UPDATE: Soundtrap has now changed name (due to a conflict of names) to Open Acoustic Devices. The detector we're using is now called the AudioMoth. For this blog post we'll keep the references as 'Soundtrap' as it was at the time.
Here's the original post:
A short time ago we were contacted by a small group of academics who have designed and produced a small ultrasound detector. The detector is called a Soundtrap and their detector is designed as a low-cost open-source acoustic logger for biodiversity and environmental monitoring. For more information on Soundtrap, please visit their website: http://soundtrap.io/
The group is made up of researchers at the University of Oxford and University of Southampton and they have been kind enough to send us one of their detectors to do some testing with. The detector has already been deployed for a number of experiments around the world and if you're interested in it then we'd highly recommend checking out their website.
One of the major benefits of this detector is the size - it's tiny! This is a big help as the less weight we carry when flying the better; although, when using a detector on the boat this is less important. Have a look at the photo below to see just how small it is next to a normal size business card:
During our weekend testing of the new plane (the Talon, see the blog post here) we were actually able to do some side-by-side comparison testing with the Soundtrap and the Peersonic and we'll be putting up another post about this shortly.
Our plan at the moment is to run both the Soundtrap and the Peersonic concurrently to give us the best chance of capturing some good data.
We'd also like to take this opportunity to say thank you to Alex, Peter and Andrew at Soundtrap who have been fantastic!
