Model-combination-based acoustic mapping [PDF]

open access: yes2001 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.01CH37221), 2002
We propose a method for compensating distortions in the speech signal caused by environment changes. The basic method concentrates on additive noise, but can be extended to address also channel and to some extent speaker changes. By combining compensation with adaptation techniques it leads to high error rate reductions for mobile speech applications ...

Noise maps for acoustically sensitive navigation [PDF]

open access: yesSPIE Proceedings, 2004
More and more robotic applications are equipping robots with microphones to improve the sensory information available to them. However, in most applications the auditory task is very low-level, only processing data and providing auditory event information to higher-level navigation routines.

Measuring acoustic habitats [PDF]

open access: yes, 2015
NDM was part-funded by an EPSRC Doctoral Training Award (No. EP/P505399/1). MPJ and PLT were supported by Marine Alliance for Science and Technology Scotland (MASTS) and MPJ by a Marie Curie CIG Award.Many organisms depend on sound for communication ...

Diesel engine fuel injection monitoring using acoustic measurements and independent component analysis [PDF]

open access: yes, 2010
Air-borne acoustic based condition monitoring is a promising technique because of its intrusive nature and the rich information contained within the acoustic signals including all sources.

Numerical Imaging of the Seabed and Acoustic Flares with Topography and Velocity Variance

open access: yesRemote Sensing, 2022
During seabed mapping, anomalous acoustic events in the seawater layer often degrade bathymetric quality. Acoustic-flare-like events that are induced by gas seepage occur accompanied by small seabed depressions known as pockmarks.

Vowel Acoustics in Dysarthria: Mapping to Perception [PDF]

open access: yesJournal of Speech, Language, and Hearing Research, 2014
Purpose The aim of the present report was to explore whether vowel metrics, demonstrated to distinguish dysarthric and healthy speech in a companion article (Lansford & Liss, 2014), are able to predict human perceptual performance.

Acoustic mapping of mixed layer depth [PDF]

open access: yesOcean Science, 2018
The ocean surface mixed layer is a nearly universal feature of the world oceans. Variations in the depth of the mixed layer (MLD) influences the exchange of heat, fresh water (through evaporation), and gases between the atmosphere and the ocean and ...

Passive Acoustic Mapping for vascular permeability assessment

open access: yes, 2021
Despite significant research efforts, cancer remains one of the leading causes of death globally, and relative survival rates have not improved significantly over the past 40 years. Larger therapeutic agents rely on a high degree of vascular permeability

A Spectra-Based Equalization-Generation Combined Framework for Throat Microphone Speech Enhancement

open access: yesIEEE Access, 2018
Non-acoustic sensors are widely used in speech signal processing tasks, and their immunity to the background acoustic noise shows great benefits to traditional speech enhancement.

Quantitative imaging of acoustic reflection and interference [PDF]

open access: yes, 2015
This paper presents a method for time resolved quantitative imaging of acoustic waves. We present the theoretical background, the experimental method and the comparison between experimental and numerical reconstructions of acoustic reflection and ...
