In this paper, we present an approach to improve the accuracy of environmental sound event detection in a wireless acoustic sensor network for home monitoring. Wireless acoustic sensor nodes can capture sounds in the home and simultaneously deliver them to a sink node for sound event detection. The proposed approach is mainly composed of three modules, including signal estimation, reliable sensor...
Orchard fruits are vulnerable to wild birds and animals. One peck on fruit results in critical damage to the produce. Therefore, it is very important to monitor the nearby presence of birds and animals. Then the actuation of various devices should follow to repel the hazardous animals. Traditional methods have been widely applied depending on the kinds of produce and imperiling animals. In this paper,...
In this paper, in order to improve the entertainment dolphin robotpsilas ability to interact with people, a pair of microphones as the ears of a dolphin robot is used to estimate the peak sound directions from surrounding viewers. Dolphin robots should turn towards people who want to interact with them, while swimming autonomously. A pair of left and right microphones is located to form the binaural...
We present experiment of sound source localization using the microfabricated piezoresistive multi-cantilever microphones and an ITD (interaural time difference) method which finds the sound source by phase delay of two signals. The multi-cantilever microphones are designed and fabricated to separate directly the single tone of frequency signals from the sound source. The resonant frequency of multi-cantilever...
