Excess attenuation for sound propagation over an urban canyon
Chalmers Publication Library (CPL) offers the possibility of retrieving research publications produced at Chalmers University of Technology. It covers all types of publications: articles, dissertations, licentiate theses, masters theses, conference papers, reports etc. Since 2006 it is the official tool for Chalmers official publication statistics. To ensure that Chalmers research results are d...
متن کاملSound propagation over soft ground without and with crops and potential for surface transport noise attenuation.
Growing demand on transportation, road, and railway networks has resulted in increased levels of annoyance from road traffic. Optimized use of green surfaces in combination with vegetation may be desirable as a method for reducing the noise impact of road traffic in urban and rural environments. Sound propagation over soft ground and through crops has been studied through outdoor measurements a...
متن کاملAttention Wins over Sensory Attenuation in a Sound Detection Task
'Sensory attenuation', i.e., reduced neural responses to self-induced compared to externally generated stimuli, is a well-established phenomenon. However, very few studies directly compared sensory attenuation with attention effect, which leads to increased neural responses. In this study, we brought sensory attenuation and attention together in a behavioural auditory detection task, where both...
متن کاملSound propagation in interconnected urban streets: a parametric study
A radiosity model has been developed for calculating the sound distribution in urban streets with diffusely reflecting boundaries. In this paper I present the results of a parametric study by using the computer model. A typical urban element consisting of a major street and two side streets is analysed. The analysis is focused on the characteristics of sound pressure level and reverberation tim...
متن کاملSound propagation at micro-scale in urban areas
Whilst large scale noise-mapping techniques have been applied extensively in practice, as required by the EU Directive on environmental noise, they are often not applicable for microscale urban areas such as a street or a square. This talk will discuss a series of simulation techniques as well as related acoustic theories for accurately calculating the sound field for micro-scale urban areas. T...
