Sure, positive mindset is important, but it can only take you so far when northern wind makes you cough because there is a dozen factories out there, or when you are chronically sleep-deprived because a noise source you might not even know exists switches on at ungodly hours.
Low-frequency sound waves can be brutal. Something can just happen to resonate where you are, but meters away everything is fine. To make things even more interesting, go low enough and you might not actually be hearing it per se, but feeling it with your body. Good luck explaining it to people who can enact change.
Relatedly, Benn Jordan investigated[0] certain sound that some refuse to believe is real yet others suffer from.
However—since you mention getting out of your (presumably otherwise quiet?) house onto the street—I also encountered a phenomenon in which presence of subtle other noise (which in your case could be tree leaves rustling and so on, and in my case was a literal white noise machine) make a sound that in a completely quiet room would drive me insane significantly less of a problem. This is not to say “it is all in your head” because, well, how you perceive it is what matters at the end of the day.
Hopefully your bass player neighbour could understand and use headphones or practice at a different time.
I'm certainly not the only one in my neighborhood who would go postal if I had to live in a "quite" neighborhood where people complain about the noise each other's landscaping services make and call the cops when parties run late.
Turned out it was one particular ferry in the harbor. It was a smallish catarmaran fast ferry and when it was coming in a curved path it was like a narrow beam of infrasound funnelled between the hulls swept around and rattled our place 5km away. It took quite a while to notice the pattern, but was a great party trick to see it coming and predict the rattle to guests.
Apparently it leaked to much water into the ground nearby that shocks were transmissible. Whenever a heavy lorry/truck drove along that road late at night, it would shake the building a little and rattle plates in the same way.
When they finally fixed it (after the road got beautifully resurfaced by the council, then dug up 3 days later by...Thameswater) presumably the water fell down into the water table and we've not had any shaking since.
There are several places in Britain (and elsewhere, I imagine) where beam engines have been preserved and are periodically run using live steam. the engines themselves are quiet by modern standards, though I believe the machinery they drove often produced a racket.
There are confounding factors of course, like direction and what's in between. E.g. do you sleep in a room that's on the opposite side of the house with windows closed and good insulation/windows? You'll probably be totally fine.
Do you sleep in a room that's towards the source and with the window open? Oh you will very very much hear that train, especially if the wind is coming from that direction.
Sleeping outside? Oh you will very much hear that train!
The pump it drove could have been loud, though.
You get the same effect over a smaller area with vibratory compactors used in construction. Get the frequency just right and the whole neighborhood can feel it.
Some may have real symptoms, but the cause is something else inside or outside them.
Turns out, back in 2016 a German study[0] has found damage to trees near the towers—starting on the side of the tree facing the tower, then spreading to the entire tree.
This study, of course, does not show whether that measurably harms humans, but I stopped thinking those fears and complaints are completely unfounded.
I don't know what you have to do to get a link on PubMed, but it definitely isn't much.
[0] Although I have not seen anyone in this thread tell me that this paper is false—it was mostly appeal to author’s preexisting reputation—I’m taking it at face value.
(Basically, everyone was even more chronically online during the lockdowns, so there was extra money to be made and extra urgency in rolling out telecommunications infrastructure.)
While I wouldn't subscribe to standing in front will cook you idea, opening the door prematurely does give off radiation. Standing in front of a microwave beam dish may be a different story - knew an ex-Telecom tech who told a possibly tall tale of cooking chicken.

Unsurprisingly, this disturbs many people's sleep.
Moving outside of cities doesn't even solve the problem because low frequency noise travels for miles, highways go everywhere, and aircraft are inescapable.
And the EPA has simply abandoned any attempt to regulate noise pollution.
