A Study of Radiated Noise From Fishing Vessels
(Master thesis, 2017)The oceans are covering most of the earth. The noise levels in the oceans are high, even though most people are ignorant to the fact. Through the increase in anthropogenic noise in the oceans, the ambient noise level is ... -
Comparing measurements and simulations for acoustics in open-plan office spaces
(Master thesis, 2017)This report is the result of a master thesis at the Norwegian University of Science and Technology (NTNU). The ISO 3382-3 standard describes the measurement procedure of room acoustical parameters in an open-plan office. ... -
Comparison of impulse noise measurements and calculations by noise prediction methods: ISO 9613-2, NMPB-2008, Nord2000 and Harmonoise
(Master thesis, 2017)This master s thesis presents a comparison between impulse noise measurements and calculations from four well-known propagation models; ISO 9613-2, NMPB-2008, Harmonoise and Nord2000. The calculated values are compared to ... -
Forest Attenuation of Noise from Trams and Metros - A case study of the Oslo tramways and metros
(Master thesis, 2018)The influence of vegetation and trees on sound propagation has been investigated by compar- ing measurements of metro and tram noise pass-by in an open field with a forest. The mea- surements are based on the metros and ... -
Implementation of a Relative Positioning System based on Ultrasound
(Master thesis, 2016)Speech communication is essential in human interaction. When working or residing in noisy environments, hearing protectors must be used. This leads to reduced communication abilities. If traditional communications systems ... -
Lydfelt i smale bygater med trikketrafikk - En analyse av målinger og simuleringer av trikkestøy i Storgata i Oslo.
(Master thesis, 2016)Med økende folketall i storbyer øker også behovet for kollektivtilbud. I Oslo består store deler av kollektivtilbudet av trikk, og dette kan føre til støyproblemer i utsatte områder. Med dagens prediksjonsmetoder for ... -
Perception vs. Quantification of Wind Turbine Noise
(Master thesis, 2018)The number of wind farms in the world, and in Norway, is increasing. As a consequence, the issue of noise annoyance and possible negative health effects caused by wind turbine noise, has become more prevalent. There are ... -
Personlig tilpasning av HRTF-sett for 3D-lyd
(Master thesis, 2016)For at vi skal kunne benytte oss av vår binaurale hørsel i virtuelle applikasjoner, ved bruk av hodetelefoner, trenger vi Hode-Relaterte Overføringsfunksjoner, forkortet til HRTF på engelsk. Uheldigvis vil denne HRTF'en ... -
Sound Field on Balconies
(Master thesis, 2017)Environmental noise caused by traffic, industrial and recreational activities is an increasing problem affecting more and more people in their homes, especially in urban areas. Balconies attached to building façades can ...
