Three Keys To Build A First-class Conference Room Acoustics System

- Jun 19, 2018-

The main requirements of the conference room sound system are sufficient sound pressure levels, clear speech, good sound quality, good speech performance, even sound field, and high sound transmission gain (not easy to whistle). To achieve this requirement, the design must first determine the placement, number, and power of the speakers.


The first key point: how the speakers are arranged.

When it comes to speaker arrangements, many people say that they need to make up the main speakers. In fact, the sound system of the conference room is different from the professional audio occasions such as theaters and live performances. For these venues, sound and image positioning is very important. They demanded the unity of sound and video so that the audience felt that the sound came from the stage.

For the sound reinforcement in the conference room, the most important task is to let the listener hear and hear the speech of the speaker, rather than care about where the sound came from. The way the main speakers are filled with sound boxes is not easy to achieve uniformity of the sound field. Evenly arranging wall-mounted speakers and ceiling horns is very obvious for improving the uniformity, clarity and sound transmission gain (reducing howling) of the entire conference room sound field.


The second key point: the selection of conference microphones.

For conference rooms with low requirements and little investment, we can choose to hand-in-hand conference microphones. It has simple wiring, easy installation and low investment. If the conference room audio equipment decoration, sound-absorbing treatment to do a better job, the speaker layout is appropriate, the sound field is uniform, with the hand-in-hand microphone can basically meet the requirements of sound clarity. But oftentimes, owners are not willing to spend too much money on the acoustic treatment of the conference room. Moreover, some important conference rooms for government and enterprises require high sound quality and sound effects, and require natural sound. The speaker's speech is natural and easy (doesn't speak to the microphone). These conference rooms have ample investment budgets and require high sound quality. The best choice is a stand-alone microphone. Because the environment of each conference room is different, the users are different, and the position of each microphone is different. It is necessary to be able to individually adjust the parameters of each microphone according to the use situation.


The third key point: microphone digital audio processor

A good microphone digital audio processor (commonly known as the automatic mixer) improves the sound quality of the sound system throughout the conference room, and helps to increase the sound gain.

There are many digital microphone processors (automatic mixers) on the market, noise door technology, feedback suppression technology, and so on. There has been a conference audio design consultancy company that has conducted field practical comparison tests of the mainstream digital microphone processors in the world and found that it is of greatest help to enhance the sound gain. The best effect is to use Dugan (known as the father of automatic mixers). ) technology digital microphone audio processor. Nowadays, many of the world's leading manufacturers of digital microphone audio processors and even some well-known mixer manufacturers are using Dugan microphone processing technology in their products. This technique helps us not to generate howling when we open the conference microphone (even if we open dozens of microphones at the same time). And the pickup distance can reach 50cm+.
