All-Weather Windscreen WS-13
WS-13 has bird spikes to keep birds away. Sound Discrimination Unit AN-37
The AN-37 allows discrimination between factory noise and peripheral noise from outside the site, and displays sound source direction. This is used in case of measurement of only the target factory noise. |
Environmental noise measurement system (example)
Great for environmental noise measurements along highways
For Aircraft Noise Measurement
Designed for Long-term Aircraft Noise Monitoring Application. Provides Functionality, Durability and Easy Maintenance Required for Automated System.
The system has a feature for reliable identification of aircraft noise, while its compact dimensions make it suitable also for mobile use. Measurement is fully automatic, and continuous 365-day all-weather operation is supported |
For Aircraft Noise and Ground Noise Measurement
Visualization of how noise sources are identified
Use up to five window areas to distinguish aircraft noise and ground noise from other noise (noise to be excluded).
Single noise event: This is a temporary noise which occurs sporadically, such as noise caused by air travel that can be observed within the vicinity of the airport. Above-ground noise produced by aircraft is also a form of single noise. Long term noise event: This noise is steadily produced over a long period of time, but the noise level fluctuates greatly. Common examples are engine testing noise and the noise originating from the auxiliary power unit (APU). |
