How to Ensure Good Acoustic Insulation – 6 Steps

Poor sound insulation can turn a dream house into a real nightmare! Often an apartment that looks fantastic at first glance hides a poor sound insulation work.


In the case of a house of shows, the problems of sound insulation can have even more serious consequences than in the case of housing, because it is not only the quality of life that is concerned, but the very sustainability of the space.


Next, we explain the 6 essential steps to ensure that your work has a good isolation.




Step 1 – Analysis of the work

The first step towards good sound insulation is the analysis of the work environment. In this first phase, a specialized team will carry out the measurements on the spot.


It is also at this stage that the “acoustic map” can be made. This acoustic map is a document that informs the noise levels of the region in which the sound sources and their respective sound powers are identified.

In this initial analysis, it is very important that information on minimum sound insulation defined by law is included.


Step 2 – Product Definition

In the product definition phase the areas that will receive acoustic solutions are defined.


It is necessary to develop an architectural design, which includes the sound equipment and the intended use for each environment. With this information, the acoustic engineer can perform sound insulation calculations. At this stage, you can (and should) ask the acoustic engineer for innovative and sustainable solutions.


Step 3 – Identifying problems and finding solutions

The third step will be to compare all the complementary plants, mainly of hydraulics and air conditioning, with the acoustic plants. The problems identified are dealt with immediately, and sometimes a team of professionals from different specialties is needed to find the best solutions.


Step 4 – Executive Project

In this phase, the specificities of all acoustic solutions are detailed – specifications of the materials and technical design of the equipment. With the development of the executive project, the client will be able to prepare budgets with the suppliers of materials. It is at this stage that the anti-noise windows, or the so-called acoustic windows, will be specified.


Step 5 – Project Delivery

In the fifth step, the project is presented to the final customer and questions are answered to proceed with the construction phase. Sometimes some material suppliers request the design so that they can, in turn, design auxiliary equipment support systems or coating panels.


Step 6 – Work and post-work follow-up

The last stage is decisive to guarantee the quality of services. The work is only successful if it follows what was defined in the design phase. Therefore, measurements of noise levels inside the rooms, from one room to another, and from a room out are essential.


Only trained professionals with the appropriate equipment can perform the necessary tests and measurements.
