What is the absorption panels with diffuser?

This an acoustic component that helps us to create a unique, harmonious sound in an interior space. Its inside contains acoustic cotton, which was placed in a solid wooden structure and covered with a dense acoustic silk to protect it from dusting.

internal structure of acoustic panels

The diffuser front is made for quality and durability. It is made of solid laminated wood that works great and fits perfectly in your home or workplace.

The description of the panel with acoustic diffuser:

– All our sound absorbing panels contain 90kg / m3 of acoustic cotton, which is harmless to health, enclosed in a hard wooden structure
– To further reduce dust protection, cover externally with a dense acoustic silk.
– Then finally the diffuser front panel is made of hard compressed wood.

Why do you need an acoustical paneling?

It depends on what purpose you want to use it for and what personal ideas you have. At the design stage, we always help our customers to choose the most ideal product combination, also with individual needs in mind. Our many years of experience and continuous training provide our customers with high quality and expertise at affordable prices.
There are basically two types of acoustic modules, one that dissipates sound (diffuser) and the other that absorbs. In this case, you get two in one products. Diffuser panels can contribute to improving the spatial sound of various sound materials and recordings.


Since most of our homes were not built by us, it is unlikely that the acoustics of the rooms were taken into account when designing our bedroom, living room, or even our basement. In the case of a hi-fi room, sound studio, for example, with all this in mind, a few things are taken care of from the very beginning.

It is an important fact that an absorber or diffuser is always the best tool to create a good sound in a room. Be it a professional or privately driven need.

  • home theaters
  • music rooms
  • stereo rooms
  • studios
  • but even rehearsal rooms set up in the basement require optimizing the sound of the room. Eliminate echoes and other unpleasant annoying sound effects.
Properties of acoustic diffusers

The choice of materials and design options are varied. Products are often made of wood, various plastics, metals, or plexiglass . They are available in a variety of sizes and colours, as well as a variety of qualities and price ranges.

Advantages of our unique diffuser panel:

1.We make high quality, solid and highly efficient products.
2.Thanks to the solid wall lamellas, the bass attenuation is more effective than the broadband  panels
3. In addition to sound absorption, it perfectly balances the diffusion and scattering of sound.
4. Our diffuser panels are designed to reduce the high range as little as possible, while absorbing deeper sounds more effectively than average.
5.The deep sound passing through the hardwood front panel vibrates the slats, making it even more effective as a resonator in reducing bass.
6.We continuously test our products and measure the reliability of our panels, which reduce unwanted sound waves from 40Hz to 20,000Hz.

What can a diffuser acoustic panel do in practice?

First of all, what is striking is the tiny little gaps on the front of the diffuser through which the sounds can move more freely, thus not only having a reflective but also a scattering effect.

The quality of the existing sound also improves, the reflections are divided into parts, which only reach the ear later. The effect of incorrect control (phantom sound sources) caused by strong reflections is reduced. The positive effect on acoustics is based on changes in time range, intensity, and direction.

Compared to broadband sound absorbers, our diffuser acoustic elements:

They absorb more deep sounds below 300 Hz but less sounds above 600 Hz. These effects can be calculated / simulated using professional simulation programs – as well as diffusion properties when combining different diffuser elements.

For good surround sound, strive for the lowest effective frequency possible.

Why are Perfect Acoustic diffuser acoustic elements durable and practical?

The function of the acoustic diffuser is to distribute the sound, so to speak, most efficiently. Although experiencing sound is always subjective, all students agree that, for example, the surround sound of music is a much more vivid, natural, yet softer experience. The sound field is the best possible, and its even distribution in the space eliminates the unpleasant effect when sounds appear “sharp” in the higher frequency range.

Good quality is extremely important to us!

That is why our products are filled with 90kg / m3 acoustic cotton with an extraordinary density built into a solid wooden frame that gives a strong hold, thus ensuring professional and appropriate reduction of bass. This definitely requires a high-density fibrous absorbent material or membrane that can meet expectations perfectly. Materials such as styrofoam sponge or acoustic foam should not be considered in such a special case. The cotton used by Perfect Acoustic not only provides maximum protection with the help of anti-dust acoustic silk, but is also completely harmless to health. Each diffuser front is made of durable, high-quality compressed wood, individually designed by us.


We provide pre-drilled holes in the back of our products for easier installation, although it should be mentioned that due to their significant weight, they can be placed on the ground, even on their own feet, making them absolutely mobile.

Suspension of acoustic ceiling panels-acoustic ceiling tiles:

In case of lack of space, it is not a problem to secure the diffuser panels to the ceiling either.

Either by hanging a thin chain or by hanging on a braided wire.

We are also partners in the implementation of the design you have dreamed of in terms of the construction of our acoustic elements.

Perfect Acoustic quality!

We already ship to 27 European countries!

Robust, impeccable quality and extremely efficient – the diffusion acoustic panels we offer represent the optimal and reliable quality on the market at an affordable price. Our products are present wherever the need for surround sound, professional work, and audiophile listening arises. Hand-crafted acoustic elements always guarantee the efficient distribution of sound reflections in the room and contribute to a better sound perception in the field of music and sound. The acoustic elements with diffuser in all versions allow a pleasant and precise listening experience in detail, thus providing a large and extensive surround effect. In addition, standing waves are significantly reduced, optimizing the room, and individual frequencies are more perceptible. This makes it perfect for studios, recording and control rooms, as well as cinema and hi-fi systems. Thanks to their exceptionally solid construction, the panels are robust and easy to attach to the wall or even the ceiling.

Should the echo be completely eliminated?

