Room experiment

Specialists in acoustic work decided to conduct an experiment, which is aimed at correcting the acoustics. To carry out their plan, they chose a meeting room. For a general concept, it is important to know that the length of the room was slightly more than 6 m, the width was 4.5 m, and the height reached almost 3 m. If we consider the total area of each surface, then in total it was 116 m, and the volume of the room was 79, 6 m

The room had drywall walls, and the ceiling was made from an Armstrong hanging system. The floor is laminate and the reverb time is 2.5 seconds. The main difficulty was that there was a long echo, and that there was no acoustic comfort in the room. To solve the shortcomings, the specialists decided to use acoustic panels.

RESULTS

After the experiment, the result was obtained, which indicated the effectiveness of the use of acoustic materials. Graphs were drawn that showed the reverberation time, which was before the adjustment was made, and after it. So that you understand how it all happened, we suggest that you consider the course of the experiment:

• Initially, the false ceiling panels were replaced with sound-absorbing panels. This is necessary in order to rid the room of the "ringing" and the echo disappeared. Acoustic discomfort also disappeared. The reverberation time was 1.4 seconds;
• Further, sound-absorbing materials were used to cover the walls. The result is excellent room acoustics and clear speech intelligibility. The reverberation time was 1.2 seconds;
• The walls were painted with special acoustic panels. As a result of the work, the specialists received the correct direction of sounds, a comfortable acoustic environment and good speech intelligibility. Reverberation time - 1 second;
• At the final stage of work, all walls were treated with panels. This allowed us to get a muffled room, reduce the sound intensity, get excellent intelligibility of speech and sounds, and bring the reverberation time closer to 0.8 seconds;

As a conclusion from the experiment, it became clear that the use of high-quality acoustic materials allows you to achieve the desired result. Therefore, you should not save on the purchase of materials or on finishing work, since only high quality materials give the desired effect.
