Project 2379 HiFi Room Nick: Achieving Acoustic Excellence

Welcome to the detailed journey of Project 2379, where we transformed Nick's HiFi room into an acoustic haven. This project involved meticulous 3D scanning, precise design, and advanced acoustic optimization techniques. Here’s how we did it:

The completed installation features a blend of absorption and diffusion panels, tailored to the room's specific needs. The combination of materials and design optimizes sound quality for an immersive listening experience.

Part 1: Detailed 3D Scanning and Design

We began with a comprehensive 3D scan of the room, capturing every detail to ensure an accurate acoustic analysis. This data was crucial for creating a precise 3D model of the room, which allowed us to simulate various acoustic treatments and predict their impact.

This detailed visualization helps in planning and executing the installation process with accuracy, ensuring that the acoustic panels are optimally positioned for maximum effectiveness.

Pre-Acoustic Prediction Analysis

Using the 3D model, we conducted a pre-acoustic prediction analysis to identify potential issues and plan the optimal placement of acoustic treatments. This analysis included evaluating the room’s current reverberation times and identifying areas prone to bass buildup.

Part 2: Installation of Acoustic Treatments

With the analysis complete, we moved on to the installation phase. Our team carefully positioned Artnovion acoustic panels to address mid and high-frequency reflections, ensuring a balanced and clear sound.

Part 3: Multi-Sub Setup and Low-Frequency Optimization

The final step was the multi-sub setup for low-frequency optimization. We strategically placed multiple subwoofers to avoid nulls and mitigate SBIR (Speaker Boundary Interference Response). This configuration, combined with AVAA C20 passive bass traps, significantly improved the room’s bass response.

Results and Analysis

The results were impressive. Our post-treatment analysis showed a much smoother frequency response and reduced reverberation times, ensuring that the room met the recommended standards for HiFi listening.

Here is the client's initial setup SPL graph. Notice the inconsistencies in the bass response, which we aim to smooth out through our optimization process.

In our setup you can see the aligned multi-sub configuration. This setup ensures optimal low-frequency performance across the entire listening area.

This graph compares the SPL of the speakers only versus speakers with subs setup. The integration of the subwoofers provides a fuller, more consistent low-frequency response.

The graph compares the frequency response of the room with and without the Corsini setup. The red line represents the setup with speakers only, while the blue line shows the setup with aligned multi-sub and low-frequency optimization (Corsini setup). The Corsini setup exhibits a much smoother frequency response, with significantly reduced spatial variation, fewer peaks, and nulls. This indicates a more balanced and optimized acoustic environment, enhancing the listening experience by providing consistent sound quality throughout the room.
