A closer look
Combustion engines are fundamentally just contained explosions, meaning they are naturally deafeningly loud. A muffler doesn't merely absorb this horrific racket; it actively uses the chaotic science of destructive interference to kill the noise. The hollow canister is packed with a complex maze of perforated tubes and baffle plates. As the violent exhaust pulses enter, the soundwaves aggressively bounce into one another, canceling out specific aggressive frequencies before they can escape the tailpipe. It's essentially a silencer for your explosive engine.
