DESIGN OF A TUNED RESONATOR TO ATTENUATE LOW FREQUENCY SOUND

摘要

Control of noise in the 3 1 .S Hz and 63 Hz octave bands is becoming an increasingly importantissue in the acoustic acceptability of compressor stations. This paper will present a case studydescribing the development of a class of tuned dissipative silencers, or resonators, designed toattenuate such low frequency sounds.
