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

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
Faint Abnormal-Sound Detection for Motors, Automotive Electronics and Mechanical Structures

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.
