While your automobile’s exhaust system reduces emissions into the neighborhood, it also reduces engine noise. An automobile engine produces a range of sound frequencies and without the muffler, our streets and freeways would sound like a never-ending NASCAR race.
Mufflers have been around since the early cars were built and use a sound frequency theory developed nearly a half century before the automobile was introduced. The theory states that certain sound frequencies can be cancelled out within a specifically-shaped tube or chamber.
Automobile exhaust systems are pretty durable coming off the line, but corrosion, rough roads and road debris can damage or loosen muffler components. This can often lead to a rattling noise coming from the bottom of the car. Debris could also puncture the muffler, allowing engine noise to escape unfiltered. You may not notice a drop in engine performance, but you will notice the extra noise.
Yet, the last symptom of muffler failure is a drop in engine performance. On modern cars, the exhaust sensors can detect and communicate with the engine computer to adapt to minor engine or exhaust fluctuations. But after a point, the performance levels drop beyond the capability of the engine to reciprocate, causing a significant drop in overall engine performance.

Exhaust Mufflers
Noise pollution has long been a source of discontent in large population centers. Ancient civilizations restricted travel after dark because of the distraction of street noise. As United States population centers blossomed, public sentiment over noise pollution from the increasing size of the machines that moved them was building.
Exhaust systems have been around since the early days of the automobile. These early exhaust systems were similar to modern exhaust systems with long steel tubes leading from the exhaust manifold and leading to the rear of the vehicle to the muffler. Back then, exhaust systems were designed more to help dissipate the heat and keep the fumes from the engine and passenger compartment. It did very little about the noise.
This system remained more or less until just after WWII as manufacturers were refining their production processes to increasingly tighter tolerances and with greater knowledge of sound management.
The design of the muffler was based on the sound resonating principle developed by Hermann von Helmholtz in the mid-19th century. Helmholtz proved sound frequencies could be canceled out by a matching frequency within an appropriately sized chamber. For automobile exhaust, that chamber is the muffler. The muffler is designed so the sound reverberates within the muffler chambers, significantly reducing the overall engine noise.
By the 1960’s, pollution became a hot social issue and noise came along for the ride since it was usually generated by an engine producing toxic exhaust. In response, car manufacturers began introducing automobiles with a new device called a resonator. This device works in tandem with the muffler to eliminate increasingly more sound frequencies from the engine. But instead of reducing sound, the resonator’s job is to give the sound a different, more tolerable, frequency.
