Acoustic scattering in an ocean environment

Acoustic Environment in the Bus: an Empirical Study

Traffic snarl-up or traffic jam is a common phenomenon in Puri, one of the imperative pilgrimage sites for Hindus as well as a popular tourist destination in India. Traffic congestion inevitably produces traffic noise, in turn annoying the drivers, leading to road rage. Keeping this in mind, the present article has monitored and assessed different noise descriptors in 7 different types of buses...

On the inverse scattering problem in the acoustic environment

1 In this report, we construct numerical algorithms for the solution of inverse scattering problems in layered acoustic media. Our inverse scattering schemes are based on a collection of so-called trace formulae, and can be viewed as extension of the work started in [3]. The speed c of propagation of sound, the density ρ, and the attenuation γ are the three parameters reconstructed by the algor...

An autonomous system for ocean acoustic tomography

Ocean Acoustic Interferometry Experiment

Ocean acoustic interferometry (OAI) is a technique which relates the cross-correlations from a line of active sources to two receivers within a waveguide, and the time domain Green’s function between said receivers. Within this paper, three specific OAI source geometries are briefly introduced and explained. Experimental OAI data were collected during the SW06 (Shallow Water ’06) sea trials dur...
