Sonata Exhaust Silencers or Mufflers as they are commonly known are suitable for noise control of the exhaust gas on two or four stroke engines, rotary and reciprocating engines and vacuum pump intake and discharge lines. Combinations of reactive and absorptive designs provide maximum attenuation at all frequency bands dependent on applications and pressure losses tolerated. Reductions of 40-50dB(A) can be achieved with speciality designs. Sound Control's extensive range of Sonata Silencers (Mufflers) can be custom designed to ensure optimum acoustic performance for every application.
