Project 2561 Home Cinema Simon - Part 1: 3D Scanning and Acoustic Design


Welcome to the first part of our exciting series, "Project 2561 Home Cinema Simon." In this installment, we delve into the initial stages of transforming a home cinema, focusing on 3D scanning and acoustic design.



We begin by meticulously scanning the entire room to create a detailed 3D model. This model allows us to plan and visualize the space accurately, ensuring every element of the design is optimised for both aesthetics and acoustics.


Using the 3D model, we conduct a comprehensive acoustic analysis. This process includes pre- and post-computation predictions to understand the current acoustic environment and how our design interventions will impact the sound quality.


This initial phase sets the foundation for the entire project, ensuring precise planning and optimal design for the best acoustic performance.


Part 2: Installation Process, Finished Project and Optimized Frequency Response


Our team carefully installs the acoustic panels, utilizing laser guides for precise alignment. The ArtNovion FixArt Frame Components and Siena absorbers are strategically placed to optimize sound quality.


The final setup features beautifully integrated acoustic panels and a sleek home cinema design. The room is now perfectly balanced, providing an immersive audio experience.

The installation process brings our designs to life, resulting in a stunning home cinema setup that combines aesthetics with superior sound quality.

The "Before Treatment" frequency response graph shows the room's acoustic response prior to any acoustic treatment. The graph highlights several peaks and dips across the frequency spectrum, particularly in the low-frequency range, indicating an uneven and imbalanced sound profile. These anomalies can lead to boomy bass and a lack of clarity in the mid and high frequencies.

The "After Treatment" frequency response graph illustrates the room's acoustic response following the installation of acoustic treatments. The improvements are apparent, with a smoother and more balanced frequency response. The peaks and dips have been significantly reduced, resulting in a more accurate and natural sound reproduction across all frequencies.

The "Before Treatment" RT60 graph depicts the reverberation time across different frequencies in the room before the application of acoustic treatments. The RT60 times are notably high, particularly in the low and mid frequencies, indicating a prolonged decay of sound. This excessive reverberation can cause a cluttered and echoey sound environment, affecting speech intelligibility and overall clarity.

The "After Treatment" RT60 graph shows the reverberation time across different frequencies in the room after the installation of acoustic treatments. There is a significant reduction in the RT60 times, especially in the low and mid frequencies, indicating a quicker decay of sound. The room now has a more controlled and balanced reverberation, leading to improved clarity, definition, and overall acoustic quality.

The "Before Treatment" waterfall plot shows the room's resonant frequencies and their decay times prior to the installation of acoustic treatments. Notice the pronounced and prolonged resonances in the low-frequency range, indicating significant bass buildup and modal ringing. These peaks and extended decays are common issues in untreated rooms, leading to a muddy and unclear sound.

The "After Treatment" waterfall plot displays the room's resonant frequencies and their decay times following the installation of acoustic treatments. The improvements are evident, with a marked reduction in the intensity and duration of low-frequency resonances. The bass response is now tighter and more controlled, contributing to a clearer and more defined sound overall.

The "Before Treatment" spectrogram illustrates the frequency response and reverberation characteristics of the room prior to acoustic treatment. The graph shows significant energy lingering at various frequencies, particularly in the low and mid-bass regions. This prolonged decay time, known as ringing, affects the room's clarity and speech intelligibility.

The "After Treatment" spectrogram reveals the frequency response and reverberation characteristics of the room post-acoustic treatment. The treatments have successfully mitigated the ringing, especially in the low-frequency range. The spectrogram now displays a more even and quicker decay of frequencies, resulting in improved clarity, definition, and overall sound quality.

We conducted a thorough pre-design acoustic analysis to understand the room's acoustic characteristics. The initial graphs show the client's home cinema system setup with its frequency response and balance issues.

After implementing our custom design, the optimized graphs demonstrate significant improvements in frequency response and balance, creating a more immersive and balanced audio experience.


Part 3 Reverberation Comparison - Acoustic Results Unveiled


In this segment, we compare the acoustic results before and after our treatment. The room's reverberation times have significantly improved, eliminating the echo effect and creating a more balanced and less chaotic sound environment. The speech is now much more intelligible, and the music and sound effects exhibit increased clarity and definition. The bass frequencies are tight and controlled, offering a better balance with the mid and high frequencies.

Part 4: Artnovion Sub Bass Trap Review


 In the final part, we review the Artnovion Sub Bass Trap Standalone and its impact on the room's acoustics. This product plays a crucial role in managing low-frequency sound energy, enhancing bass control, and balancing the overall sound profile of the home cinema. The review includes a detailed look at the 3D design integration and the final project pictures, highlighting the aesthetic and acoustic improvements achieved.
