Why are planes so loud tonight?

During the day, when the air is warmer than the ground, noise energy from an airplane staying in the air, so while you can still hear it, it seems quieter. Conversely, at night, when the ground is warmer than the air, the noise is drawn down, making it seem louder.

Why are the airplanes flying so low over my house? Aircraft are limited in the direction they fly because they must land into the wind. Therefore, the flexibility of air traffic is dependant on the wind patterns of the day or, even, the hour, as winds can change rapidly.

As for the ground, you're hearing more wind noise than engine noise, but since the sounds combine, and travel through clean air with absolutely nothing to disrupt or deaden the sound, it hits your ears very clearly.

The reverberation of sound waves caused by weather may make noise seem louder than it actually is. Common factors responsible for this phenomenon include: variations in air temperature; wind speed and direction; humidity and precipitation.

Departures tend to be louder than arrivals since the pilot is using more power to the engine to achieve lift.

In the longer term, after 2050, completely new aircraft geometries that use blended wing designs, and even aircraft that change shape will potentially lead to major reductions in airframe noise, greater efficiency and improved environmental impact.”

Jet airliners, on the inside, are loudest in the last few rows at the rear. Outside, right at the engine exhausts, but you're in serious danger from the engine if you're anywhere near that. Most of the noise goes backwards away from the plane.

In my own unscientific research, dozens of decibel readings I took on recent flights show where you sit makes a difference in how much noise you hear. Sitting next to or behind the engines makes for a noisier ride. Being near an exit door can up the decibels, too.

Various studies cited in the studies indicate that sitting in front the wings and engines is the quietest place in flight, with behind the wing and engines being the loudest. That makes intuitive sense.

The Federal Aviation Regulation (FAR) Part 91.119 indicates that, except when necessary for departure or landing, the minimum altitude over urban areas is 1,000 feet above ground level (AGL) and 500 feet AGL over rural areas.

MORE DETAILS

Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.

According to an interview with Richard Taylor of the CAA in Traveller, there are laws in place that dictate aircraft must not fly below 1,000 feet over a built-up area, or 500 feet over any person, vehicle or structure.

Question: Right after takeoff, it often seems that the pilot slows down and the plane drops somewhat. Why is that? I have noticed that it is pretty consistent. Answer: The sensation of slowing down is really one of slowing the rate of acceleration; this is due to reducing the thrust after takeoff to the climb setting.

Airplane noise can be very annoying, especially if you live or work near an airport, and you should know that experiencing that noise constantly can be bad for your health. Some of the negative side effects include high blood pressure, increased risk of stroke and increased risk of heart attack.
