The design goal for audio equipment is that all distortion be so low in level it can't be heard.
声频设备附近的墙壁会反射声波，空气中的声波叠加，产生频率响应误差(亦称梳状滤波器)。
Nearby room boundaries can create frequency response errors (called comb filtering) due to wave reflections combining in the air.
该设备还能收听跨越17个八度音阶的声频，其音调范围远高于蚊子的蜂鸣，而远低于低沉的雾角。
It can also hear sound frequencies across a span of 17 octaves, spanning pitches far higher than the whine of a mosquito and far lower than a rumbling foghorn.
声频材料经过一件设备处理后，失真添加了悦耳或刺耳的新频率。
When music passes through a device that adds distortion, new frequencies are created that may or may not be pleasing to the ear.
