Key factors in choosing acoustic panels to maximise their effectiveness

A sound absorbing panel or acoustic panel is an element designed to improve the sound quality in spaces. This type of panel works by absorbing sound, preventing it from propagating in a given space.

Although they do not completely eliminate noise from a space, they are highly effective in reducing sound intensity, controlling reverberations and improving the listening experience.

In this article, we will explain the factors that influence the effectiveness of sound-absorbing panels so that you can better understand how to optimise the sound environment in your spaces.

How does an acoustic panel work?

Acoustic panels work in a very simple way. Because they are made of porous materials, they absorb sound waves and prevent them from bouncing off hard surfaces in a space, such as walls, ceilings or floors.

This process, known as sound absorption, contributes to the reduction of ambient noise and greatly improves the clarity of sound within the space where they are placed.

By reducing reverberation and echo, these types of panels are ideal for spaces such as offices, coworking spaces, restaurants, conference rooms or any other place where sound control is essential.

How sound-absorbing is a sound-absorbing panel?

The ability of an acoustic panel to reduce noise depends on a number of factors, such as material, thickness, location and the number of pieces installed in the room.

Although they do not block noise in the same way as a sound-absorbing material, they can significantly reduce it. In any case, the following aspects should be considered when choosing a sound-absorbing panel:

1. Sound Absorption Coefficient (NRC)

The NRC (Noise Reduction Coefficient) measures the ability of a material to absorb sound. It is expressed on a scale of 0 to 1, where 0 means it absorbs none and 1 means it absorbs all sound. Acoustic panels typically have an NRC of 0.6 to 1, indicating that they can absorb between 60% and 100% of the sound that strikes them.

All Mirplay Acoustics acoustic panels have an NRC of 0.95 and are class A rated, ensuring high quality sound absorption, ideal for improving the acoustics of any space.

2. Environmental noise reduction

In spaces with many reflective surfaces, such as glass walls or ceramic floors, acoustic absorbing panels can reduce ambient noise by up to 50% or more, depending on the number and distribution of these.

3. Improved sound quality

Although the panels do not eliminate noise, they significantly improve sound clarity by reducing echoes and reverberations. This translates into quieter, more controlled environments.

Factors influencing sound absorption

The ability of acoustic panels to reduce noise varies according to the characteristics of the space and the actual installation of this type of element. In any case, in order to make the right choice, the following must always be taken into account:

Acoustic panel materials: The most common materials for acoustic panels are rock wool, acoustic foam and textile fibres. The more porous the material, the better its ability to absorb sound.
Thickness and density: Thicker and denser panels tend to be more effective, especially at low frequencies, which are more difficult to control.
Space coverage. To achieve significant noise reduction, it is necessary to cover at least 20%-30% of the space surfaces with acoustic panels. The higher the coverage, the better the result.
Strategic distribution: Placing panels at key points, such as opposite walls, ceilings and corners, maximises their ability to absorb sound and control reverberation.
Type of noise: Acoustic panels are especially effective for controlling internal noises, such as conversations, music or machines. However, they are not as effective at blocking external noises (such as traffic or noisy neighbours), as they are not sound-absorbing materials.

Sound-absorbing panels can significantly reduce ambient noise by absorbing between 60% and 100% of the sound waves that strike them, depending on their material and location. Although they do not block external noise, they improve internal acoustic quality by minimising echoes and reverberations, making the space more functional and comfortable.

If you are looking for a quieter, more controlled environment, these decorative panels are an effective and customisable investment that suits a wide variety of needs and spaces. Now that you know what factors influence their effectiveness, don’t hesitate any longer and enjoy more pleasant and productive environments.
