How to Pick a Acoustic Panel Guide

I.What is a acoustic panel?

Acoustic panels are an ideal sound-absorbing decorative material, and their sound-absorbing principle is achieved through acoustic impedance matching and multiple reflections, refraction, and attenuation of sound waves. It has the advantages of sound absorption, environmental protection, flame retardant and heat insulation, thermal insulation, moisture-proof, mildew-proof, easy dust removal, easy cutting, mosaicable, easy construction, good stability, good impact resistance, good independence, high cost performance, rich variety of colors to choose from, which can meet the needs of different styles and levels of sound-absorbing decoration.

II.Purpose of acoustic panels

It is used in grand theaters, concert halls, movie theaters, recording studios, studios, listening rooms, conference rooms, gymnasiums, exhibition halls, dance halls, KTV private rooms, home movie and TV halls, factories, silent rooms, courtrooms, lecture halls, interrogation rooms and other acoustic places, sound-absorbing textile factories and factories with excessive noise, as well as sound-absorbing wall panels and ceiling panels of large public buildings.

III.Classification of sound-absorbing panels

1. Wooden sound absorbing panels

Consisting of facings, cores and sound-absorbing thin felt, it is divided into two types: slotted wood sound-absorbing panels, which are slotted and perforated on density boards or solid wood boards, and hole-wood sound-absorbing panels, which have round holes on both the front and back. Wooden sound-absorbing panels are often used in wall and ceiling decoration

2. Foam acoustic panels

A common sound-absorbing material, commonly used in places such as music recording studios, movie theaters, and conference rooms, which has the advantage of being inexpensive, easy to install and maintain, while providing good sound absorption.

3. Mineral wool sound absorbing panels

Made of natural mineral fiber, with excellent sound absorption, fire resistance and durability, suitable for all kinds of places.

4. Acoustic panels of metal

It is composed of metal plate and sound absorbing material, which has the characteristics of aesthetic, fireproof and durable, and is suitable for various places.

5. Fiberglass sound absorbing panels

Made of fiberglass, it has excellent sound absorption, fire resistance and durability, and is suitable for various places.

6. Fabric acoustic panels

The core material is centrifugal glass wool, which has excellent sound absorption properties and is commonly used in airports, stations, factories and other places.

7. Pottery Aluminum Decorative Sound Absorbing Panel

Consisting of materials such as inorganic materials and reinforcing fibers, it has the effect of fireproofing and sound-absorbing decoration.

8. Polyester acoustic panels

Made of 100% polyester fiber, it has the characteristics of sound absorption, environmental protection, flame retardant and heat insulation, thermal insulation, moisture-proof, mildew-proof, easy dust removal, easy cutting and mosaic, easy construction, good stability and strong impact resistance, with rich and diverse colors to choose from.

IV.Installation methods of acoustic panels

1. Externally, light steel keels and aluminum alloy keels are often used for the installation of sound-absorbing panels. The keel frame for the installation of sound-absorbing panels is first installed according to pre-calculated specifications, and then the mineral wool board is installed on the bracket. It is relatively simple and easy to repair and replace.

2. Hidden keel sound-absorbing panel installation generally inserts the side with the side groove into the skeleton, and the specifications of the sound-absorbing panel must be prepared according to the dimensions on the design drawing.

3. Install the flat acoustic panel on the back with glue, and then install the sound-absorbing panel, but pay attention to the flatness of the surface.

V.How to choose acoustic panels?

1. Check whether the material of the acoustic panel is qualified. First, check whether the acoustic panel has an authoritative test report. Secondly, we should also pay attention to whether the sound-absorbing panels sold by the manufacturer and the samples sent for inspection at the time of inspection are the same product

2. To test its acoustic performance, the effect of acoustic panels is not that the thicker the board, the better. There are some ordinary acoustic panels on the market that increase the thickness and weight of the wall panel to achieve the sound reduction effect. However, this kind of board has low sound insulation efficiency and takes up a lot of space, causing the wall panel to be too heavy and the installation cost to be high.

3. Look at the strength, waterproof and fire resistance of the sound-absorbing panels. While improving the sound insulation effect of the wall, you must also pay attention to some other properties of the wall, such as whether the strength of the new sound insulation wall or the sound insulation renovation of the old wall meets the requirements. If you want to hang heavier objects on the wall, such as flat-screen TVs, large oil paintings or photo frames, large decorative lights, etc It is necessary that the wall panel has a certain strength and can bear a certain weight. In addition there are waterproof, anti-corrosion, fireproof and other properties.

4. Sound insulation effect maintenance time Some acoustic panels install a rubber layer, vibration-absorbing material or sound insulation felt, etc. between the two panels. In the short term, the sound insulation effect can be improved to a certain extent but the effect will be reduced over time, and the cost is very high. The sound insulation effect of high-quality acoustic panels remains at least 50 years
