There are even more sources of noise in a small urban neighborhood.
Last night I found three more sources of 'weird' sounds and some other
sources of loud sounds at night.
One was a slow repeating bubbling sequence at midnight; one might mistake it
to be a washing machine cycling slowly; it was quite loud enough to bother
sleep. I went outside to check. The neighbor at the far end had his garage
left open. The noise was coming from inside, getting reflected from the
opposite building and reaching my house almost without loss of strength.
Initially I thought it must be the washing machine inside. But, on second
inspection, I found that it was not. It was coming from the water-heater
area nearby. Possibly a hidden speaker set/transducer there ?
Another was the new lighting outside the garage doors. Most of the old flat
small bulbs have been replaced with compact coiled (antenna like)
flourescent tubes. One of them was giving out a directional high-pitched
audio tone pointed down the road.
Even a community street light (yellow) (or its lamp post ?) was emitting a
Area utility transformers seemed to be emitting a buzz that could be heard
10 - 20 ft away - that was not too loud.
Passing cars and trucks are significant sources of noise at night ! They are
very loud. I found that garbage trucks are an order of magnitude louder than
even that. Those trucks have something wrong with their construction.
One interesting difference I noticed between last night and the night before
was the total lack of background noise. The night before I had heard a very
very loud background roar that I assumed was due to 'freeway traffic' - 1/2
mile away. Last night that noise was completely missing ! I think this is a
new source of noise that is yet to be identified. It is probably something
originating from the airport area (farther away) and not at all traffic
noise from the freeway ! It is hard to imagine heavy traffic at night on a
freeway that would be needed to create such loud noise.
Noise reduction/elimination must be made part of every design. Automobiles,
homes, neighborhoods, even aircraft. < Passing aircraft completely blanket
the whole area with noise of all kinds of frequencies ! >
I believe this is achievable with today's technologies.
