16. Variations in sound insulation in lightweight timber constructions
Sammanfattning : This licentiate thesis deals with the topic of variations and uncertainties in building acoustic parameters for lightweight timber constructions. A higher safety margin to the legal requirements is needed to compensate for acoustical uncertainties, which leads to higher costs. LÄS MER
17. 3D Auditory Displays for Driver Assistance Systems
Sammanfattning : A constantly increasing number of advanced driver assistance systems are implemented in cars.The driver is required to interpret the data reported by these systems while driving, and thereforeit is important to know how the information signals provided by such systems affect the driver.

18. Critical noise factors and their relation to annoyance in working environments
Sammanfattning : Noise is one of the most widespread problems in working environments. Besides the obvious risk of hearing damage and masking of warning signals and speech, the effects on concentration, performance, behaviour and general well-being are serious consequences of annoying noise in the working environment.

19. Methods for motor noise evaluation and control in electric vehicles
Sammanfattning : Complete vehicle, system and component target setting for noise, vibration and harshness (NVH) are important activities within automotive product development. New challenges arise when electric motors are introduced into cars traditionally powered by internal combustion engines (ICE). LÄS MER
20. Room acoustics and cognitive load when listening to speech
Sammanfattning : The present thesis investigated the effects of background noise or a long reverberation time in learning situations. All studies used spoken texts that were presented above the speech intelligibility threshold, but were degraded enough to make listening more effortful. LÄS MER
