Acoustic tubes
Acoustic tube low tube usually refers to a section of pipe in a lower position in the acoustic tube. In some cases, in order to improve the efficiency and accuracy of acoustic wave transmission, it is necessary to drill holes in the low tube section of the acoustic tube. The purpose of punching is usually the following:

Drainage: If water accumulates inside the acoustic tube, it will affect the propagation of sound waves. Punching holes in the low pipe position can help remove moisture from the pipe, ensuring that sound waves can pass through the pipe unimpeded.
Reduction of air bubbles: During the concrete pouring process, air bubbles may form in the acoustic tube. These bubbles affect the speed and intensity of sound waves. By punching holes, air bubbles can be helped to escape, which improves the quality of the sound wave transmission.
Enhanced Acoustic Coupling: Drilling can increase the contact area between the acoustic tube and the surrounding concrete, thereby enhancing the acoustic coupling effect, allowing sound waves to be transmitted from the acoustic tube to the concrete more efficiently.
Improved detection accuracy: When inspecting concrete quality by acoustic transmission, the propagation path of the sound wave and the quality of the received signal are critical. By punching holes in the low tube position, the propagation path of the sound wave can be optimized, and the accuracy of the inspection data can be improved.
