How To Make A Stadium Soundproof?

Why does stadium acoustic design matter?

Imagine being in a stadium for an event and all you hear is noise instead of exciting sounds about the event, does that make your experience less enjoyable?

Whether it's a venue for a sporting event or a touring venue. One thing is for sure about stadiums - You can't leave the sound. Maybe it's the cheering of the crowd or the music being played. Whatever it is, it is certainly one of the most important parts of the stadium environment.

Many stadiums are also multi-purpose spaces used occasionally for concerts, performances, or other gatherings. The stadium can generate noise that can make communication and concentration difficulties, and in severe cases can lead to hearing loss.

Therefore, treating a gymnasium with decorative acoustic panels can be of tremendous benefit to all participants.
 

What factors affect stadium acoustics?

Maintaining sound rather than the noise in a spacious stadium is a difficult task.
Many factors affect the sound transmission, and proper handling is what improves the stadium atmosphere.
 

●  Stadium Space

The size of a stadium has a major impact on acoustics. We all know that the farther a person is from the source of the sound, the weaker the sound will be. There is no doubt that the larger the stadium,  the more distant the area weaker the sound.

●  Equipment

The quality of stadium sound has a lot to do with the quality of the equipment used to produce and project the sound. If a poor sound system is used, the audio may sound muffled or crackling.

●  Materials

The materials in a stadium will have a significant impact on how sound waves travel through it. Sound can travel directly from the source to the ear, but sometimes sound bounces off other materials along the way. Some materials, such as wood and metal, are great for reflecting sound waves, but clothing is a heavy absorber.

●  Video Synchronization

As more and more stadiums use video boards, light and sound travel at different speeds, and it is inevitable thing that the sound will not be synchronized with the picture. This fact also means that stadiums need to synchronize their video and audio in order to create a better experience for most people.

 

Understand the acoustic design of the stadium

Acoustical characteristics of the stadium

Due to the large space of the stadium, it is necessary to rely on electro-acoustic equipment to meet the acoustic requirements.

According to the conventional functions and usage of the stadium, the main direction of sound quality design is: to control the reverberation time in the hall to prevent acoustic defects when the background noise meets the space requirements.

Acoustic indicators of the stadium

There are two types of architectural acoustics indicators for gymnasiums, namely background noise and reverberation time.
 

●  Background noise  

The background noise shall not exceed the corresponding spatial background noise limit. The noise control design in the gymnasium shall take measures in terms of overall design, layout, and sound insulation, sound absorption, and noise reduction of the building.
               

●  Reverberation time

The specific reverberation time should be determined according to the volume of the competition hall.
 

Arrangement of acoustic materials of the stadium

Different soundproof acoustic panels are used in different positions of the gymnasium to make the effect more obvious.
For example, the sidewalls, rostrum, and referee's stand need to be treated with strong sound absorption, and the specific situation should be analyzed in detail based on the real venue.

 

What are the soundproof acoustic panels used in the stadium?

Grooved acoustic panels

In order to avoid flutter and echo, strong acoustic materials are generally arranged on the parallel sidewalls of the stadium.

The grooved wood sound-absorbing board uses the structure of slotting on the surface and perforation on the back to change and control the sound emission to achieve a good sound absorption effect.

Base material characteristics

●  Safety and fire protection

The base material has the highest sound-absorbing board fire rating.

●  Environmental friendly

It has the fragrance of natural wood, and the solid wood base material has very low formaldehyde content, which meets the national environmental protection standards. Product also.

●  Simple and natural

Both have natural wood grain and provide good visual enjoyment. Natural wood grain, patterns, and other decorative effects can be used as required.

●  Technology Industry

A variety of materials are based on acoustic principles, are reasonably coordinated, and have excellent noise reduction and sound absorption performance.

 

Ceiling space absorber

The ceiling of the stadium is prone to sound focusing. It is necessary to take effective sound absorption treatment in architectural acoustic design.

Space sound absorbers are mostly hung on the top of the building space. The inside of the Ceiling space absorber can be filled with porous sound-absorbing materials such as glass wool and rock wool.
