Samenvatting

This paper examines the escalating issue of low-frequency noise (LFN) pollution,
which predominantly originates from man-made sources, contributing significantly
to sleep disturbances and other health risks. The focus is on the evolution and
efficacy of various noise reduction technologies, particularly those designed for
fans. Techniques ranging from passive mufflers and geometric blade modifications
to advanced materials are discussed. Additionally, the paper introduces an innovative solution, the Anechoic Broadband Compact (ABC) muffler, specifically designed for the HVAC industry (heating, ventilation and air conditioning), offering
significant potential in mitigating LFN across a broad spectrum of frequencies.
