Soundian

Soundian acoustic imaging is a professional-grade acoustic imaging application independently developed by Shanghai Qigao Electronics Technology Co., Ltd., requiring its high-performance USB microphone array hardware. The application transforms invisible sound into intuitive thermal images, widely used in scenarios such as power line inspection, industrial equipment diagnostics, gas leak detection, and mechanical noise analysis, helping engineers quickly locate sound sources and identify potential faults.

【Company Introduction】

Shanghai Qigao Technology Co., Ltd. focuses on acoustic testing and industrial non-destructive testing, committed to providing customers with high-performance, easy-to-use acoustic imaging solutions. Soundian is its core product line brand.

【Core Functions】

• Real-time Acoustic Imaging
Displays the spatial distribution of sound in real-time using a thermal map overlay method, supporting multiple visualization modes including single sound source, multi-source, and energy distribution. The frame rate is stable and smooth, providing a WYSIWYG experience.

• Professional Spectrum Analysis
Built-in PRPD (Phase-Resolved Partial Discharge) scatter plot and SPL (Sound Pressure Level) trend plot, supporting UHF/HF band switching to facilitate accurate detection of partial discharge in power equipment.

• Transient Signal Capture

Supports single/multiple transient freeze-frame modes, automatically capturing pulse signals and preserving waveform details for easy post-event review and in-depth analysis.

• Video Recording and Playback

Built-in screen recording function (including simultaneous recording of heatmaps and charts), supporting playback, screenshots, and sharing for convenient on-site recording, report generation, and team collaboration.

• Intelligent Parameter Configuration

Supports customizable parameters such as frequency range, dynamic range, imaging speed, and sensitivity; intelligent mode can adapt to typical scenarios with one click, lowering the learning curve.

• Multi-Language Adaptation

Built-in 12 languages: Simplified Chinese, Traditional Chinese, English, Japanese, Korean, French, German, Spanish, Portuguese, Russian, Arabic, and Turkish, with automatic font adaptation.

• Data Management

Built-in photo browsing, playback list, recycle bin, and data query for easy organization of historical records.

【Application Scenarios】

✓ Power Industry: Partial discharge detection of GIS, transformers, switchgear, and cable terminals

✓ Industrial Manufacturing: Compressed air/steam/vacuum leak detection

✓ Equipment Maintenance: Diagnosis of abnormal noises from bearings, valves, compressors, and motors

✓ Building Inspection: Door and window sealing and sound insulation testing

✓ Transportation Maintenance: Insulation testing of electrical cabinets in high-speed rail/subway systems

【Instructions for Use】

This application requires the Soundian acoustic imaging hardware from Shanghai Qigao Electronics Technology Co., Ltd. After connecting the device via USB OTG, the application will automatically recognize it and begin data acquisition. Recommended for use on Android 7.0 and above.
