摘要:
This paper presents a method for calculating the performance of acoustic circuits containing lined ducts. The diameters of the ducts must be less than one‐half the wave‐length of sound in free air. The cases of long and short ducts are treated. For the latter, equivalent electrical circuits are given, and some discussion is given concerning the equivalent electrical circuits for long ducts. A brief list of formulas applicable to filters employing lined tubes is given.