No place should be made a deaf room, i.e. there should always be a little echo. Values ​​specified for this echo exist. If we dim the room too much, our room will be unsuitable for quality music recording or listening.
The sound-absorbing surfaces decompose the sound waves and distribute them evenly over most of the room. This simply results in a more enjoyable listening experience.
“Natural” diffusion already takes place through various pieces of furniture (similar to absorption), such as carpets, bookshelves, plants of different sizes, and so on. In the case.

In a sound studio, which is mainly used for singing, they usually require a lot of sound absorption.
This is why it is especially important to consider the advice and recommendations of a specialist when mapping such a special needs studio.

Reducing office noise

How can you increase or rather how can you best support and help the work of office workers?

This, as we know, depends on several factors, but we will now look a little at the noise.
There are three important factors in room acoustics in the office; one of these is the environmental design of concentration work or, in the case of open-plan offices, the minimization of sound propagation. In the case of closed offices, the main goal is the intelligibility of the speech. Acoustic optimization of a room, more than noise reduction. Creating the ideal work environment can multiply the productivity of your business. With these in mind, there can be a number of benefits to using professionally used acoustic panels.

Acoustic elements have been shown to reduce stress levels in workers. At the same time, it significantly increases workplace motivation and may sound incredible, but it even increases brain capacity. The acoustic elements we offer provide the best solution for various office spaces as well.

Diffusion is the perfect companion for acoustic instruments

Acoustic instruments complete the good sound of the room and provide an unforgettable experience. An over-attenuated echo-free deaf room, or a room with only very strong echoes (low diffusion, many hard surfaces, parallel walls, worst case squares), is completely unsuitable for the ideal sounding of acoustic instruments.
Therefore, in rooms where acoustic instruments are mainly recorded, a proven and recommended ratio of about 70% diffusion and 30% absorption, although this can of course be adapted to the individual situation and personal needs.

Importance of acoustics-

home studio

Many people only care about sound absorption, but don’t take into account the fact that the necessary amount of room echo will always be maintained (and it should be!). And this “residual” reflection sounds much better if it doesn’t just consist of standing waves bouncing back and forth between the two bare walls. But if the reflection is targeted in more directions.
The echo of the applause disappears!
The (small) rooms look acoustically bigger!
The sound comes to life and is filled with energy-dynamics.

The optimal design allows for maximum performance at the best price!

When optimizing the acoustics of a room, the size of the room, the visual aspects and of course the budget must be taken into account. The 25-square-meter listening room or rehearsal room can be upgraded with the help of an absorber of up to a few square meters. Of course, in each case we make recommendations with accurate measurements and calculations when designing and selecting the right acoustic panel or bass absorber and other elements.
The corners of the room are an exception to this – because this should only be reserved for bass absorption – we offer the perfect solution for this with the possibility of using a bass trap.

The role of the bass trap for excellent sound:

Bass absorber

Bass absorbers absorb acoustic bass energy. This is essential when you think about it, not only in the world of music or cinema and theater, but also in offices or conference rooms. The sound-absorbing panel membrane, i.e. the bass traps, are extremely important for achieving clear sound. It can be used to create optimal acoustics by reducing bass. Many years of expertise and experience in the perfect execution of our self-made bass traps help our impeccable work.

Areas of application of diffuser acoustic panels in the past and today:

Quality sound is essential in concert halls, sound studios, cinemas and theaters. The use of acoustic elements was already present in the Baroque era. When building the large concert halls, and compared to the possibilities at the time, they sought to achieve significant results and placed great emphasis on achieving impeccable sound. For this, special wall structures were used at the time, combining smooth wall surfaces. This task was solved with a significant amount of decorations, rosettes and other structures on the wall and ceiling, as well as figurines on the walls and balcony. This was a well-established method at the time to increase the diffusion of sound space in a room or room.

színház akusztikaSome of these concert halls have such unparalleled acoustic properties that even today we are considered among the best in the world.
Thanks to the design of today’s lecture halls, which are much more modern and generally correspondingly simple, the use of special acoustic diffusers has become necessary. In the meantime, the use of acoustic modules and bass traps has become fundamentally natural, key, and of great importance not only in large halls but also in studios and rehearsal rooms. The goal is to create a sound field that can evenly cover the widest possible range of angles. Therefore, the structure of acoustic diffusers is designed so that the energy of the reflected sound is as good as possible from the direction of the geometric reflection and propagates evenly in all directions. It should be mentioned here that the role and application of the sound-absorbing panel membrane, more commonly known as the bass trap, is essential in the space to be optimized for sound.

The principle of modern acoustic diffusers, which is most widely used today, dates back to the 1970s, and Manfred R. Schröder is concerned with the theory of number theory diffusers based on numerical calculations. With the help of these certain mathematical operations, the properties of the acoustic diffuser became computable for the first time, relatively accurately, and quickly. These mathematical operations continue to serve as the basis for calculation and scaling. In our modern world, the accuracy of this calculation is greatly improved and supported by the use of computers.

acoustic-curtains-soundproof curtainProfessionally constructed studios, designed for the acoustics of the room, cannot be compared to a normal-sized living space. This is not to say that this cannot be remedied in retrospect, as we have dazzled our customers with our excellent ideas and practical advice in countless cases. That is why with skill, mathematical, computer analysis, and the placement of some acoustic modules, a much better sound can be achieved.
Diffusers are often attached to the back wall of a room or to reflection points. Diffusers help solve problems such as filter effects and reduce reflected echoes. We have been dealing with acoustic measurement for more than 10 years, so we know that with our experience and professional knowledge, almost any space can be tuned.
