Abstract
The Kolmården wild life park located in Sweden, asked for adevice to be used in their dolphinarium to enable the trainers to call individual dolphins. This is to be don eusing their signature whistle, which is unique for every animal. Since dolphins themselves are using their signature whistle to make contactbetween eachother, thehypothesis is that teaching them to understand thattheir own unique signature whistle is are call signal, will be easier than with an arbitrary sound. In the current situation knocking the metal fishbuckets on the pool side or a sharp hand splash in the water surface are used as recall, but it will call the whole group.

The Kolmården wild life park located in Sweden, asked for adevice to be used in their dolphinarium to enable the trainers to call individual dolphins. This is to be don eusing their signature whistle, which is unique for every animal. Since dolphins themselves are using their signature whistle to make contactbetween eachother, thehypothesis is that teaching them to understand thattheir own unique signature whistle is are call signal, will be easier than with an arbitrary sound. In the current situation knocking the metal fishbuckets on the pool side or a sharp hand splash in the water surface are used as recall, but it will call the whole group. The idea is that the trainer selects which animal he/she wants to work with and plays the corresponding signature whistle in the water. The whole device or only the transducer will be submerged into the pool, aspherical hydrophone will act as a transmitter to spread out the whistle sound evenly. The aim with this master thesis was to build and test adevice that is capable to transmit the relative low frequency signature whistle, 5kHz-20kHz. The prototype used an Arduino Nano, a microcontroller as a platform. At the end of the project, the prototype was tested in Kolmården. The prototype worked fine to the extent that the signature whistles were properly transmitted in to the waters, and the dolphins could clearly hear them. However, the whistles had no recall effect this has to be taught to the dolphins, as anticipated. All in all the project was successful and there is great potential to further develop the device, e.g, to incorporate not only signatur ewhistles, but also other sounds that can be used to communicate with the dolphins (Less)
