hi friends....
we are trying our best to design our own muffler this year. can u help us out in some respect. we are lacking in how to decide the density, radius of perforations in absorption muffler. i got report on this but, it is for 6 cylinder engine. i need it for 4 cylinder.
does the attenuation(transmission loss) depends on thickness of absorbing material, how we can decide it (parameters to decide).
length of muffler is an important task............we hav not got any proper information for this.
thanking in aticipation.
