Self-supporting sound-absorbing panels

Why self-supporting sound absorbing panels are useful

Every day we frequent many environments in which many people share the same space talking all together in different conversations. Let's think of restaurants, bars, but also open space offices, or public administration places open to citizens. Then there are places dedicated to cultural activities and leisure time such as cinemas and theaters where it is very important to obtain good acoustics: when we watch the new film by our favorite director, we want to hear well what the actresses and actors are saying; if we are following the performance of a comedian, or a comedian, or a live show we pretend to understand every joke. This is where sound-absorbing materials make their essential contribution to making the experience pleasant. In particular, i self-supporting sound-absorbing panels they are useful in environments such as offices, clubs, cafes, restaurants and waiting rooms of public bodies.

When you need self-supporting partitions with sound-absorbing characteristics

Sound waves are reflected by the surfaces of the spaces in which they propagate. They act a bit like ping pong balls that bounce on the hard, smooth surface of the floor, but come to rest on the ground if dropped on a lawn. THE self-supporting sound-absorbing dividers they play the part of the lawn, i.e. they absorb sound waves, just as the lawn absorbs the kinetic energy of the ball. Structures of this type, made of special materials, are needed whenever acoustic reverberation is very pronounced in a closed environment. This phenomenon is connected to the reflection of sound waves from the obstacles they encounter.

Sound-absorbing mobile walls: divide spaces, improve acoustics

Self-supporting panels that mitigate the reverberation of sound waves can become real sound-absorbing movable walls. In this way, the dividers respond to two different needs:

• subdividing a very large space in an advantageous way;
• obtain environments with reduced sound reverberation and maximum acoustic comfort.

But in hindsight the satisfied needs are three:

• customize workplaces or reception areas for the public.

The sound-absorbing mobile walls made with the panels of Momenti they can be colored and decorated as desired: with abstract shades of color that transform into each other, light, simple or complicated geometric figures, images of nature or figures that evoke stories.

How self-supporting sound-absorbing panels are made

I self-supporting acoustic panels they are characterized by a structure that contains them like a frame and ensures that they remain stable without external support. They have a core which is covered with sound-absorbing material suitable for minimizing sound reverberation. There are several types of sound absorbing material. Each type is distinguished by specific characteristics that make it suitable for different uses.

The material

The material of which the self-supporting acoustic dividers are made has a fundamental importance in guaranteeing the reduction or even the total cancellation of the sound reverberation. In fact, it is precisely thanks to its characteristics that a sound wave can be partially or totally absorbed, without therefore undergoing the phenomenon of reflection. THE self-supporting sound-absorbing panels Momenti can be covered by:

• polyethylene and acoustic polyester;
• fiberglass.

In panels of the first type, “Acoustic Fiber” acoustic polyester is used for the cladding, while inside there is a section of “Strato Isolant” polyethylene.

Glass wool is made up of thin filaments that derive from glass processing and can also be obtained from rock. This material is characterized by a sound-absorbing power due to its porosity. It is a versatile material, suitable for any kind of venue. It is often placed within panels covered with fabric.

Porosity absorption: what it is

What is theporosity absorption? As the expression suggests, this particular case of sound absorption depends on the pores present in the sound-absorbing material. It is precisely the very numerous pores that ensure the property of the material sound absorption. Indeed, the air propagates the sound wave by vibrating. The vibrating particles are trapped in the tiny cavities of the material, their kinetic energy becomes heat and the sound is thus dissipated.
