If you cut the number of flights in half, you reduce the amount of noise, so yes, it would reduce it, but you have to keep in mind that in order to meet their goal of 90 million passengers, they're going to have to bring in larger planes, and larger planes make more noise. Even if you're bringing in fewer planes, I'm not convinced that the total noise dosage would go down, and that's important. If you have fewer flights, you get less noise. Whether 9,600 is the right number, I don't know, but I just think 19,000 is not.
