Sherbrooke, Quebec - TPV window extrusion company Jyco has said it intends to do more research into acoustic performance of window and door seals. Jyco said it is exploring collaborative efforts with the University of Sherbrooke, located near Jyco's main North America plant in Quebec. Plans include developing an insertion loss chamber to correlate numerical acoustics methods such as FEA, BEM, or SEA to transmission loss and insertion loss test data across seal sections. This could also be used to study and compare noise propagation in various designs, and to determine optimum sealing patch width and configurations for each body seal and glass run channel program.
The company said it is also expanding acoustic testing capabilities at Jyco's Dexter, Michigan engineering centre.
Recent acoustic testing of door seals by Kolano and Saha Engineers compared EPDM sponge parts to geometrical equivalents of extruded JyFlex. They recorded similar results up to 900 Hz, but at higher levels, the JyFlex part significantly improved acoustic performance against wind rush and road noise, said Jyco.
