The conference room audio system is a standing equipment in the conference room, but many conference room audio systems will have audio interference when using, that create a great impact on the use of the audio system. Therefore, the reason of audio interference should be actively identified and solved. The power supply of the room audio system has problems such as poor grounding, poor ground contact between the devices, mismatched impedance, unpurified power supply, the audio line and the AC line are in the same pipe, the same ditch or the same bridge, etc., which will affect the audio signal. Clutter interferes, forming a low-frequency hum. In order to avoid the audio interference caused by the power supply and effectively solve the above problems, there are the following two methods.

1. Avoid devices interfering with each other

Howling is a common interference phenomenon in conference room audio systems. It is mainly caused by positive feedback between the speaker and the microphone. The reason is that the microphone is too close to the speaker, or the microphone is pointed at the speaker. At this time, the empty sound will be caused by the sound wave delay, and screaming will occur. When using the device, pay attention to pulling the device away to effectively avoid audio interference caused by mutual interference between the devices.

2. Avoid light interference

If the venue uses ballasts to start the lights intermittently, the lights will generate high-frequency radiation, and through the microphone and its leads, there will be a “da-da” audio interference sound. In addition, the microphone line will be too close to the light line. Interference sound will also occur, so it should be avoided. The microphone line of the conference room sound system is too close to the light.

When using a conference room sound system, audio interference can occur if care is not taken. Therefore, even if you use a first-class conference room audio system, you should pay attention to some things during use. As long as you can avoid interference between devices, power interference and lighting interference, you can effectively avoid all kinds of interference noise.

Let’s talk about conference room sound systems!

With the rapid development of science and technology, various changes have been added to people’s travel, thinking mode and information exchange, most of which are positive and progressive, which can bring greater convenience to our work and life. The meeting room is a key place for people to communicate. From another perspective, the meeting room is also a place where wealth is created. Therefore, the supporting facilities and functional design of the conference room are very important. A good conference room can greatly improve the efficiency of communication and create more value. With the development of science and technology, it brings a sense of intelligence to all aspects of our lives. So what kind of conference room should a smart conference room be?

1. The function can meet the conference needs;

2. Adopt digital hardware configuration, good system compatibility, good expansibility, and simple operation;

3. Can maximize or help participants improve communication efficiency.

With the rapid development of information technology in today’s society, the amount of information in modern multimedia data conference rooms is becoming more and more abundant, and the ways of disseminating information are becoming more and more diverse.

The design of the sound reinforcement system should fully integrate the characteristics of the conference room, and the decoration inside and outside the conference room should be harmonious. Viewed from the wall, the shape and material of the floor and ceiling are required to be carefully identified during the design. Meeting rooms with good hearing requirements should meet the following requirements:

Ensure that the sound reinforcement system has high sound clarity. The system has sufficient dynamic range and sufficient sound pressure level. There is no obvious echo, flutter echo, sound focusing and other timbre defects in various parts of the conference room. The sound transmission gain index of the system is good, and there is no obvious acoustic feedback. The timbre is naturally facsimile, ensuring that every audience part has the same frequency response characteristics.

Sound reinforcement system Sound reinforcement includes a range of symmetrical coverage of the audience area.

1. The system equipment configuration conforms to the multi-function regulations.

2. Various noise indicators of the system machine in routine use are lower than the required limit.

3. The appearance of the speaker is elegant and beautiful, without affecting the overall style and safety of the venue.

4. In the event of a fire, the sound reinforcement system can be automatically removed and transferred to the fire emergency broadcast.

The functional characteristics of the conference room are mainly language, and the language rules should have good clarity and symmetry. Based on the above, in order to create a top-level language living room, it must have good oxidation, high fidelity and sufficient dynamic space.
