Aircraft Muffler Why are airplanes SO darn loud? Can't they put mufflers on them?
Commercial and military aircraft fly over my house all the time. I can barely see the plane but I can sure hear them. Can't someone make mufflers for them? Why doesn't the EPA noise level section make mandatory sound pollution control requirements for aircraft?
Everyone that suggested that I move, is being unrealistic. Where would a person move to that never has any planes flying overhead? I've lived in 5 USA states and in Mexico and they all have planes.
My question is Can't 20th century technology make a quiet aircraft?
They do make noise level requirements. That is why they fly so far above you. If they flew at lower altitudes, they would be breaking the law. A little over 20 years ago, military craft would fly at super sonic speeds over farmland. Farmers complained about the sonic booms, which I enjoyed. The claims were that chickens quit laying eggs, cows milk was bad or the milk quit flowing, other livestock related complaints. Today, I no longer hear sonic booms. As far as the noise is concerned, that is directly related to energy and power. The more energy associated with a process, the more noise or light or heat produced. The more power used, or energy per unit time, then the more noise. Huge aircraft require incredible amounts of energy. The fuel consumption of a commercial air craft is similar to that of the number of cars required to transport the same number of people over roughly the same distance. How many people can some hold? If you pick one that will hold 150 people, that is roughly equivalent to (150/4) cars or 37 cars. That is a lot of power and fuel consumption over a 750 or 1000 mile trip. That is a lot of noise.

Car manufacturers these days comply with the myths and expectations of mainstream customers who hold the notion that low velocity super-quiet exhaust systems are ideal. Lowering the velocity of the exhaust systems restricts the car and results in under performance. Boosting car exhausts flow velocity will help optimize power and maximize your car's performance.
A lot of stock car exhausts systems suffer from wear and tear; they lose their color and showroom appearance, but there are systems to add motorsport styling to your vehicle, guaranteeing years of the sleek look your car had when you first saw it. Car exhausts should only be made of aircraft quality T-304 stainless steel, which prevents corrosion and maximizes performance and durability. There are also specific engineering enhancements to allow for maximum flow and power.
Sport Car Exhausts Systems:
If you're looking to enhancing your VW/Audi or any other car, the exhaust system should be the first place you look. Upgrading your sport exhausts is the most effective change you can make compared to upgrading any other part of the car. Sport exhausts make your car sound better, and you'll see your mileage and horsepower go way up.
Furthermore, changing other part of the car before changing the car exhaust can actually hurt the performance of your car. Cam and chip upgrades might not work properly without first upgrading your car exhaust system. We recommend that you read up a little first before you make any upgrades. Speak to an expert or join a car forum on the net to learn more.
The iron dual outlet manifold is much more durable than the quieter tubular header. An iron exhaust manifold will yield great results when utilized with a Techtonics Tuned downpipe and sports exhaust system.
Stainless Steel Car Exhausts Systems:
These are without a doubt the most effective and highest performing exhaust systems. Auto experts have been through twenty years of reining and upgrading this exhaust system. It is made up of aircraft-worthy 304 stainless steel and includes tubing, clams, and mufflers. Depending on the type of sound you want your car to make, you can order either the system with zero, one, or two resonators.
If you're looking to upgrade your car, get better mileage, or better performance, upgrading your car exhausts system is the thing to do. Stainless steel exhaust systems will give you great durability, and sport exhaust systems are available for true grease monkeys.
