i have no idea but the landscape here makes it even worse because everything is surrounded by rocky slopes and the sound echoes across all over the place
first place i rented when i got here was in front of a primary school. because flat land is scarce here, they run the kids in their break times in a cycle so about half of the daylight hours there is screaming kids running around in the playground outside, which was like 30m from where i was located. all. fucking. day, screaming kids.
not only the screaming, but i started to stand on the balcony and watch how they behaved and man, all the boys were constantly play fighting with each other. like, because they were jammed together in such a small space all the time they didn't have any other kind of game to play. these weren't countrty kids, it was fairly dense urban area. but, having said that, almost anywhere you sit for a bit on this island you will hear the sound of farmers chipping away at their fields or grape vines or the goats (mostly goats) bleating as well. so, idk, maybe madeira really is mostly a rural place. but they are even louder in the dense urban areas like caniso and funchal.
i could not have tolerated living in the environment of funchal, where most of the bitcoiners have set up shop. i couldn't stand it even in ginjas, a little suburb of Sao Vicente on the opposite side of the island. it's not just the yelling people either, they all have dogs that they also confine in these tiny spaces and the dogs just yap yap yap all fucking day long.
