Electric wood sander sanding a sheet of ply wood. Hard, loud and abrasive sound, high volume low pitch. Recorded inside a workshop with a zoom h6 recorder. Audio was post-processed to boost the audio. Wood sander was a bosch 230v.
Extra loud train trip, few groups of people were loudly talking. One group of silesian accent speaking man can be heard the most, they are laughing much.
A fan with an interesting scrambling pattern. It's amazingly loud! some footsteps and other "dirt" can also be heard, but this gives some contrast to how loud the fan actually is. Field recording from helsinki, finland. Check the geotag!.
