We have been developing aircraft noise monitoring systems which consist of a data logger, aircraft noise discriminator and software, from the viewpoint of users who work in the actual fields, in addition to that, our system is at the same time reliable and cost-effective.
Aircraft Noise Monitoring Device
We have devised a DL series aircraft noise monitoring devices through our experience, technology, knowledge about measurement equipment, hardware and software used in the area of field measurement. We can offer both a permanent monitoring station and a portable monitoring station to fulfill the needs from our clients to monitor their field conditions.
Aircraft Noise Discriminator Type-I
The aircraft noise discriminator type-I observes radio wave of a transponder and judges whether the target noise is an aircraft noise or not by distinguishing the correlation between the noise level and the radio wave's intensity level.
Aircraft Noise Discriminator Type-II
By receiving the terrain clearance measuring radio, Aircraft noise discriminator type-II can measure the accurate point-blank passing time and can detect the direction of the aircraft.
Actual Sound Recorder
The actual sound recorder can capture the sound waves of noise by recording the data to a hard disk. Combined with the Aircraft noise discriminator, the aircraft noise monitoring station in the field can record the actual sound of noise events and then transmit them to a central data collection location, after that, the operator can listen and verify the noise event.
Aircraft Noise Source Discriminator
Even in conditions where there are a variety of noises, by separating each of the multiple noise sources which are contributors to the sound pressure level, the aircraft noise source discriminating system can judge whether the dominant noise source is an aircraft noise or not.
Takeoff/Landing Time and Using Runway of Aircrafts Measurement System
By observing the radio waves of an aircraft, monitoring the aircraftfs precise takeoff/landing time and the usage of the runway is possible. Using this technology, this system can identify a noise event, which was observed at a monitoring point at an airport and runway. This system can easily analyze and summarize the aircraftfs noise data in respect to each airport and runway.
Flight Path Monitoring System
By measuring from which direction an aircraft noise is coming from, this system can calculate the continuous 3-D flight paths.
Aircraft Noise Data Processing System
This system collects data from a permanent monitoring station, portable monitoring station, or a flight path monitoring station, and then it will analyze and calculate those data and generate various kinds of reports or database.
