Abstract
PURPOSE:To efficiently damp the sound energy by once contracting a sound flux at the inlet part of a reflection chamber formed in the shape of ellipse, and collecting the sound waves reflected on the internal surface of the reflection chamber in a sound-absorbing board arranged at one sound-focusing position of the ellipse. CONSTITUTION:An expansion chamber 6 and a reflection chamber 7 are respectively connected to an inlet pipe 1 in sequence, these chambers are surrounded by an external wall 4, and a face of the external wall 4 touching the reflection chamber 7 is formed in the shape of ellipse. And, an inlet part 8 of the reflection chamber 7 is arranged at one focusing position of the external wall 4 formed in the shape of ellipse, a cylindrical sound-absorbing board 3 being arranged at the other focusing position of the external wall 4 formed in the shape of ellipse. Thus, because the sound flux is once contracted at the inlet part 8 of the reflection chamber 7, and the sound waves reflected on the internal surface of the reflection chamber 7 are connected in the sound-absorbing board 3, the sound energy can be efficiently damped, and the muffling effect can be also improved.
