A noise and track monitoring system consists of several components which collect and store input data, calculate relevant values and prepare them for presentation.Topsonic systems measure continuously and without interruption — 365 days per year, in ice and snow, in the desert and in tropical environments.Noise Monitoring StationThe number of noise monitoring stations depends on the number of runways and certain geographical terms. For each runway at least one station should be located in each extension of the runway.A noise monitoring station mainly consists of measurement instrumentation (sound level meter and weather proof microphone), computer and communication module (router or modem), an optional weather sensor, an uninterruptable power supply (UPS), sensors for vandalism protection, power loss and temperature, a weather proof cabinet and a tilting mast.Topsonic Noise Monitoring Stations operate under the most difficult ambient conditions. The temperature range is -20°C to +55°C. Power consumption is very low. Optional sensors like ADSB receiver or weather proof camera can be integrated.Topsonic noise monitoring stations are protected against lightning and electrical surges.In addition we offer mobile noise monitoring stations for changing sites of operation. Their functionality and measurement instrumentation is identical to our stationary devices. Mobile stations are located either in a handy pelican case or in a car trailer for unattended use. The car trailer version is available with solar power and/or fuel cell power. This allows more than half a year of unattended operation without any external power source.
