What sound-absorbing panels should lecture halls use

If a large lecture hall wants to create an excellent audio-visual environment, it is necessary to use sound-absorbing panels, especially perforated wooden acoustic panels wood. The space of a large lecture hall is empty, it is extremely easy to cause sound reverberation, and the reverberation time is too long to cause sound mixing, thus affecting the auditory environment of the lecture hall during use.
 

Product parameter of perforated acoustic panels

Substrate: ordinary, flame-retardant, environmentally friendly, moisture-proof
● Veneer: Melamine, natural veneer, flame-retardant skin, spray paint, metal surface, technical imitation veneer
● Width: 600mm, 1200mm, 1220mm
● Length: 800mm, 1200mm, 2400mm, 2440mm
● Thickness: 12mm, 15mm, 18mm
● Size: Allowable tolerance, width ±1mm, length ±1mm, height ±0.2mm

At the same time, there will be more or less other acoustic problems in the large lecture hall, which will also affect the sound field environment of the lecture hall, making it difficult for participants to hear, and affecting the normal progress of the meeting. Then, to solve the problems of long spatial reverberation time and acoustic defects, acoustic design is required.

The large-scale multi-function hall project is built around the two points of sound absorption and sound insulation. Generally, when doing sound-absorbing treatment, the most used method is to install perforated wood sound-absorbing panels. The principle is to install the perforated wood sound-absorbing board on the solid wall so that the whole wall can achieve the perforated sound absorption of the wall.

The circular hole structure of the acoustic wood fiber panels is based on the principle of scientific calculation of acoustics. It has strong selectivity for the sound absorption spectrum, and has good sound absorption performance for mid-and low-frequency. For example, filling the cavity behind the sound-absorbing structure with an appropriate amount of sound-absorbing cotton can improve the mid-and high-frequency sound absorption effect.

It also is used in meeting rooms, lecture halls, multi-function halls, gymnasiums, basketball courts, school auditoriums, classrooms, piano rooms, museums, Indoor entertainment venues， and other spaces that need noise reduction.
