1. Environmental Impact from Wave Energy Converters : Underwater Noise
Abstract : Wave energy conversion is a potentially clean and sustainable form ofenergy conversion with no emissions of gases or liquids during operation.There are other environmental issues that need to be taken in consideration.The deployment of a wave power farm will contribute with new surface formarine organisms to colonize.

2. Human response to wind turbine noise : perception, annoyance and moderating factors
Abstract : Aims: The aims of this thesis were to describe and gain an understanding of how people who live in the vicinity of wind turbines are affected by wind turbine noise, and how individual, situational and visual factors, as well as sound properties, moderate the response.Methods: A cross-sectional study was carried out in a flat, mainly rural area in Sweden, with the objective to estimate the prevalence of noise annoyance and to examine the dose-response relationship between A-weighted sound pressure levels (SPLs) and perception of and annoyance with wind turbine noise.

3. Underwater radiated noise from Point Absorbing Wave Energy Converters : Noise Characteristics and Possible Environmental Effects
Abstract : The conversion of wave energy into electrical energy has the potential to become a clean and sustainable form of renewable energy conversion. However, like all forms of energy conversion it will inevitably have an impact on the marine environment, although not in the form of emissions of hazardous substances (gases, oils or chemicals associated with anticorrosion).

4. Noise and music : a matter of risk perception
Abstract : 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.

5. Study of Supersonic Jet Noise Reduction using LES
Abstract : Increases in air traffic and denser population around airports have led to stricterregulations on aircraft noise. High noise levels from high-speed aircraft can causehearing damage in pilots and the airfield personnel. The engine is the main sourceof noise of all jet aircraft and is therefore a key component for improvement. READ MORE
