I’ll start: I love listening to the washing machine running. Relaxing, sounds like hard work I don’t have to do. Looking forward to the clean clothes and nice smell! Sewing machine sound makes me all giddy. Sound of my 1988 car engine.
I find chain saws and brushcutters extremely annoying. On some days in spring and autumn I can get quite grumpy about it, even though I rationally know they also save a lot of hard work.


Sound of Inline 4 motorcycle sport bike. Not the high rake supersport with loud aftermarket pipe, but the stock pipe on a comfort sport bike.
It burbles like a purring cat when idling, and comes to life when accelerating; with a mix of high revving engine, the intake and exhaust noise, the transmission whine, and the subtle tinkle noise of the chain going over the sprockets. Its like a beautiful cacophony.
I hate gas leafblowers, those should have to be electric only.
I’ve always been partial to triples myself, in terms of exhaust note
Yeah, a friend of mine loves the sound of twins. (The engines, not the babies)
