Project: Listening studio for SuperSound, the official Adam Audio listening center
Location: Warsaw
Scope of work: Pre-construction measurements, acoustic simulations (geometric and FEM), design of acoustic treatment and insulation, supervision of installation, post-construction measurements

Introduction
SuperSound, a renowned audio retailer, aimed to create a professional listening studio that meets the highest standards and allows customers to objectively and accurately evaluate the products available in the store. The project required precise measurements, advanced simulations, and innovative acoustic solutions to achieve optimal listening and recording conditions.
Scope of work and execution
- Pre-construction measurements
We started by conducting detailed acoustic measurements of the designated studio space. This included reverberation time, sound distribution, and existing sound insulation levels. The analysis identified key challenges, such as a low ceiling and a hard tiled floor, which could negatively impact sound diffusion. Based on this, we outlined the necessary adjustments to meet the EBU Tech 3276 standards for high-quality listening rooms.

Studio space before the start of the project
- Acoustic simulations: geometric and FEM
We performed geometric and finite element method (FEM) simulations to predict how sound would behave in both rooms of the studio. These simulations helped us optimize the design to address acoustic challenges, particularly regarding low ceiling reflections and floor reflections.

- Studio layout: two specialized zones
The studio was divided into two acoustically optimized spaces:
- Control room – designed for accurate reference listening, featuring a flat frequency response and a reflection-free zone.
- Vocal booth – optimized for microphone testing and high-quality voice recordings, ensuring a controlled sound environment suitable for narration and vocal sessions.
- Acoustic treatment and insulation solutions
Despite architectural challenges, we implemented specialized acoustic solutions to eliminate unwanted sound artifacts. The key design elements included: Partition wall with acoustic doors between the control room and the vocal booth, featuring a multi-layered structure for high sound insulation performance.
- Fabric tensioning systems, concealing custom-calculated acoustic panels, ensuring both aesthetic integration and effective reflection control.
- Tuned membrane traps and resonant absorbers, optimizing low-frequency absorption, resulting in a resonance-free sound environment.
- Acoustic ceiling island and a carefully selected rug, further enhancing the reflection-free listening zone in the control room, ensuring an accurate sound representation for critical audio evaluation.

- Supervision and post-construction measurements
During the installation of acoustic treatment, we monitored the installation process to ensure precision in execution. Final acoustic measurements confirmed that the studio met strict professional audio standards, ensuring accurate listening conditions and high-quality recordings.

- Conclusion
The SuperSound listening studio was successfully completed, achieving acoustic parameters exceeding expectations. The studio not only complies with EBU Tech 3276 listening standards, but also provides an ideal space for professional recordings. Despite architectural limitations, advanced acoustic treatments transformed the space into a high-performance environment, catering to the needs of the most demanding audio professionals.
Following the project’s completion, the exceptional acoustics of the studio was recognized by Adam Audio, a leading German manufacturer of professional studio monitors. As a result, the space was officially designated as an authorized Adam Audio listening center.
