Sound Quality Head and Torso Simulators Types 4100 and 4100 D are manikins designed for sound quality testing. The recorded signals from Types 4100 and 4100-D can be modified using a wide range of time/frequency domain editing techniques using a sound quality software program and a PC. The modified signals can then be compared with the original in a listening test. If the modified signal is preferred, information on the changes in the noise can be used by the product designer to obtain – by physical changes – improved sound quality. 
声音质量的头和躯干模拟器的类型4100和4100 D是专为语音质量的测试假人。用一个声音质量的软件程序和电脑，采用频率域的编辑技术可以修改所记录的信号。在听力测试中，修改后的信号与原始信号相比较。如果修改后的信号质量更优，那么产品设计师可以将相关信息用于噪声，用物理变化，改善声音质量。
