Noise and Vibration in Environment
- distinguish sound and vibration indicators based on sound pressure, intensity and power levels and vibration levels
- explain the origin of mechanical vibrations and basic principles of their abatement
- calculate measures for indoor and outdoor noise protection
- operate instruments for measuring noise and vibration levels
- use noise maps and other indicators for estimating imission levels and evaluating soundscapes
- apply noise and vibration protection laws and regulations for determining their influence on people
Forms of Teaching
