘播放器来说，信噪比都是一个比较重要的参数，它指音源产生最大不失真声音信号强度与同时发出噪音强度之间的比率称为信号噪声比，简称信噪比（Signal/Noise），通常以S/N表示，单位为分贝（dB）。对于多媒体硬盘播放器来说，该值当然越大越好。 目前多媒体硬盘播放器的信噪比有56dB、60dB、65dB、85dB、90dB、95dB等等，我们在选择多媒体硬盘播放器的时候，一般都选择60dB左右的，但即使这一参数达到了要求，也不一定表示机子好，毕竟它只是多媒体硬盘播放器性能参数中要考虑的参数之一。
