- W1007248712 abstract "Duct end reflection loss (ERL) is the apparent loss of sound power resulting from an abrupt change in cross-sectional area of a duct. The literature describes the ERL mainly as a function of frequency and opening size. The American Society of Heating, Refrigeration, and Air-Conditioning Engineers' Applications Handbook describes the sound power loss due to ERL. Engineers normally apply the ERL as an attenuation value in their acoustic system calculations. However, ERL values are based on analytical plane wave assumptions for long and straight duct sections. Many fan and air distribution systems do not have long straight sections before the termination. The impacts due to curved sections, T-ducts and elbow turns on ERL are not known. This paper describes laboratory-measured changes in pink noise levels that result from close-coupled elbows that are commonly found in fan and air distribution systems. The sound level changes, both within the duct and at the termination, may be attributed to the variability in the apparent ERL." @default.
