In an era where audio quality defines consumer loyalty, Brandworks is pioneering a transformative approach to sound engineering. The company’s recent investment in a cutting-edge acoustic anechoic chamber underscores its commitment to redefining precision in audio testing, a move poised to set new industry benchmarks.
The Science Behind Silence: What Makes Anechoic Chambers Indispensable?
At the heart of Brandworks’ innovation lies its state-of-the-art anechoic chamber, a controlled environment designed to eliminate external noise and sound reflections. Inspired by global advancements in acoustical engineering such as those seen in industrial facilities like Cummins’ Acoustical Technology Center—Brandworks’ chamber employs advanced sound-absorbing materials and precision engineering. The chamber’s walls, floor, and ceiling are lined with specialized wedges that dampen frequencies as low as 50 Hz, ensuring a near-perfect free-field environment. This allows engineers to measure sound sources with unparalleled accuracy, free from ambient interference.
Compliant with ISO 3745 and ISO 3744 standards, the chamber achieves background noise levels as low as NC15 (Noise Criterion), rivaling the quietest testing environments in the world. Such precision is critical for evaluating audio products from wireless earbuds to high-fidelity soundbars ensuring they deliver crisp, distortion-free sound in real-world scenarios.
Engineering Excellence: Inside Brandworks’ Anechoic Chamber
Brandworks’ facility, one of the largest dedicated to consumer electronics in Asia, spans 240 inches in length and 142 inches in height, accommodating even the most complex audio systems. Key features include:
• Thermal and Acoustic Control: A robust HVAC system maintains optimal temperature and humidity while operating at whisper-quiet noise levels (NC35 at full capacity). This ensures consistent testing conditions year-round, critical for replicating diverse user environments.
• Modular Testing Zones: Configurable spaces allow simultaneous testing of multiple products, from compact wearables to large home theater systems.
• Advanced Measurement Tools: An array of 59 calibrated microphones and 1/3-octave band analyzers capture detailed sound profiles, enabling engineers to pinpoint even minor imperfections.
From Lab to Living Room: How Precision Testing Elevates Audio Innovation
The anechoic chamber has become the cornerstone of Brandworks’ product development process. For instance, during the creation of their award-winning Dolby Atmos soundbar, engineers used the chamber to fine-tune acoustic signatures, ensuring balanced bass and crystal-clear dialogue. Similarly, the chamber’s ability to simulate real-world environments—like a bustling living room or a quiet bedroom—allowed the team to optimize noise-canceling algorithms for their latest wireless earbuds, achieving a 40% improvement in ambient noise reduction.
“This facility isn’t just about meeting standards, it’s about exceeding them,” says Ishwar, Founder & CEO of Brandworks. “By isolating every nuance of sound, we’re crafting products that don’t just perform but resonate emotionally with users.”
The Road Ahead: Sustainable Sound and Global Leadership
Looking to the future, Brandworks is integrating analytics into its testing protocols. Our advance models will predict acoustic performance across virtual environments, slashing development cycles.
Moreover, Brandworks has launched an Incubation Center for Acoustic Research and Development in Bangalore through its ‘Open Acoustics’ initiative, democratizing access to its cutting-edge anechoic chamber. This hub empowers innovators and startups to refine audio technologies, fostering a collaborative ecosystem where breakthrough ideas are tested and scaled with precision.
Mr. Amit Banka, Director of Product Development, underscores the strategic vision: “This investment isn’t just about meeting today’s standards—it’s about pioneering tomorrow’s innovations. The chamber future-proofs our R&D, allowing us to push the boundaries of audio technology and deliver market-leading solutions.”
Mr. Tausif Ansari, GM of Product Development, highlights the technical rigor: “The precision of our anechoic chamber enables us to detect and address acoustic imperfections at a micro-level. This has been transformative for products like our noise-canceling earbuds, where even minor sound leaks can redefine user experience.”
Conclusion: Raising the Bar for Audio Excellence
Brandworks’ investment in its anechoic chamber is more than a technical milestone, it’s a statement of intent. In a market where consumers demand perfection, the ability to test with surgical precision is no longer optional. By marrying cutting-edge infrastructure with a forward-thinking vision, Brandworks is not only setting new standards for audio quality but also shaping a future where sound engineering is synonymous with artistry.
For brands partnering with Brandworks, this translates to products that stand out in crowded markets, backed by data-driven confidence. As the audio industry evolves, one thing is clear: the silence of an anechoic chamber will continue to speak volumes about innovation.
