U ovom radu opisuje se izrada funkcionalnog i ekonomičnog hidrofona za sonarne primjene, koristeći piezoelektrični disk kao osnovni senzor. Rad predstavlja niskobudžetno rješenje za izradu hidrofona, koje ostvaruje pristupačnu cijenu uz zadovoljavajuću funkcionalnost. Analizirana je frekvencijska karakteristika piezodiska, te je konstruirano pojačalo s

2022 IEEE Sensors, 2022 Abstract: In the last decades our never-ending desire for space exploration has grown exponentially. In this endeavour, one of the major points of interest is the red planet Mars. To autonomously navigate the Martian terrains a combination of optical sensors (LiDAR, Camera) are used in the latest NASA Perseverance Rover.

ouvirOUver, 2020 As composições sonoro-visuais de O Grivo possibilitam múltiplas experiências numa relação entre música, instalação e performance. As esculturas sonoras inventadas pelos artistas, a partir de fragmentos, impressionam não só pelas formas, mas também pela presença que assumem no espaço, criando uma territorialidade expansiva que transita entre a gambiarra

The use of active sonar to study cetaceans [PDF]
, 2012 Cetacean species face serious challenges worldwide due to the increasing noise pollution brought to their environment by human activities such as seismic exploration. Regulation of these activities is vaguely defined and uncoordinated.

A risk function for behavioral disruption of Blainville’s beaked whales (Mesoplodon densirostris) from mid-frequency active sonar [PDF]
, 2014 There is increasing concern about the potential effects of noise pollution on marine life in the world’s oceans. For marine mammals, anthropogenic sounds may cause behavioral disruption, and this can be quantified using a risk function that relates sound
