Scope of work
Measurement of sound levels during vocal practice, analysis and simulation of various insulation options, acoustic insulation design, supervision of the implementation of the box-in-box system.
Introduction
The goal of the project was to create conditions that allow for unrestricted vocal practice at any time of day without disturbing neighbors in a multi-family building. The key challenge was to minimize sound emission while maintaining acoustic comfort inside the room.
Scope of work and project timeline
- Sound level measurements
At the beginning of the project, we conducted detailed measurements of the sound levels generated in the room during vocal practice. The results allowed us to determine the required sound insulation performance of the partitions – walls, ceilings, and floors.
- Acoustic insulation analysis and simulations
Based on the measurement data, we performed acoustic analyses and simulations of different partition designs, comparing the soundproofing effectiveness of various wall, ceiling, and floor constructions.

- Acoustic insulation design
Following the analysis, we decided to implement a box-in-box system with independent walls, ceilings, and floors. We developed a detailed acoustic insulation design, including technical drawings, construction details, and assembly methods.
- Implementation and supervision
The installation of partitions was carried out under strict supervision, ensuring precision and eliminating acoustic bridges. The independent structure of walls, ceilings, and floors was decoupled from the existing building, significantly reducing sound transmission.

- Results and conclusion
After the completion of the work, we conducted control acoustic tests, which confirmed the effectiveness of the applied solution. As a result, the room meets the required acoustic performance, allowing for comfortable vocal practice without disturbing the surroundings.
