An investigation of the relationship between texture and tyre/road noise for different types of road surfaces and passenger car tyres
Berge, Truls Svenn; Viggen, Erlend Magnus (Chapter, 2014)The texture of the road surface has a major influence on the generation of tyre/road noise. For dense surfaces this may be the most important factor besides the tyre characteristics themselves. Throughout several projects, ... -
Analysis of outer-casing echoes in simulations of ultrasonic pulse-echo through-tubing logging
Viggen, Erlend Magnus; Johansen, Tonni Franke; Merciu, Ioan Alexandru (Journal article, 2016)Cased petroleum wells must be logged to determine the bonding and hydraulic isolation properties of the cement. Ultrasonic logging of single casings has been widely studied and is commercially available. However, ultrasonic ... -
Development of an outdoor auralisation prototype with 3D sound reproduction
Viggen, Erlend Magnus; Vennerød, Jakob; solvang, Audun; Olsen, Herold (Journal article, 2015)Auralisation of outdoor sound has a strong potential for demonstrating the impact of different community noise scenarios. We describe here the development of an auralisation tool for outdoor noise such as traffic or industry. ... -
Simulation and inversion of ultrasonic pitch-catch through-tubing well logging with an array of receivers
Viggen, Erlend Magnus; Johansen, Tonni Franke; Merciu, Ioan Alexandru (Journal article; Peer reviewed, 2016)Current methods for ultrasonic pitch-catch well logging use two receivers to log the bonded material outside a single casing. For two casings separated by a fluid, we find by simulation that increasing the number of receivers ... -
Simulation and modeling of ultrasonic pitch-catch through-tubing logging
Viggen, Erlend Magnus; Johansen, Tonni Franke; Merciu, Ioan Alexandru (Journal article, 2016)Cased petroleum wells must be logged to determine the bonding and hydraulic isolation properties of the sealing material and to determine the structural integrity status. Although ultrasonic pitch-catch logging in single-casing ... -
Speech Enhancement with Deep Learning
Gelderblom, Femke B.; Viggen, Erlend Magnus (Conference object, 2017) -
Subjective evaluation of a noise-reduced training target for deep neural network-based speech enhancement
Gelderblom, Femke B.; Tronstad, Tron Vedul; Viggen, Erlend Magnus (Journal article; Peer reviewed, 2018)Speech enhancement systems aim to improve the quality and intelligibility of noisy speech. In this study, we compare two speech enhancement systems based on deep neural networks. The speech intelligibility and quality of ... -
Subjective Intelligibility of Deep Neural Network-Based Speech Enhancement
Gelderblom, Femke B.; Tronstad, Tron Vedul; Viggen, Erlend Magnus (Journal article; Peer reviewed, 2017)Recent literature indicates increasing interest in deep neural networks for use in speech enhancement systems. Currently, these systems are mostly evaluated through objective measures of speech quality and/or intelligibility. ... -
