&PESQ can be used to evaluate the background or environmental noise (such as car, street, etc.) in speech. Noise recording should be done through an appropriate filter similar to the modified transmission characteristics, which is particularly important for low frequency signals, such as car noise severely attenuated by mobile phone filter, and then horizontally aligned to the required level for testing. For the subjective interference of PESQ in ACR context, due to the noise and any coding distortion, the original signal using PESQ should be clean, but the noise should be added when the signal is transferred to the system under test. PESQ verifies the noise input signal.  ;
