I wouldn't say that I enjoy it necessarily, but I heard an MRI machine recently for the first time and it makes the most bizarre collection of sometimes comically comouter-y sounds. People told me it would be loud but I didn't know what type of sounds I would be hearing lol.
I work in a place where machinery is always whirring and I don't find it particularly enjoyable. Our machines are more just sort of droning as opposed to something interesting.
