Sound due to an impulsive line source

Non-Line-of-Sight Localisation of a Sound Source

Detection and Recognition of Impulsive Sound Signals Detection and Recognition of Impulsive Sound Signals

This thesis is dedicated to the development of automatic methods for detecting and recognizing wideband impulsive sounds. An extensive database with more than 1000 sound samples has been built. This database is made of 10 diversified sound classes connected with surveillance and security applications: door slams, glass breaks, human screams, explosions, gunshots, dogs barking, low bangs, phone ...

Localisation of an Impulsive Acoustic Source in an Urban Environment

This paper concerns the inverse problem of localising an impulsive acoustic source in an urban environment using measurements from multiple receivers (microphones) distributed through the propagation domain. In free space the inverse problem is readily solved by Time Difference Of Arrival (TDOA) localisation. In urban environments there may not be a lineof-sight (LOS) between the source and eac...

Solvability of an impulsive boundary value problem on the half-line via critical point theory

In this paper, an impulsive boundary value problem on the half-line is considered and existence of solutions is proved using Minimization Principal and Mountain Pass Theorem.

Sound transmission of cavity walls due to structure borne transmission via point and line connections.

The author has published equations for predicting the air borne sound transmission of double leaf cavity walls due to the structure borne sound transmission across the air cavity via (possibly resilient) line connections, but has never published the full derivation of these equations. The author also derived equations for the case when the connections are rigid point connections but has never u...
