	Muffler with Perforates Reflective mufflers are best suited for the low frequency range where only plane waves can propagate in the system, while dissipative mufflers with fibers are efficient in the mid-to-high frequency range. Dissipative mufflers based on...
	Absorptive Muffler The sound level from a car depends to a great extent of the quality of the muffler. Over the years, researchers in the car industry have struggled to produce mufflers that are efficient from both an acoustic and an environmental...
	Car Interior In this model, a point source generates a pressure wave in the Sound Brick, a testbench car interior. The sound level is measured at another point and at a range of frequencies high enough that a good mesh resolution is required to...
