Acoustical Engineering

Acoustical Engineering

Designing and making of a project for acoustics, soundproofing and noise isolation is necessary when it must be predicted with what exact results from the diffusion, absorption, sound isolation or abatement actions will be achieved. 

Example: The acoustic treatment, noise isolation, soundproofing of a room or space, in which the sound is from speech with 85 dB/А level and the neighbouring room is a bedroom, in which the sound level must be under 35 dB/А for the purpose of sleeping, the project calculates the losses of sound energy through the construction of the rooms and what sound isolation layers must be added for reaching this level.

The spread of the sound through the construction depends on the different physical parameters of the materials, thus the making of a project is recommended for reaching the desired effect. Important to know is that some of the most popular heat isolation materials like EPS or XPS decreases the soundproofing properties of the construction. The mass use of constructions, which create acoustical bridges, is the reason for making the calculation check up for soundproofing a recommended part from the choice of sound isolation systems.

The projects for soundproofing of rooms in residential and public buildings are done in accordance with the methodology of EN ISO 12354 -1 and 2.

For industrial noise isolation & soundproofing the project is a mandatory part for finding a solution for reaching the necessary sound levels. Many standards and methodologies are used for the calculation of the industrial sound isolation or vibration control, depending on the specifics of the root problem.  

Acoustic Project- Prioritization.

The projects in acoustics are mandatory part for determining the kind and the location of the acoustic linings in studios, concert halls, study rooms, shops, restaurants, preview theatres, clubs and offices.

For the purpose it is done in calculations and simulations of the following parameters:

  • Reverberation time RT60 and RT30
  • Evaluation of the clarity during speaking D50 and C50
  • Research of early and lately reflections
  • Speech transmission index STI
  • Background noise and general sound level
  • Modal and wave analysis
  • FFT Analysis.
  • Speech Intelligibility & Tonal Strength

In the projects are included technical details, quantifiable value calculation, 3D visualization and calculation part with XL Worksheets and other data required for verification.

The simulations are made by specialized software according to the American, British, European and international regulations and standards.
