An internist, also called a general internist or doctor of internal medicine, is a medical doctor that specializes in the diagnosis and medical (nonsurgical) treatment of adults.
Exhaust resonators, meanwhile, further reduce the noise by making sound waves that cancel noises out. Structure A typical automotive exhaust resonator is made of a hollow steel cylindrical tube and is attached to the muffler of an exhaust system. This type of resonator is designed similar to that of an acoustic resonator, which creates an âexhaust noteâ that gives the exhaust noise a less annoying and more pleasant tone.
Best Answer: The resonator on a car is a hollow chamber in the exhaust tract. Its location is placed a certain distance from the muffler and engine to allow the resonant effect. This is to dampen parts of the noise coming from the engine and enhance other parts of it. Factory car makers tune the location of this resonator to tune the sound of your exhaust to better match the nature of your car ie sporty(loud) vs luxury(quiet) exhaust.
