Acoustic signals in air and water generated by very shallow marine seismic sources: An experimental study
(Peer reviewed; Journal article, 2020)When a marine seismic source, like an airgun, is fired close to the water surface the oscillating bubble interacts with the water–air interface. The main interest for seismic applications is how this effect impacts the ... -
Acoustically induced cavity cloud generated by air-gun arrays—Comparing video recordings and acoustic data to modeling
(Journal article; Peer reviewed, 2018)For seismic air-gun arrays, ghost cavitation is assumed to be one of the main mechanisms for high-frequency signal generation. Ghost cavitation signals are weak for seismic frequencies (<300 Hz) and do not contribute to ... -
Developing experimental skills: A hands-on course in acoustical measurement techniques at the Norwegian University of Science and Technology
(Peer reviewed; Journal article, 2022)The course “Acoustical Measurement Techniques TTT4250,” offered by the Acoustics Group at the Department of Electronic Systems, Norwegian University of Science and Technology, is a fourth-year course in the specialization ... -
Machine-learning-based estimation and rendering of scattering in virtual reality
(Journal article; Peer reviewed, 2019)In this work, a technique to render the acoustic effect of scattering from finite objects in virtual reality is proposed, which aims to provide a perceptually plausible response for the listener, rather than a physically ... -
Modeling sound scattering using a combination of the edge source integral equation and the boundary element method
(Journal article; Peer reviewed, 2018)A hybrid method for sound scattering calculations is presented in this paper. The boundary element method (BEM) is combined with a recently developed edge source integral equation (ESIE) [J. Acoust. Soc. Am. 133, 3681–3691 ... -
Physics-based characterization of soft marine sediments using vector sensors
(Peer reviewed; Journal article, 2021)In a 2007 experiment conducted in the northern North Sea, observations of a low-frequency seismo-acoustic wave field with a linear horizontal array of vector sensors located on the seafloor revealed a strong, narrow peak ... -
Sound absorption estimation of finite porous samples with deep residual learninga)
(Peer reviewed; Journal article, 2023)This work proposes a method to predict the sound absorption coefficient of finite porous absorbers using a residual neural network and a single-layer microphone array. The goal is to mitigate the discrepancies between ... -
Sound emergence as a predictor of short-term annoyance from wind turbine noise
(Journal article; Peer reviewed, 2023)While sound emergence is used in several countries to regulate wind energy development, there is no published evidence that it is a relevant noise descriptor for this purpose. In the present work, we carried out two listening ...
