2.6 and 5.1 Sponsored a Transactions Seminar at the Annual Meeting

Current Research Topics on HVAC Duct Acoustics
Chair: Curt Eichelberger, P.E., Member, Johnson Controls, York, PA

This session presented the results of two research projects, sponsored by TC2.6 on duct acoustics. RP1314 is an experimental investigation of the duct end-reflection loss at low frequencies. RP1219 is an experimental investigation of duct rumble noise in air distribution systems. Results from both of these projects will be helpful to design professionals who are concerned with sound generation and propagation in HVAC ducts.
