Reasons and solutions for the sound of conference room audio whistling?
Under normal circumstances, the analysis of the cause of howling needs to be combined with on-site analysis, and the more common main reasons are:
1. The walls around the conference room are made of plastic-aluminum panels and other materials to form a smooth interface, and the sound reflection is strong. The strong reflected sound enters the microphone and is amplified by the system to generate positive feedback, causing howling.
2. The speaker installation position is not good. A pair of speakers are placed in the two corners of the conference room. Since the sound emitted is equal to the height of the microphone, the direct sound or the sound reflected from the wall is easier to enter the microphone, and the whistling is inevitable.
3. The speaker is too far away from the microphone, resulting in low sound, and if the volume is increased, howling will also occur due to the limitation of sound transmission gain.
4. There is no electronic acoustic feedback suppressor in the system, which is also prone to whistling.
5. The conference room space is small and the sound wave is poorly diffused.
