The document describes Seven Bel's sound imaging technology, which provides fast and efficient acoustic imaging results in under three minutes. The system is portable, requiring only a mobile device and cloud infrastructure, eliminating the need for additional equipment like notebooks or power supplies.
Key Features
- Speed and Efficiency: Acoustic images are generated quickly, allowing for immediate analysis.
- Portability: The system is ultra-compact and lightweight, enabling use in various locations without dependency on additional hardware.
- Image Quality: Utilizes distributed microphones with advanced semiconductor technology to produce high-quality acoustic images.
- Ease of Use: Simplified workflow for measuring and analyzing sound events, with options to share results via automatically generated reports.
Applications
- Room Acoustics: Identifies sound sources and transmission paths to address acoustic issues in buildings.
- Environmental Noise: Helps in locating noise emissions from industrial facilities to ensure compliance with legal limits.
- Ventilation Systems: Detects airflow noise and weak spots in ventilation systems to prevent noise transmission.
- Building Technology: Assists in locating leakages and weak spots in structural elements like doors and windows.
Specifications
- Sensors: Three models (P50, P132, P254) with varying specifications such as diameter of scan area, weight, rotation frequency, and frequency range.
- Microphone: Features include a sample frequency of 21.5 kHz, 24-bit resolution, and a frequency range of 50 Hz to 20 kHz.
- Environmental Conditions: Operates in temperatures from -10°C to 60°C and relative humidity of 45% to 85%.
- Mobile Device Compatibility: Requires Android OS version 10.0 or higher.
- Analysis Capabilities: Real-time display of time signal, frequency spectrum, and spectrogram, with options for audio playback and automated report generation.
