Dolphin-inspired compact sonar for enhanced underwater acoustic imaging
A team of scientists from the National University of Singapore Tropical Marine Science Institute has developed a dolphin-inspired compact sonar with a novel echo processing method that allows for clearer visual imaging underwater compared to the conventional signal processing method of visualising sound echoes.
UW researchers bring first underwater messaging app to smartphones
Researchers at the University of Washington have developed AquaApp, the first mobile app for acoustic-based communication and networking underwater that can be used with existing devices such as smartphones and smartwatches.
DeepSqueak Tool Identifies Marine Mammal Calls #ASA182
As the size and number of acoustic datasets increase, accurately and quickly matching the bioacoustics signals to their corresponding sources becomes more challenging and important. This is especially difficult in noisy, natural acoustic environments. At the 182nd ASA Meeting, Elizabeth Ferguson, from Ocean Science Analytics, will describe how DeepSqueak, a deep learning tool, can classify underwater acoustic signals. It uses deep neural network image recognition and classification methods to determine the important features within spectrograms, then match those features to specific sources.
