Home theater sound what kind of distortion is harmful

Often listen to music people may know, using different equipment, enjoy the same music, you can hear the sound of several different tastes, because each kind of equipment is not the same degree of distortion, and the results may make music more pleasant, also may be bad. But there are some distortion is harmful, we look at the concentration of typical distortion.

Boom: unless for testing, there should not be any higher case, sonic boom appeared for many reasons, generally more than in the source, may also be CD disc scratch or audio files seriously damaged, when the signal is suddenly opened or the introduction of other strong interference, will produce a sonic boom. The transient performance of relatively poor equipment, may produce a sonic boom in signal mutation moment.

Top: but when the signal is too large, the signal will overflow, overflow part of the results of the spill was cut off, like a knife cut, the distortion is the most uncomfortable. Many friends like to use the equalizer to adjust the sound, but an increase in the strength of the gain, it is prone to distortion.

Fricative circle: large amplitude motion of loudspeaker system, weak control may make the loudspeaker coil edge, serious distortion may damage the speaker, "Chi Chi".

If the case is too thin, or the plate is too thin, the case of high power output, the box may be shaking violently, resulting in buzzing.

Leakage: speaker in the movement, the box body can compress the air pressure inside and outside the box body anisobaric, will cause rapid air suction or spit out, if the assembly process problem (e.g. not installed seal), the air will be through the slit, the high frequency will cause bad distortion. Why a lot of active bookshelf box is not willing to install the volume control knob on the front panel, mainly because the assembly is slightly careless, leading to leakage.

Band collapse: We tested a lot of speakers there are serious frequency collapse, for example between the satellites and low sound connection completely interrupted, and even some bookshelf box factory there if the total collapse of the problem. The collapse of the frequency band, like the lack of color monitor, is a harmful distortion.
