The Daytona angle round head is made of T-304 stainless steel material, TIG welded, with a limited lifespan guarantee, while the frequency range of the muffler refers to the frequency or frequency range where the damping volume is significant. The frequency characteristics of a muffler are generally in the octave band and one-third octave band. There is no unified quantitative evaluation index for this. Generally speaking, the wider the effective frequency band range of noise reduction, the better. The human sensitive frequency range should have sufficient noise reduction, and the frequency range with high radiated noise at the sound source should have a larger noise reduction. In this way, the application of mufflers for noise reduction will have a better effect.
