A muffler is provided for use in conjunction with a jet for treating a running length of yarn. Audible noise which is emitted by the jet is reduced by at least 11.5 .DELTA.dB(A) through the use of a housing to substantially enclose the jet. The housing has openings for the entrance and exit of a yarn and is at least partially lined with sound absorbing material; sound absorbing material also closes the openings in the housing. The travelling yarn abrades through the sound absorbing material at the openings to form an operational passage to and from the jet.
