It acquires data from 2 wide-band hydrophones and simultaneously sends and displays real-time noise information such as SEL, SPL and 3rd octave band levels within a 10 km range.

This is a robust buoy particularly suited to offshore conditions that is an excellent solution for autonomous real-time noise surveying of harbor construction, pile-driving operations and seismic surveys. With less than 350 kg, it is easily deployed and recovered from a working boat. Rugged buoy RUBHY can be deployed for real-time studies (up to 40 days of non-stop recording) in rough seas (up to sea-state 5). Many options are available and additional sensors can be added.
