Sound signals have been widely applied in various fields. One of the popular applications is
sound localization, where the location and direction of a sound source are determined by …

A method of detecting and counting road vehicles using an acoustic sensor placed by the
road is presented. The sensor measures sound intensity in two directions: parallel and …

The performance of a time difference of arrival (TDOA) localization system is severely
affected by time synchronization errors, and making use of reference signals is a common …

This letter presents a comparison of acoustic particle velocity sensor versus conventional
microphone in terms of a time-domain resolution. To the best of the authors' knowledge, this …

This article proposes an original approach aimed at modelling the noise density in sensors
based on a single hot wire or pairs of thermally coupled wires. The model consists in an …

Acoustical particle velocity sensors for applications in the ultrasonic frequency range are
investigated by means of finite element simulations. The operating principle of these devices …

A 2-dimensional acoustic sensor with programmable directivity is proposed. The sensor is
formed by the combination of two orthogonal detectors of acoustic particle velocity …
