Creating a quiet space for electric vehicles

This specialised test ensures products remain silent in real-world use and preserves the quiet, premium driving experience of the electric era.

Consumer expectations for in-cabin comfort are rising. Electronic actuation technology (e-motion) is fast becoming a new trend in automotive interior design, making vehicles more intelligent and user-friendly. However, this also means that every detail inside the cabin can impact the overall sense of tranquility, setting higher standards for "quiet sophistication."

Southco embraces this trend by focusing on the development of high-quality electronic actuation components, including powered headrests, display mounts, and foldable table systems. Each product is designed around the principles of intelligence, silence, and user-centric functionality, blending technology with aesthetics.

This design philosophy is reflected not only in technical specifications but also in the subtle details of user experience: soft seats that contour to the body, headrests that adjust intelligently for optimal support, drawers that glide open silently, and suspended HD screens that illuminate smoothly to deliver striking visuals. These innovations enhance OEM vehicle performance and brand value while creating a refined, tranquil environment for every journey.

To ensure ideal acoustic performance in real-world applications, Southco has established dedicated soundproof testing facilities and leverages the globally recognised ArtemiS SUITE platform for comprehensive sound and vibration analysis. Products are evaluated across different frequency ranges to uncover acoustic behaviours in detail.

Southco's comprehensive testing process is fully customer-oriented and highly customisable, covering data collection methods, measurement distances, evaluation parameters, and reporting formats. Southco engineers have undergone rigorous training with HEAD acoustics, a global leader in acoustic solutions, ensuring every test is precise, standardized, and reliable. By maintaining strict human-machine separation during testing, we minimize interference and guarantee pure results.

Reports go beyond simple decibel readings and reveal how sounds originate and dissipate - helping customers identify potential noise sources, optimise structural design, accelerate product iterations, and ensure every electronic actuation component operates in near silence.

Faster response, deeper insight

Compared to traditional third-party labs, Southco's anechoic testing services offer clear advantages - faster turnaround, smoother communication, and better cost control. Customers avoid long scheduling delays and paying extra fees. More importantly, Southco does not just test, it understands product structures and application scenarios, allowing it to provide targeted improvement suggestions during the design phase.

Southco's services have earned strong recognition across the industry. Southco has helped many leading domestic EV brands optimise acoustic performance and enhance overall vehicle quality. With efficient delivery and rigorous testing, Southco has built a reputation for excellence, and customers consistently value its dual expertise in product development and testing.

Southco's commitment to anechoic testing extends beyond advanced equipment and standardised processes and includes ongoing technology development and team building. Through cross-functional collaboration, Southco has created engineering teams with deep acoustic analysis capabilities, delivering robust technical support to customers. This integrated "design + testing" approach helps brands achieve superior acoustic performance in a competitive market.

Every test is an opportunity to listen to the details and safeguard quality through technology. As EVs enter a new era of quality-driven competition, acoustic refinement moves from being optional to becoming a core factor for brand value.

Southco will continue to advance anechoic testing capability, delivering precise data and expert insights to help industry partners "listen" to the future: creating truly premium, quiet experiences and preserving the beauty of electric mobility.
