Active noise control, Tu4.E.2 | Resumen: | This paper deals with the design and optimization of a hybrid passive/active liner for broadband noise reduction in a standing wave tube. The thickness of the multilayer absorbent is reduced in two steps: firstly a porous layer backed by an air gap is substituted by a microperforated panel followed by a reduced air gap; and secondly, the secondary loudspeaker is replaced by a thin plate driven by a piezoceramic patch. Experimental results show that high absorption may be achieved in a wide frequency range (100-900 Hz) with a thin hybrid passive/active absorber. | Descripción: | Communication presented at the 18th International Congress on Acoustics (ICA 2004): "Acoustical Science and Technology for Quality of Life", Kyoto, 4-9 April 2004. | URI: | http://hdl.handle.net/10261/5994 |
