How to understand the sound absorption performance of wood sound-absorbing panels

Answer】Some general knowledge about sound-absorbing board, 1. itself wood sound-absorbing board is an ordinary medium-fiber density board; 2. back paste sound-absorbing non-woven fabric or glass fiber felt-based; 3. then there is a large number of sound-deadening cotton structure inside; 4. the surface of the decorative surface is divided into melamine and wood veneer; 5. in the process of installing sound-absorbing board must leave 5CM empty; 6. 2440 * 129; 7. not Easy to be reflected out; 8. Once the sound enters the hole; sound-absorbing board hundred questions and answers sound-absorbing board knowledge popularization

How to understand the wood sound-absorbing board sound-absorbing properties, wood sound-absorbing board general knowledge daily new knowledge is acoustically a structural sound-absorbing material, itself wood sound-absorbing board sound-absorbing board basic knowledge Q&A is an ordinary medium-fiber density board, is through the thought that according to the acoustic principle to change its structure to change its finish of a sound-absorbing board.

The decorative surface is divided into melamine and wood veneer, decorative fireproof board and so on. The backing is mainly made of acoustic non-woven or glass fibre felt.

The structure of wood acoustic panels can also be divided into slotted acoustic panels and pure perforated acoustic panels.

Wooden sound-absorbing panels have the following specifications: 2440*129/195*12/15/18.

The installation method is relatively simple: the thickness of the side of the density board is used to open into a concave and convex slot to splice.

Generally speaking, in the process of installing sound-absorbing panels, a 5CM cavity must be left at the back, so that the sound-absorbing properties of the grooved wood panels can be better utilised rather than being fixed directly to the base plate.

So why is a simple wood acoustic panel able to absorb sound by changing its structure?

Common understanding is: sound through the sound wave propagation, encounter sound-absorbing board, usually sound-absorbing board surface hole is small, the back of the hole is large, once the sound into the hole, not easy to be reflected out, and then there is a large number of sound-deadening cotton structure inside (sound-deadening cotton principle sound and sound-deadening cotton in the process of propagation, and sound-deadening cotton friction, and then the sound energy will be converted into heat or kinetic energy, equivalent to we are inside the quilt Speaking, outside sound a little bit of reason is the same, why we are everywhere in the winter is snow will feel particularly quiet is also the same reason, sound energy is transformed) so as to achieve the sound-absorbing effect, it can be said that the wood sound-absorbing panels are common sound-absorbing products in sound-absorbing materials.

【Question】Insulation and waterproof roofing panels?

【Answer】Insulation and waterproof roofing panels are self-waterproof roofing panels made in prefabricated factories, which can be sprayed with colourful paint on the surface. This board consists of steel frame edge ribs and waterproof layer, heat insulation layer and fiber or steel wire.

Scope of use: one type of roof panel for mesh frame (steel mesh frame structure and other small span steel roof frame supporting use); another type of roof panel for large span (>4m) and steel roof frame supporting use. Board to the direction of multi-functional development (from waterproof to waterproof, decorative, use function combination), waterproof materials to the waterproof technology of the composite direction (the combination of different materials, such as color plate and glass), roofing form to the complex development and extension.
