Solving the inconveniences caused by exterior noises requires knowing the main types of acoustic materials that will prevent sound penetration inside homes, businesses, offices, bars, restaurants or rooms.
Insulating and absorbent materials: differences
Both absorption and acoustic insulation are essential to prevent the passage of sounds when entering or leaving a certain space. To insulate, suitable materials will be necessary that will reflect part of the energy produced outside and to absorb it there are other elements.
Some of the most important differences to consider are the following:
· Acoustic absorption: allows to control the room, reverberation and other factors that influence the acoustics of an environment, conditioning the environment with suitable materials.
· Acoustic insulation: it helps to protect the room from any kind of sound penetration and it will also prevent noise from going out easily to the outside.
If we place insulating materials such as steel, lead and concrete, among others, we will not fully achieve the main objective of acoustic insulation, because they are elements without absorption properties such as polyurethane or glass wool. Likewise, by installing absorbent elements between two partitions, it is possible to substantially improve the insulation.
Frequently asked questions about soundproofing materials
Regarding acoustic materials, the usual questions that will clear up many doubts before choosing the type and quality of the elements to isolate a space are:
Can acoustic materials soundproof?
Generally, they do not fulfill this purpose 100%, but less noise passes. For example, they prevent the noise produced by people who speak loudly in a soundproof room from being transmitted less than in another that is not soundproof, contributing to a lower noise emission.
What is the function of materials?
Reduce reverberation time and eliminate the risk of mixing noises at a specific moment.
What is meant by reverb?
It refers to the time a sound remains inside a space, for example, there is high reverberation in bars where voices mix and cause discomfort among the audience.
How to measure reverb?
It consists of a simple sound level meter test carried out by acoustic technicians to obtain exact data from the place.
Where should the materials be installed?
On walls and ceilings, the panels can be suspended and glued in different ways. There are various designs for a particular choice, currently available in various colors.
Apart from what has already been mentioned, it is said that there is a greater guarantee of the insulation functioning and the reduction of the noise level by using quality and approved acoustic materials. There are many of them on the market with their corresponding approvals and quality seals. At Gyptech Systems we are manufacturers of numerous elements and materials used for acoustic soundproofing.
