dBSea Underwater Noise Course at GMIT, April 2016
We had the privilege of running this course with attendees from France, Denmark, United Kingdom, Greece and Ireland. We trust that the participants learned something from the event, but I must say that we learned much as well. It is amazing to have this amount of experience in one place to discuss the issues of the new and evolving field that underwater acoustics is.
|Some of the common anthropogenic noise sources in the sea.|
|Martin points to a very important point on the results colour grid.|
|Some steps in understanding the way the parabolic equation solver works in dBSea.|
|Pictures from the RENA salvage operation in NZ. Noise modelling was involved in minimising ecosystem damage during salvage activities.|
|The sound life of fish (toadfish singing).|
|"Ducting" can cause sound to travel very strangely in water (see more).|
|Sample spectra of anthropogenic noise sources compared to the frequency specific attenuation profile. Notice how attenuation steeply increases over 10 kHz (>1 dB/km).|
We hope to undertake more of these courses in the future, as we ourselves also benefit hugely from sharing some of our specialised knowledge with the industry, the universities, NGOs and government institutions.
Thanks for joining us for the course and thank for reading.
