What do I need to pay attention to in the acoustic design of the gymnasium?

The acoustic design of stadiums requires attention to sound reinforcement. The basic principle of sound reinforcement system design is to ensure the clarity of the sound reinforcement in the venue, that is, the sound should be clear and the audience can hear clearly. The national industry standard "Gymnasium Acoustic Design and Measurement Regulations".

If you have any other questions, please call us for consultation. Guangzhou Saijia Acoustic Lighting Engineering ****, has been doing acoustic decoration design and construction for more than ten years. In addition to the gymnasium, we also do the acoustic decoration of the TV station's studio, recording studio (studio), theater, multi-purpose hall, electric classroom, and ** hall.

Founded in 2004, Guangzhou Runyu Acoustic Engineering Co., Ltd. is a professional and technical enterprise dedicated to the design of architectural acoustic engineering, decoration construction, and the manufacture and promotion of acoustic materials. Backed by a group of well-known authoritative experts in architectural acoustics, Runyu Acoustics has rich practical experience and first-class professional level in the design, construction, application and research and development of acoustic decoration engineering.

The company's main business scope:

1. Acoustic design, construction and construction of professional laboratories such as anechoic chambers, soundproof rooms, reverberation rooms, medical audiometry rooms and conditioned reflection rooms;

2. Acoustic consulting, design and decoration construction of professional and technical rooms such as studios, recording studios (rooms), piano rooms, etc.;

3. Architectural acoustic design, construction and decoration of public halls such as gymnasiums, conference halls, lecture halls and multi-functional halls;

4. All kinds of mechanical equipment noise control projects, including the design and construction of various computer room noise control and environmental noise projects such as sound insulation covers and sound insulation barriers;

5. Design and sales of acoustic products including sound-absorbing materials, sound-absorbing products and sound-insulating materials;

6. Design and construction of vibration reduction, vibration isolation and noise reduction engineering, and sales of vibration isolation and vibration reduction equipment.

Success Story: Maoming Huazhou Kangjing Stadium.

Among them, the indicators and requirements for sound design are as follows:

1. The acoustic conditions of the gymnasium building should be based on ensuring that the language is clear.

2. No obvious sound quality defects such as acoustic focusing, echo, flutter echo, etc.

3. The reverberation time of small and medium-sized gymnasiums should be set in the range of 500-1000Hz.

4. Sound-absorbing materials or sound-absorbing structures should be installed over the hall.

5 The glass windows around the hall should be equipped with sound-absorbing curtains.

6. A large area of the wall should be treated with sound absorption.

7. The low walls and grandstand railings around the playing field should be equipped with sound-absorbing structures, or the inclination angle and shape should be controlled.

If it is not flattened on the wall, it will be diffuse and avoid echoing.

The contents of indoor acoustic design include the selection of body shape and volume, the selection and determination of the optimal reverberation time and its frequency characteristics, the combination and arrangement of sound-absorbing materials and the design of appropriate reflective surfaces to reasonably organize the near-reflection sound.

Acoustic design should take into account two aspects, on the one hand, it is necessary to strengthen the effective sound reflection in the sound propagation path, so that the sound energy can be evenly distributed and diffused in the building space, such as in the sound quality design of the hall should ensure that the audience seats have appropriate loudness. On the other hand, various sound-absorbing materials and sound-absorbing structures should be used to control the reverberation time and specified frequency characteristics, and prevent echo and sound energy concentration. Acoustic model tests are carried out during the design phase to ** the effect of the acoustic measures taken.

Architectural Acoustics To deal with indoor sound quality, on the one hand, it is necessary to understand the influence of the size of the indoor space and the materials used on the sound field. It is also necessary to consider the relationship between the acoustic parameters of the indoor sound field and the subjective listening effect, that is, the subjective evaluation of sound quality. It can be said that the quality of indoor sound is ultimately determined by the subjective feelings of the audience.

Due to the different personal feelings and appreciation of the audience, the inconsistency in subjective evaluation is one of the characteristics of this discipline; Therefore, building acoustic measurements are taken as a study. It is also an important part of room acoustics to explore the correlation between acoustic parameters and the subjective perception of the audience, as well as the relationship between the subjective perception of indoor acoustic signals and the standard of indoor sound quality.
