Topsonic offers complete solutions for monitoring, recording and analyzing noise. These systems reliably measure sounds and noises and attribute them individually to specific origins (e.g. an aircraft, vehicle or any other distinct source). The measurements are taken continuously and thus provide a permanent record of all noise events.
In addition to stationary or mobile monitoring terminals, Topsonic’s product portfolio includes:
  • Aircraft noise and flight track monitoring system
  • Environmental information system
  • Industrial and construction noise monitoring
