Sound Insulation and Noise Reduction Effect of Aluminum Honeycomb Panel and Perforated Aluminum Plate

In the building decoration industry, aluminum honeycomb panel is one of the most commonly used sound insulation materials. Generally, aluminum honeycomb panel is combined with metal honeycomb core, which has good sound absorption and noise reduction performance. So, which noise reduction performance is better than stamped aluminum plate? In order to compare the noise reduction and noise performance of the two, it is necessary to discuss the structure of the two.

Punched plates are also known as perforated aluminum veneer. It is made of single-layer aluminum plate. CNC punch design and manufacture their own unique punching. Speaking of noise reduction and noise reduction, the sound wave propagation path in the air is disturbed, and part of the sound wave is emitted, which has the effect of noise reduction.

Different from the stamped aluminum veneer, the structure of the aluminum honeycomb panel is relatively complex, mainly composed of a panel and a bottom plate, with a high-quality aluminum honeycomb core in the middle. The aluminum honeycomb core generally uses a regular hexagonal honeycomb structure to form a plurality of closed small spaces to prevent air flow and block sound waves. The noise reduction of the sound source of 100-3200Hz can reach 20-30 decibels, and the sound insulation effect is very outstanding.

After actual testing, the stamped aluminum panel sound-absorbing cotton and aluminum honeycomb panel have certain noise reduction performance, but the aluminum honeycomb panel has excellent noise reduction performance and is often used in large high-end concert halls, night KTV, conference rooms and other places. Of course, the cost is also relatively high, especially for aluminum honeycomb panels, which require welding angle iron chassis during installation, and the cost of accessories and labor is high.
