In the sound reinforcement system, the polarity of microphone signal output line or speaker power signal input line is reversed, and the system has phase distortion and other reasons, which will cause a variety of sound phase inversion problems and phase shift problems. Whether the phase relationship of sound is correct or not (especially the opposite phase) will directly affect the quality of sound reproduction, which has been confirmed by modern audio technology and is an undoubted fact.
However, at present, the sound industry does not seem to attach great importance to the problem of system phase reversal and phase shift, and many people do not even know that there are various phase problems in the sound system.
After connecting the system, most sound workers do not consider the phase of microphone and speaker at all; When the equipment and system are adjusted, a series of possible problems caused by the adjustment are not considered, which is undoubtedly a pity for modern audio systems.
The phase problem is a common problem that can not be ignored in the sound system. The sound industry should attach great importance to it and whether it will increase the chance to miss the high fidelity sound quality. The text will specifically discuss various phase problems existing in the sound system, analyze various aspects of the impact of phase shift on the reproduction of sound and the specific methods to check and solve the phase reversal. I hope that through this article, we can have a full and comprehensive understanding of the phase problem of the sound system.
The inversion of audio system includes two aspects: one is the case that the phase difference of two same audio signals is 180 degrees; The other is that for microphones and speakers, the vibration direction between the diaphragm of each speaker, between microphones or between speakers and microphone diaphragm is opposite under the same sound. The concept of phase may not be well understood in words, but through the examples of phase reversal in practical applications, we can clearly understand what it is and what impact it will have on the sound. To sum up, there are five types of inversion in the sound reinforcement system, namely, inversion between left and right channel speakers, inversion between real phases, inversion between microphones, inversion of some speakers in the array composed of multiple speakers, and inversion of different speakers in one speaker.
Phase shift or phase distortion is a situation where the phase difference between two sound waves is not equal to 180 degrees. Any sound system may have phase shift or phase distortion, which is just a phase shift and phase distortion phenomenon, but the degree of phase shift and phase distortion is different. It has a certain relationship with the phase frequency characteristics of the sound equipment itself and the sound system adjustment.
