Stages of creating a sound system at a sports facility

1. Technical task

   Inspection of the facility, study of the design / engineering documentation of the building, setting goals and objectives. If you need acoustics for the stadium, leave a request in any convenient way. The company's specialists visit the site for a detailed study on site. Based on the results of the inspection and determination of the required result of the system operation, a technical task is formed. At this stage, a preliminary estimate and specification for the equipment used is drawn up.

2. Acoustic calculations

   The sound design of such a large, echoing object such as a stadium should ensure maximum intelligibility of the speech of commentators, musical accompaniment, as well as information messages during an emergency. To solve this problem, we create a 3D model of the room, where all zones of the room up to a meter are visible and calculated, the strength of the pressure of sound waves and the index of intelligibility are indicated.

3. Noise measurements

   To create a 3D model, measurements are taken in which absolute silence is created on the object. The main parameter needed to create a calculation, the reverberation time is the decay time of the echo. Rooms in which the decay time is significant are called echoing. The sounds in them are difficult to distinguish and merge into a single hum. If the reverberation time is too short, then there is practically no echo in the room, which is also uncomfortable for visitors.

   For sports facilities, there are recommended parameters, the compliance with which makes the stadium comfortable for spectators. To create an effective sound system, it is necessary to consider the appropriateness of the acoustic parameters of the room and the characteristics / quantity of equipment. To measure the reverberation time, we use special instruments - sound analyzers.

4. Interior design recommendations

   Measurements of the main acoustic parameters allow you to identify the shortcomings of a given room and determine ways to eliminate them. The technical tools allow you to model the room, taking into account the available materials and interior finishes, as well as recommend certain types of finishes to improve the sound quality.

5. Equipment selection

   Professional equipment is used for sounding stadiums and ice arenas. Only the world's leading brands. Selection of models by characteristics. Linear arrays for stands. Clustered sound systems with different mounting methods. Installation of sound masts. Horn radiators. Equipment for commentary booths: consoles, headsets, microphones, loudspeakers, volume controls. The choice of brands and models is carried out taking into account the data of the acoustic calculation, the goals and objectives of the customer, as well as the size of the budget.

6. Delivery, installation, launch

   We organize the delivery of equipment to anywhere in Russia and the world. We equip sports facilities in remote regions, regions of the Far North and other remote settlements. We deliver goods by road, rail, air and water transport. Installation can be performed on a turnkey basis, or in the installation supervision mode under the guidance of our employee. We carry out commissioning, equipment configuration, test runs.

When sounding stadiums and other large sports facilities, we draw the customer's attention to the need to include a clause on sound equipment in the project in advance. Ordering acoustics on a leftover basis will lead to a deterioration in sound quality, which means a decrease in the loyalty of spectators and the overall popularity of the stadium. Since any stadium is a bowl-shaped structure, the reverberation time here is quite significant. At the same time, it is necessary to achieve certain indicators of intelligibility of any sounds, be it music, the voice of a commentator during the competition or information messages. It is much easier to solve this problem during the construction or reconstruction of an object due to architectural solutions as well.

FIFA requirements in the field of sounding of football grounds state that the sound pressure level in the places where spectator stands must be installed must be at least 115 dB. It can be quite difficult to achieve such indicators due to the considerable remoteness of the line arrays from the fans' seats. When placing the loudspeakers under the dome (as is most often the case), the distance to the stands will be up to 40 meters. To ensure that the sound reaching the audience remains loud enough and at the same time intelligible, we use equipment of high power and narrow directivity. You can ensure maximum sound quality by "dividing" the stands into separate segments, and directing their own sound system to each.

When choosing equipment for sounding a stadium, not only technical parameters are taken into account. The equipment must be made of durable materials that meet the safety requirements for facilities with a large crowd of people. For open stadiums, equipment cases are treated with an all-weather coating. An important factor is the correct, reliable and aesthetic suspension system.

The stadium sound reinforcement system is a complex complex consisting of many acoustic solutions. Sound systems can be broadband, high-, low- and mid-frequency. Some of them are collected in line arrays. Finding the best option for a specific object is a task that GTLight specialists will solve.

System integration at a sports facility

GTLight is a system integrator in the field of LED, light, sound and digital technologies. Professional sound for a sports facility can be just one of the components of our project. The integration of several directions in the equipment of a sports facility simplifies control, allows you to create a unified control system, and optimize the laying of communications.
