In case you, too, are wide awake, listening to jet aircraft noise, you might find these links useful.
LAX Noise Complaint Form is really hard to find from the airport website.
LAX Airport Monitor lets you view a map of the area with all planes in the vicinity. It is animated so you can see planes appear and disappear as they take off and land. All flights from near real time up the the past 3 months are viewable.
From the airport monitor, I can see that flights went directly overhead at 3000' and 3200' in the past hour. They should be flying at a minimum of 4000'. I reported them.
We normally don't hear jet traffic from LAX because the planes take off to the west, toward the ocean. However, we sometimes here them when they reverse the pattern. The wind is currently coming out of the east so aircraft takes off toward the east. The planes that went overhead then turned clockwise to head out over the ocean.
Why are they running the north LAX runway in the normal (take off toward the west) pattern and the south LAX runway in the reverse (take off toward the east) pattern? Weirdly, they are also allowing planes to land on the south runway in the normal pattern (toward the west). That requires flawless coordination and execution.
There goes another one.
At least it isn't a summer weekend with all those banner towing aircraft, circling the beach. Let's boycott all the businesses that advertise that way.
