Choice Of Autoacoustics
Sabvuffer Corps
In order to reproduce low sabove frequencies, acoustic treatment is required. Let's see what this is and what it takes. We'll take the simplest dynamic flux. When the diffusor moves forward, it creates air compression for a moment. The air will then escalate sharply and repress the air, but already at some distance from the previous one. These compressions and air discharges are sound waves we hear.
Now, we'll go back to our occasion when the dynamics made a hesitation and squeezed some air. At this very moment on his rear face, there is a completely untouched phenomenon of air discharge. Low-frequency waves are well affected by obstacles, as a result of the interaction between the rear and the frontal wave, we will receive a sharp decrease in sound pressure. It's called acoustic short circuit.
If this doesn't happen, we'll have to separate the waves of the front from the waves of the rear. This can be done either by means of a big screen or by placing our dynamics in a body. That's the screen or the hull, and it's acoustic.
In fact, there are many different acoustic applications, but the main features include an endless screen (free-air), a closed box, a phaser. Now elaborate on each of them.
Endless screen or free-air
In this form of discharge, it is understood that the waves of the front and rear of the dynamic will be divided by an endless big screen. In practice, such a screen means a sufficiently large hull where the inmate ' s air is much less than the diffuser ' s suspension. The main advantage of this discharge is the simplicity of the installation and the nature of the bass. But the Peace of the Unions would like to point out that it will have to be paid for by a variety of combinations, changing the free volume of the trunk and not a very high level of sound pressure.
