RTSYS - Model SYLENCE-LP -1-Input Underwater Acoustic Recorder
SYLENCE-LP underwater acoustic recorders allow cost-effective and reliable acoustic monitoring with best value for money on the market (256 kHz max bandwidth; dynamic range of over 100 dB). 2 models are available: one 22-cm-high version (one fixed hydrophone, 35 days of non-stop recording) and one 44-cm-high version (one fixed or cabled hydrophone, up to 180 days of non-stop recording).
Maritime
90% of global goods are carried by maritime freight and the volumes transported are constantly growing as new routes appear. Consequently ships and cargos need to be increasingly efficient in terms of speed, size and energy consumption. Radiated noise generated by ships must also meet rules and regulations as awareness of anthropogenic noise heightens.
Based on this knowledge, we help shipyards design better ships using Passive Acoustic Monitoring (PAM) either with real-time or post-processing methods. Meanwhile, ships in operation can use underwater acoustics to detect any defects or mechanical failures.
Research & Oceanography
Due to the rise of anthropogenic noise, marine biologists and PAM operators need to keep a constant watch, as underwater sound may affect marine species’ habitats.
Additionally, Protected Species Observers (PSO) and Marine Mammal Observers (MMO) are increasingly learning the importance of underwater acoustics in their understanding of marine wildlife. Species that science thought were soundless until a few years ago appear to express numerous acoustic signals that tell more than the eyes can see.
In addition to biological and anthropogenic sounds, geological sounds (earthquakes, thermal sources …) can be observed helping for a better understanding of oceans.
As the main bulwark against global warming, their chemicophysical properties need to be closely monitored, which can be easily implemented using AUVs, equipped with various payloads for long autonomous surveys.
