| 102-0535-00L | Noise Abatement  | 5 credits | 4G | K. Eggenschwiler, J. M. Wunderli | |
| Abstract | Basics of acoustics and hearing. Measurement of sound. Impact of noise (physiological, psychological, social, economic). Legislation (focus on Swiss noise abatement ordinance), spatial planning. Sound propagation outdoor and in buildings. Calculation models and measurement procedures. Traffic noise (roads, railways, airports), shooting noise, noise from industrial plants. Building acoustics. | ||||
| Learning objective | The students will understand the basics of noise abatement: acoustics, impact of noise, meas-urement techniques and legislation. The students will be able to analyze different noise prob-lems and they will be able to solve simple problems of noise abatement. | ||||
