Airport & Aircraft Noise Monitoring
Noise level monitoring
The sound level meter monitors airport noise indicators, including LAmax, Td, LAE, LAS, and more. The data is transmitted via wireless or wired networks to data centers for statistical analysis, which facilitates the assessment of airport noise levels.
Optional Configuration: The sound level meter can be used with an outdoor microphone and shield for additional measurement capabilities.
Data recording and analysis：The monitoring data are recorded in detail and statistical analysis is performed to assess the trend and scope of the noise level.
Automatic Flight Event Identification
The device integrates with radar data and flight information, using noise data from monitoring points to automatically and accurately identify flight events.
Pattern Recognition：Using machine learning or deep learning algorithms, the collected data is analyzed to identify and classify flight noise events.
Message Feedback：The identification results can be fed back to airport operations management in real -time for noise management and decision support.
Noise Level Exceedance Identification
The device intelligently recognizes a range of sound sources, including aircraft noise, traffic noise, and natural environmental sounds. When used in conjunction with a sound source tracker, it accurately determines the direction of these sound sources, offering robust data support for addressing resident complaints, collecting evidence, and enforcing regulations.
Accurate measurement：A high-precision sound level meter or other noise monitoring device is used to ensure the accuracy of measurement results.
Data analysis：The collected noise data is analyzed to identify noise patterns, peaks, and durations.
Noise Monitoring: Early Warning Functionality
A sound level meter can issue early warnings for noise complaints or special events, identify the primary causes through noise monitoring data and flight track analysis. It also can recommend targeted noise reduction measures and solutions.
Default threshold：The system sets allowable thresholds for noise levels based on local noise control standards or regulations.
Alarm system：When the noise exceeds the standard, the system will automatically trigger the alarm, notify the relevant personnel, or automatically start the corresponding countermeasures.
