Only with good acoustics
is the interior perfect

Acoustics of the space

Good design is not only what you see, but how pleasant you feel in the interior. The acoustics of the room decide whether you will be stressed or relaxed at work, whether you will hear your conversation in a restaurant or be disturbed by passers-by, also what the experience of music will be. or a movie.

How acoustics work in the interior

The speed of sound is 350 m/s, it spreads, reflects and weakens like a wave.
In a 7x7m room, a sound wave travels 350m in 1 second and is reflected 50 times (50 x 7 = 350m). At each bounce, it loses part of its energy and is partially dissipated.
The amount of disturbing noise we feel is determined by the room's ability to dampen sound when it is reflected in the wall, floor and objects. When we mute it effectively, the echo is inaudible, but without attenuation it can be more than 1s.
This means that we can hear each sound weakened for another 1 second or more. If the room is not dampened, a lot of unwanted echo noise remains in it, resulting in a feeling of stress.

The modern style of living in spacious interiors with a minimalist design suffers from a deficiency that cannot be seen but often heard.
Large hard flat surfaces only minimally dampen and scatter sound wave reflections. A long echo time is created, which creates an uncomfortable and disturbing impression.
If you feel stressed in a cafe, office or even at home, it causes sound fading and unresolved acoustics.
In doing so, it is enough to purposefully incorporate absorbers and diffusers into the interior without fundamentally changing it.

Almost complete reduction of sound reflections allows the source to be heard in a direct line without interference and delay.
Although such attenuation is ideal, it limits the design possibilities, therefore it is suitable for a recording studio or a soundproofed listening room or cinema.

 Room with one acoustic wall

The entire room does not have to be muted to adequately improve the comfort of living or working.
Placing the acoustic panels on only one wall behind the TV (pictured) will absorb the sound waves reflected from the other undamped walls. They no longer return with a delay, which dramatically reduces the fading and improves the acoustics of the room.

 OakAcoustics lamella panels create a cozy environment for a better feeling of listening to music, a better movie experience or a more pleasant environment for work and conversation.

Methods of quieting the space by limiting the echo

• sound wave absorption

• sound wave diffusion

• a combination of both

SOUND ABSORPTION absorbs unwanted reflections of sound waves

SOUND DIFFUSION breaks up and weakens sound waves

How the installation method of Oak Acoustics lamella panels affects sound absorption

The method of installing acoustic panels significantly affects the acoustic properties. Although the acoustic panel material itself has excellent properties and is completely sufficient for normal residential use, there is the possibility of improving the parameters up to the level of recording studio requirements.

The given combined graph shows the effect of the installation on sound absorption.

How to understand this graph?
The sound absorption coefficient shows how individual frequencies are absorbed from 0 to 1, where 1 is complete absorption.
When placed directly on the wall (yellow graph), high frequencies (trebles) are effectively absorbed, low bass less so because more depth is needed for them.
By installing, for example. on a grid with an air gap, the efficiency also improves for the bass (blue graph). By inserting mineral wool, e.g. RockWool also significantly absorbs bass (green graph).
It means that when installing the panel directly on the wall, especially high tones, for example children's screams, women's voices, will be significantly reduced. A deep male voice or subwoofer sounds will still come through with limitation. Therefore, it is necessary to consider the use and the reason and choose the right installation method accordingly.

How to use lamellar panels for soundproofing

Although the OakAcoustics panels themselves have good sound-insulating properties, they can be further improved by assembly.

1. Installation of the lamellar panel directly on the wall by gluing or screwing

2. Mounting on a grid with an air gap

3. Installation on a grid with a gap filled with mineral wool E.g. RockWool
In this way, maximum soundproofing properties are achieved, also suitable for a recording studio.

The impersonal feeling of a minimalist interior is often caused by bad acoustics, sound reflections, echo and fading. Therefore, in addition to visuals, it is good to think about acoustics when designing an interior design, so that the result is pleasant for everyday use.

Oak Acoustics acoustic lamella panels combine modern lamella design with functional acoustics.
