What is acoustics?
The word acoustic is taken from the Greek language and means to be heard, and acoustics means the knowledge of sounds, creation, reproduction, transmission, control and sound effects.
In many work environments, some noise is normal. But this amount of noise should be so much that it does not bother you. Now suppose these noises flow in your house! It is natural that no one likes to hear unusual noises outside the house while resting in their bedroom!
These sounds can pass through doors and windows and enter your home. It happens a lot, especially in today's small and non-standard apartments, you hear the sound of the neighbor's TV! Of course, you should know that hearing this sound can have only one reason, and that is the lack of work of contractors in designing and building apartments.

What is an acoustic door?
As it has been said, sounds from outside the house mainly enter the house through doors and windows. The invention of the acoustic door was a huge change in the field of interior design as well as the standardization of residential houses and offices. Acoustic door is a door that prevents the passage of sound to a large extent with the combination of soundproof materials.
The main purpose of acoustics is to eliminate unnecessary and disturbing sounds (noise) in halls and sound isolation of buildings. In the construction of acoustic doors, soundproof insulation is used with high precision. The doors are made in layers, with strong sound-absorbing insulation used between the layers.

Of course, it is not only wooden doors that transmit sound, but due to the construction of iron frames and wooden doors, these two cannot be placed on top of each other without a gap when closing the door. Rather, due to the non-materiality of the door and its frame, there is always a gap between the door and the frame, which will cause sound leakage;
The acoustic door, in addition to using insulation, uses strong and sound-proof wooden frames that make the door and the frame completely touch each other and no more sound passes through the door seam. This is another feature of the acoustic door.
One of the common ways to acousticize the door can be the touch of embroidery or the touch of the door. The following materials are used for the acoustics of the doors using the tapping method:
First-class velvet fabrics and synthetic leathers for covering the door
Sponge insulation with suitable density to isolate the surface of the door
Simple studs and pen work
Buttons of the same color of fabric or synthetic leather
In addition to creating an acoustic door, electroplated flowers for the touch of the door create a beautiful appearance for the door and make your interior decoration more attractive.
Today, acoustic doors are produced in different types. Some doors are produced as anti-theft, and some are fire-resistant, etc.
