Acoustic design

Ordering acoustic design of premises, architecture, cinemas, offices and other premises is important to achieve sound isolation and amplification. In addition, the selection of cladding and planning of the features of the room are carried out, equipment is placed, and the necessary elements are selected. Basic tasks include:

· depends on the area, reverberation time, location. Indicates signal and speech intelligibility;

· the reverberation time is influenced by materials and the volume of the room; materials are selected taking into account the necessary data, and modeling is carried out;

· sound pressure. Data from all points is taken into account and is important for determining volume;

· data on the loss of consonants. Indicated as a percentage.

Indicators for reflected and direct signals and musical brightness must be calculated. All these parameters are important for creating the necessary conditions for the operation of equipment and its selection.

Classrooms and other premises receive not only a suitable interior design, but also sound requirements. When designing, the initial parameters and set goals are taken into account. Basic steps:

1. Checking the room for the characteristics of the propagation of sound waves.

2. Search for areas that need adjustment.

3. Selection of current finishes to eliminate shortcomings.

4. Formation of a map of sound distribution at different frequencies.

It is important to carry out all stages gradually, without neglecting any one. This will result in the best design solution possible.

In order to form the correct design, a three-dimensional layout is needed; the paper includes a complete list of the necessary connections and materials. Initially, a consultation takes place, then an inspection of the premises, then the development of individual solutions. Design elements for a home theater will differ from those intended for an office or auditorium, but the project usually includes the following:

· constructive solutions for windows and doors;

· decor and finishing, panels made of foam rubber, wood, and other materials with acoustic qualities;

· engineering systems providing sound protection;

· choice of curtains;

· furnishings for the room;

· lamps, sconces, other devices;

· other design elements.

All of them have an impact on sound comfort, so they are taken into account by specialists to achieve the desired sound performance.

Each building has its own norms and standards, including restaurants, home or commercial cinemas, assembly halls, and so on. In order for the result to be ideal, you need to carry out the correct engineering layout and correctly position sound-absorbing materials. Our specialists rely on standards and will create a sound distribution project, ensuring the required indicators. Compliance with standards is important for the comfort of neighbors, ensuring sound insulation and obtaining sound with maximum quality.

GOSTs, documentation regulating work on acoustic design
For cinemas, auditoriums, offices, materials are selected individually, each customer receives a contract for the formation of a design project, estimates, cost data, and so on. Calculations are performed in accordance with GOST: for auditoriums and other areas for speech intelligibility, sound insulation, measurement methods, surrounding structures and other points.

Input parameters for calculation

After checking the premises, a deal is concluded; the cost agreement specifies all the necessary work. Their implementation is agreed with the customer. Additions can also be provided at the customer's request. To create the necessary conditions, the parameters are checked using special equipment.

Sound absorbers and diffusers are used. Often, soundproofing panels are chosen for this purpose; they are especially relevant for combining decent appearance and sound insulation. Materials are produced in different textures, colors, and sizes, so you can find a solution for any request. Current:

· wood fiber panels;

· perforated plasterboard;

· glass magnesite;

· acoustic relief foam rubber;

· magnesite boards made of wood fiber base.

Materials should be selected individually, taking into account the characteristics of a particular room. This work should be entrusted to a specialist.
