151-0232-00L | Engineering Acoustics Note: The previous course title until FS22 "Engineering Acoustics II" | 4 credits | 3G | N. Noiray, S. M. Schoenwald, B. Van Damme | |||||||||||
Abstract | This course presents several applications of engineering acoustics. It consists of three parts: acoustic wave absorption in fluids and vibration isolation in solids, sound radiation and transmission in structures, and aero- and thermo-acoustic sources and instabilities. | ||||||||||||||
Learning objective | Application of the basic concepts of engineering acoustics: acoustic absorption, solid wave propagation, acoustic transmission and sound radiation by reacting and non-reacting flows in complex engineering systems that are relevant to noise control practice. The lectures (10x3 hours) cover the broad field of modelling, analysis, design and testing of flows, materials and structures with the aim of developing systems which exhibit the targeted acoustical behavior. The theoretical content is supported by 3x3 hours of lab visits, including hands-on experiments and demonstrations of real-life acoustic measurements | ||||||||||||||
Content | Wave Attenuation, Vibration Damping, Acoustic Absorption, Sound Transmission, Radiation, Broadband and Tonal Aeroacoustic Noise, Active and Passive Control of Thermoacoustic Instabilities. | ||||||||||||||
