Measuring acoustic habitats

Measuring acoustic habitats

1. Many organisms depend on sound for communication, predator/prey detection and navigation. The acoustic environment can therefore play an important role in ecosystem dynamics and evolution. A growing number of studies are documenting acoustic habitats and their influences on animal development, behaviour, physiology and spatial ecology, which has led to increasing demand for passive acoustic ...

Measuring Slugging Bed Dynamics with Acoustic Sensors

We describe experimental observations of slugging bed dynamics with passive acoustic sensors. Our results indicate that acoustic signals contain both similar and complementary information relative to dynamic pressure signals. We find that selective preprocessing of acoustic signals is a key step in separating information about microscale and macroscale processes. With such preprocessing, both l...

An Acoustic Sensor for Measuring Traffic Variables

The Intelligent Vehicle-Highway System (IVHS) program requires a large number of sensors to accurately measure traffic data. A novel passive acoustic sensing scheme based upon a triple-aperture microphone array is proposed as an inexpensive, reliable alternative to other sensors under consideration. A single sensor exhibits the potential for monitoring several lanes of traffic simultaneously. A...

Measuring Norwegian dialect distances using acoustic features

Computational dialectometry has been proven to be useful for finding dialect relationships and identifying dialect areas. The first to develop a method of measuring dialect distances was Jean Séguy, assisted and inspired by Henri Guiter (Chambers and Trudgill, 1998). Strongly related to the methodology of Séguy is the work of Goebl, although the basis of Goebl’s work was developed mainly in dep...
