Do acoustic panels reduce noise?
Acoustic panels are an effective solution for improving sound quality in various spaces, and one of their main functions is to reduce echo and reverberation. However, their ability to reduce noise depends on several factors, such as the type of material, the design and the configuration of the space.
Echo reduction with acoustic panels
Acoustic panels are primarily designed to reduce echo and reverberation in a space. This phenomenon occurs when sound waves reflect off hard surfaces, creating a noisy and annoying environment. Acoustic panels absorb these waves and minimise reverberation, creating a more balanced sound environment.
Acoustic panels can also be effective in reducing noise by improving the acoustic quality within a space and minimising reverberation. However, their ability to block outside noise depends on the specific characteristics of each panel and its implementation.
How much noise can acoustic panels reduce?
Acoustic panels have the ability to reduce between 5 and 15 decibels (dB), depending on their design, material and thickness. This variability is due to the fact that acoustic panels not only absorb sound waves, but also diffuse them, which helps to reduce unwanted sound in the space.
However, it is important to note that the exact noise reduction depends on a number of factors, including:
• Type of panel:
Some materials and technologies offer higher sound absorption at certain frequencies.
• Panel thickness:
A thicker acoustic panel generally has a higher sound absorption capacity.
• Location of the panel:
Placing acoustic panels in strategic locations within a room maximises their effectiveness.
Examples of efficient and effective acoustic panels
RENE and MILETO acoustic wall panels, manufactured with a recycled PET felt core, are examples of products designed to provide the highest level of sound absorption (Class A), according to ISO 354.
Their thickness and structure with recycled PET core, foam and acoustic fabric mitigate sound across the entire audible spectrum, from the lowest to the highest frequencies.
These panels are highly effective in reducing excessive echo, which contributes to creating quieter and more comfortable environments, whether in offices, restaurants, event halls or any other space that requires an improvement in acoustic quality.
Acoustic calculation for greater precision
If you want to get a more accurate estimate of how acoustic panels can improve the acoustics of a space, it is advisable to carry out an acoustic calculation beforehand.
This calculation takes into account factors such as the volume of the space, the type of activity to be carried out and the acoustic solution to be implemented. Based on these variables, we will advise you on the number of panels to install in order to improve the acoustics of the space and we will indicate the final reverberation time of the space with the installation of the recommended acoustic solution.

In short, acoustic panels can reduce noise, but their main function is to reduce echo and reverberation. Although their effectiveness varies depending on the type of panel, thickness and material, technological advances have made it possible to create increasingly customised solutions that optimise sound absorption at specific frequencies. Thus, acoustic panels offer a much more pleasant sound environment in both private and public spaces, enhancing the listening experience in a variety of applications.
