16. Vehicle Disc Brake Roughness Noise : Experimental Study of the Interior Noise andVibro-Acoustic Modelling of Suspension Systems
Sammanfattning : Prediction of vehicle disc brake roughness noise is a non-trivial challenge. In fact, neither the source mechanisms, nor the transfer paths are so far well understood. LÄS MER
17. Prediction and Optimisation of Traffic Noise. A Study on Noise Barriers and Shielded Areas
Sammanfattning : The main contribution of noise levels in cities is today road traffic. The strongest source for all road vehicles is most often the tyre-road contact. This source position close to the ground is fortunate with respect to secondary noise abatement measures, such as absorbing road surfaces or noise barriers. LÄS MER
18. Gear noise and vibration : influence of gear finishing method and gear deviations
Sammanfattning : .... LÄS MER
19. GaN HEMT Low Frequency Noise Characterization for Low Phase Noise Oscillator Design
Sammanfattning : The thesis presents low frequency noise (LFN) characterization of Gallium Nitride (GaN) High Electron Mobility Transistors (HEMTs) for low phase noise oscillator design. First, GaN HEMT technology is benchmarked versus other transistor technologies, e.g. LÄS MER
20. Noise and music : a matter of risk perception
Sammanfattning : The prevalence of tinnitus and hearing impairments among adolescents seems to increase as a consequence of exposure to loud noise. Several studies have highlighted the negative auditory effects of exposure to loud music at concerts and discotheques, environments in which young people today spend considerable periods of time.
