Acoustic Engineering 标准制定级声学品质
Eliminate Ambient Noise and Restore True Product Sound
Solve low-frequency structure-borne noise and background fluctuations with an industrial-grade quiet space for electroacoustic components, smart audio and automotive abnormal-sound inspection.
Built for Demanding Standards-Based Test Applications
Electroacoustic and Audio Certification Test Environment
Blocks surrounding workshop noise and creates a clean acoustic environment for frequency-response and distortion testing of components and finished products。
- Acoustic calibration for smartphone speakers and miniature microphones (MIC)
- Batch acoustic performance testing for TWS Bluetooth and ANC headphones
- R&D testing and quantitative human-machine voice interaction for smart speakers and in-vehicle audio
Faint Abnormal-Sound Detection for Motors, Automotive Electronics and Mechanical Structures
A high-damping quiet environment, precision acoustic probes and AI algorithms capture faint mechanical friction and buzzer noise on production lines
- Batch inspection of miniature motors, stepper motors and cooling-fan noise
- QA control of buzzer sounds from automotive ECUs and relay operation
- Exclusion analysis of faint operating noise in precision medical instruments
Why Do Conventional Soundproof Boxes Repeatedly Distort Test Results?
Low-end enclosures lack structural damping and sound-absorption design, so small acoustic defects cause batch misjudgments and missed defects.
💠 Low-Frequency Resonance and Missed Noise
Poor panels lack damping isolation; low-frequency vibration from presses and motors passes through directly, increasing false judgments on the production line.
🛡 Internal Reflection and Distorted Frequency Response
Ordinary acoustic foam has uneven absorption, creating standing-wave reflections and severely distorting microphone frequency-response curves.
🏅Seal Degradation and Poor Durability
After tens of thousands of cycles, hinge deformation can cause leakage and reduce noise attenuation from 40 dB to 25 dB.
🎖️Ventilation Noise During Heat Dissipation
Without a dedicated labyrinth airflow path, adding a fan compromises the sealed acoustic environment during long-duration full-load testing.
