Acoustic panels: how they work and when to use them
How acoustic panels work
Acoustic panels work on the principle of sound absorption – they absorb sound waves that enter the pores of the material and lose energy due to friction. The most popular materials used for such panels are mineral wool, polyurethane foam and fiberglass . Each of them works better in different frequency ranges.
The thickness of the panels is important for efficiency. For example, 5 cm thick panels absorb mid- and high-frequency sounds well, but to reduce low frequencies, you should choose panels 10-15 cm thick. Density also plays an important role: materials that are too dense can reflect sound, while those that are too sparsely spaced can reduce absorption efficiency.
Due to these properties, acoustic panels are universally applicable in various situations.
Where to use acoustic panels
Acoustic panels are a great solution for a variety of spaces:
- In home theaters : eliminates sound reflections, making the sound clearer.
- In offices and conference rooms : improves speech intelligibility.
- Music listening rooms : ensures more accurate sound from sound systems.
- In children's playrooms : reduces noise and can be adapted to the interior.
They are especially important when using high-quality sound systems , as proper acoustics allow you to hear the full potential of the equipment.
Advantages and disadvantages of acoustic panels
Advantages :
- Effectively absorbs sound in the frequency range of 500–4000 Hz.
- Easy to install and adaptable to various interiors due to a wide selection of colors and textures.
Disadvantages :
- Less effective for low frequencies (below 250 Hz).
- Requires sufficient wall space.
- Open-pore materials collect dust, so regular maintenance is necessary.
These features will be compared with resonance suppressors in the following sections to help you choose the most suitable solution for your space.
Resonance Dampers: How They Work and When to Use Them
How resonance dampers work
Resonance dampers work on the principle of mechanical resonance , purposefully suppressing low frequencies that cause acoustic problems. They resonate at a specific frequency and effectively reduce its effects.
There are several main types of resonance dampers:
- Bass traps : Operate in the frequency range of 20–200 Hz. They are made of dense mineral wool or porous materials, so they absorb low frequencies very well.
- Helmholtz resonators : Resemble a bottleneck and absorb specific frequencies, such as 63 Hz or 125 Hz.
- Membrane absorbers : Use a flexible surface to absorb vibrations and are effective in the 40-150 Hz range.
These solutions are selected according to specific needs, taking into account the acoustic problems of the space.
Where to use resonance suppressors
Resonance dampers become necessary when low frequencies interfere with acoustics. They are particularly useful in the following situations:
- In critical listening rooms : Standing waves in these spaces can severely distort the sound. Resonance dampers help distribute low frequencies more accurately and ensure clear sound.
- In home theaters : Powerful subwoofers often cause excess distortion, making the sound unclear or “muddy.” Attenuators help maintain a balanced and clean sound.
- In small spaces : In such places, low frequencies can create strong resonances that require targeted solutions to control.
- In sound studios and mastering rooms : In these spaces, precise bass control is essential so that sound engineers can make the right decisions.
Advantages and disadvantages of resonance dampers
Advantages :
- They are very effective at dampening low frequencies , where conventional acoustic panels often fail. Problematic resonances can be reduced by as much as 10-15 dB , which significantly improves sound quality.
- Allows you to precisely solve specific problems . For example, if the frequency in the room is dominated by 80 Hz, you can use an attenuator specifically designed for that frequency.
Disadvantages :
- Size and weight : Effective bass traps can be up to 50 cm thick and take up a lot of space in the corners of a room.
- Precise positioning : Improperly installed attenuators can not only fail to produce results, but also worsen acoustics. This requires acoustic measurements and calculations.
- Price : Quality bass traps cost between €150 and €500 per unit, and Helmholtz resonators can be even more expensive.
- Limited operating range : A single attenuator only works effectively in a narrow frequency range, so more complex problems may require several different solutions.
Resonance dampers are designed to precisely correct low frequency problems, rather than the overall acoustic balance that conventional acoustic panels do. They are indispensable when it comes to solving specific low frequency problems.
Acoustic panels vs. resonance dampers: a detailed comparison
Key differences and when to use each solution
Acoustic panels are designed to reduce reverberation, while resonance dampers are designed to control low-frequency resonances. Panels work best with high and mid-range frequencies, while dampers are essential for low frequencies, where the waves are longer and require specific solutions.
Acoustic panels are commonly used to reduce echo and create a balanced sound environment, while resonance dampers are specialized devices that help control low-frequency resonances that can distort sound.
In many situations, it is best to combine both solutions: acoustic panels help ensure overall acoustic balance, while resonance dampers address specific low-frequency issues. The table below clearly shows the main differences.

| Criterion | Acoustic panels | Resonance dampers |
|---|---|---|
| Main function | Reverb reduction, echo control | Suppression of low frequency resonances |
| Frequency range | Mid and high frequency control | Bass control |
| Installation complexity | Easy assembly, simple installation | Requires precise positioning |
| Typical use | Offices, studios, home theaters | Spaces with an emphasis on bass management |
| Aesthetics | Wide selection of designs | Functional, performance-oriented |
| Space requirement | Compact, easy to adapt | Requires more space or special corners |
| Price | A more economical choice | Greater investments for specific needs |
How to choose the right solution
In order to choose the most appropriate solution, it is necessary to assess the existing acoustic problems and the purpose of the space. AUTOGARSAS.LT specialists recommend starting with acoustic measurements - they help to accurately determine whether the main problem is reverberation or resonance.
If measurements show that the reverberation time exceeds the recommended norms, the first step should be to install acoustic panels. They not only reduce echo, but also improve speech intelligibility. However, if the main problem lies in the unevenness of low frequencies, the best solution is resonance dampers.
Budget also plays a role. Acoustic panels are more economical and allow for phased installation. Resonance dampers require a larger investment, but are essential for solving specific low-frequency problems.
AUTOGARSAS.LT experts offer a comprehensive approach: start with acoustic panels to solve the main reverberation problems, and then, if necessary, add resonance dampers. This will help achieve optimal sound balance and ensure high acoustic comfort.
