Design and analysis of compact, lightweight material concepts for sound mitigation in flow ducts. KU Leuven
In applications such as automotive exhaust and HVAC systems, a flow duct is the main transmission path for the noise generated upstream. The increasing legal regulations and customer expectations regarding noise emission call for efficient noise control measures in such systems. However, the conventional solutions require a large volume (and subsequent weight) to be effective at low frequencies, conflicting with the trend towards lightweight ...
