The design of the stadium sound system is mainly to meet the requirements of playing a variety of music, playing and amplifying the language of the game. Secondly, to undertake some large-scale theater performances, the use function is different from hall amplification and theater amplification. It has its peculiarities. In addition to ensuring high speech intelligibility, soft sound quality, and uniform sound pressure coverage, a large amount of equipment power is also required. Therefore, the stability and reliability of use should be mainly satisfied in the scheme design and equipment selection. There are three installation methods for the speaker system in the stadium sound engineering: surface installation, concealed installation and hoisting installation. Surface mount means that the loudspeaker system is installed directly in the viewing area of the auditorium; concealed installation means that the loudspeaker system is mounted on a flat ceiling or table frame and wall; ceiling mount is the use of hooks, hooks or baskets to suspend the loudspeaker system from the ceiling or on the wall. Hoisting is divided into implicit hoisting and open hoisting. stadium audio

The sound is unobstructed and can be directed directly at the listener with minimal loss of acoustic energy. By installing and adjusting the direction, the sound radiation direction of the live speakers can be adjusted intuitively, and a more uniform direct sound can be obtained in each area of the audience. However, it is necessary to strictly prevent accidents during the installation process, and be careful not to let the speakers affect the overall shape of the hall.

The main points of concealed installation of loudspeakers in stadium sound system

To adjust the orientation of the speaker system, you will need to support people in and out of the reserved mounting holes. Ceiling mounted speaker systems can be handled in two ways. Stadium Audio Quotation Form

One is to place the speakers parallel to the ceiling. The speakers are placed directly on the ceiling, and the sound is transmitted from the ceiling to the corresponding audience. This approach is commonly used in stadium sound supply systems, subwoofer systems and scattered background speaker systems. The other is to install the speakers on the ceiling of the sound enclosure to avoid the sound energy from flat roofs escaping. The empty space on the flat top of the reflector should be large enough to leave enough space at the exit of the reflector itself according to the sound radiation angle of the speaker, so as not to affect the sound coverage of the speaker. The soundproof cover should be made of hardwood and firmly attached to the top cover so as not to cause resonance due to the operation of the speaker and spoil the sound quality of the chords.

Masks used for concealment devices are transparent to sound. The width of the decorative mesh should be less than 1/10 of the diameter of the installed speaker cone, and the opening rate of the mesh should be greater than 75%. The decorative mesh should be wedge-shaped, which is conducive to the propagation and diffusion of sound waves. Concealed installation is beneficial to the decoration effect of the entire hall, but if it is not handled properly, some direct sound energy will be lost, installation is troublesome, and adjustment and maintenance are inconvenient.
