Sound-absorbing solutions and materials for conference rooms

In this era, in order to negotiate and deal with various business and government affairs issues. No matter the government, school, enterprise, or company will choose some multi-functional meeting rooms for meetings. However, if the sound construction is not done well before the interior decoration, then the indoor echo and reverberation will seriously affect the normal holding of the meeting. This is also a problem we often encounter. The leaders on the stage are eloquent, but the people who step down cannot hear what the leaders on the stage are talking about amidst the “buzzing”. Therefore, indoor acoustics is the most important thing. How to eliminate indoor echo and reverberation is a very annoying thing. Here are some simple sound building solutions for you.

Sound-absorbing panels

In the acoustic decoration project, in order to cooperate with the sound system to obtain a good overall sound effect, the acoustic design and treatment of the hall are very important. However, people have many ambiguities in today’s decoration projects, so that the sound effects of halls decorated with huge investment are often difficult to achieve the expected purpose, leaving a lot of regrets. The following is a brief explanation of how to carry out acoustic decoration design and disposal:

First of all, in order to achieve a good hall sound quality, a good acoustic decoration is a prerequisite. Secondly, it is the role played by the sound system and equipment. That is to say: decoration design and construction must carry out strict and scientific “acoustic decoration” and meet the requirements of relevant professional indicators in order to ensure good sound quality. However, Party A and the decorator tend to ignore the importance of “acoustic decoration”; decoration is often limited to simple soft package treatment, thinking that this is enough. In fact, this is far from the real acoustic decoration. This will inevitably lead to poor sound quality in the hall (no matter how expensive the electro-acoustic equipment is, the sound effect will not be good!). The decoration party has not fulfilled its obligations, and often makes the electro-acoustic system design and builder take the blame, causing unnecessary entanglements.
Architectural Acoustics Index Request (Acoustic Renovation Request):
1. Background noise: less than or equal to NR35;
2. Sound insulation and vibration isolation measures: There should be good sound insulation and vibration isolation measures in the hall. The sound insulation and vibration isolation indicators are in accordance with GB3096-82 “Code for Environmental Noise in Urban Areas”, namely: 50dBA during the day and 40dBA at night;
3. Architectural Acoustic Index
1) Resonance, echo, flutter echo, room sound standing wave, sound focusing, sound diffusion;
Building doors, windows, ceilings, glass, seats, decorations and other equipment in each hall must not have resonance phenomena; there must be no defects such as echoes, trembling echoes, room sound standing waves, and sound focusing in the halls, and the sound field diffusion should be even.
2) Reverberation time

Reverberation time is the main index to be controlled in acoustic decoration, and it is the essence of acoustic decoration. Whether the hall sound quality is beautiful or not, this index is the decisive factor, and it is also the only hall acoustic parameter that can be measured by scientific instruments.
