This sounds so beautiful and desolate, reminding me of a combination of the first two tracks from Aphex Twin's Selected Ambient Works Vol 2, disc 2, in particular "Blue Calx" and "Parallel Stripes" starting from 40 seconds. [0] Thank you for sharing. [0] https://www.youtube.com/watch?v=FXBAU8HsAqk

Soon as I read your comment I laughed and said now let’s watch YouTube remove this video for copyright infringement

The expressway I-5 bridge in Seattle is notoriously loud and can be heard for miles around. Interestingly, the sound from the busy topmost lane doesn't seem to make it to the ground. You can verify this during the brief pause when the express lane changes directions. I believe the traffic noise from the express-lane is reflecting off the underside of the upper lane. Seems like a diffusing layer on the underside of the upper lane would reduce the sound getting to the city below.

2) It's amazing how perspective changes with more information. It is very odd how much that sounds just like a mower having difficulty starting, and is exactly the conclusion I would have jumped to it being. Glad you were able to get a better answer.

Are the birds imitating sounds they heard in the forest? Mimicry is a powerful thing

I went deeper down the rabbit hole, and it is their mating call / territorial signal. The drumming sound is actually created from a vacuum effect caused by the particular movement of their wings. https://www.youtube.com/watch?v=vERkh23mp64

I tried making a spectrogram: https://twitter.com/nibot/status/1269347206445756416

I tried using baudline[1] (a 20-year-old program!) but it didn't work out-of-the-box on my current Linux installation. Instead I found something called Sonic Visualizer[2], which, while not real-time, worked out of the box. Using Pulse Audio 'pavucontrol' it was easy to configure Sonic Visualizer to use as its input the 'monitor' channel, i.e. capturing the audio while the video played on Twitter.

I'd love to get baudline working again since it's able to run in realtime.

It looks like the main tone is at 440 Hz and tones at 400 and 480 Hz come and go. Not sure what to conclude from this. :-)

That you should take a tuning fork to the bridge and listen for beats?

I think the complaints about Falmouth wind turbine noise are eerily similar to complaints that wifi gives people headaches. I don’t think they are founded in reality.

My parents lived up that way, and the amount of NIMBY-ism regarding offshore turbines is staggering. I suspect you may be right, and people just latched onto whatever claim got the turbines shut down.

It is also possible that they generate the sound of the same frequency, but coming from multiple sources it can compound in some areas to be louder than elsewhere - and those areas could change with the direction of the wind.

This is purely speculation from my side of course, as I've never been there.

As a horror film fan, I was thinking combustion powered chainsaw.

The lyrebird can imitate a chainsaw -- among many other things. This is from the BBC's Life on Earth. https://www.youtube.com/watch?v=VjE0Kdfos4Y

That’s amazing, thanks for the share! I’m one of today’s lucky 10,000.

Alas, the US seems to care little about the lives of people who live near the expressways.

Berlin has some absolutely beautiful church bells. The overtones and reverb from all the walls are so chilling, it makes you feel like you're inside the bells or something. I recorded one of them: https://sndup.net/2h7t/St+Joseph+Kirche.m4a

yes but the difference if that you hear the sound a couple of times per day vs continuously
