Usually when appreciating the sound quality of a set of speakers, the most important thing is the hardware elements such as electronic devices, speakers, wires, etc., in fact, there are many other elements that are not easy to be found by us, such as: the sound reproduction of the speaker, the external sensation, the resonance of the listening environment, and the acoustic characteristics of the listening room. Horn sounds.

When the speaker is broadcast, the sound wave announced by the loudspeaker will cause a sensation on the wall, roof and ground, and even some will directly or directly impact the speaker device, and these sensations will be transmitted through different channels; For example, the speaker rack, air, etc., at different speeds and intensities successively fed back to the device, causing a sensation and its own resonance, resulting in the operation of the sound system in the electronic circuit of the wonderful electronic flow changes and the sound changes, making the sound slightly ambiguous and forming a subtle distortion.

The resonance characteristics of the environment: the object has its inherent resonant frequency according to the different raw materials, shapes, and sizes, and when the external oscillation energy is added to the object, if the frequency is equal to or close to its resonant frequency, the object will oscillate violently synchronously and violently into resonance. Is there any way to eliminate or reduce the intrinsic resonance of the listening room, so that its frequency response is flattened and the loudspeaker system is excellent?

This is the physical property of the object that cannot be eliminated, only weakened. For example, a rectangular room is easier to deal with resonances, while a square room is particularly difficult to deal with standing waves. Sensational elements in the outside world: If the listening room is near the roadside, factory, construction site, elevator room, pump room, etc., it is very simple to be disturbed by noise or ultra-low frequency, and the speaker device is caused by the sensation and the sound is ambiguous.
