For the collection of field data, two cruises were made on Fishery Oceanographic Research Vessel Sagar Sampada, an Indian research vessel that is equipped to carry out multidisciplinary research in oceanography with an objective of monitoring, collection, and characterization of acoustic emanation from target noise sources.
The method requires a noise sensor, and a sufficient noise suppressing effect is not obtained when the target noise cannot be accurately detected.
Instead of the standard [L.sub.2] fidelity term in (2.3), in order to explicitly exploit the assumption that the noise distribution is known, we introduce a novel residual fidelity term that enforces the similarity between the residual distribution and the target noise distribution, thus obtaining the penalty formulation,
Forty people were arrested, cited or warned Friday night and early Saturday as Eugene police continue to target noise and alcohol violations in neighborhoods west and south of the University of Oregon.
"Directional microphones can target noise and keep it in the background." Some aids now disappear into the ear canal, making them invisible and eliminating nuisance feedback.
Because sound exists as compression waves in the air, opposite peaks and dips of compression from the speaker nullify target noise in the cavity between the phone and the ear, Zuniga explains.
