We don't like any sounds that are between the sound frequency of 2000-5000 Hz nails on a chalkboard is in that range along with knife on a bottle and woman screaming with terror and noises related to cotton wool and babies crying. It's the range at which our ears are most sensitive for some reason. They haven't figured out why that is just yet. I think they went in the direction of trying to link it to evolution and apes and that didn't work out so now they're back at the drawing board. But yea anything between 2000-4000 or even up to 5000Hz we don't like.
I was about to comment on chalkboard nails, until I saw this post, Jewel. Someone who understands frequencies. From age 4, we all played the tricks of nails, regularly, to surprise the teacher. No problems with all that. As with a fart cushion. Winding, scrolling Blackboards were all used throughout my education, to 1998. So I envy those who got the privilege of whiteboards and flipcharts.
Ooh, kids in supermart. It takes effort to reign my cold frustration. I know the frequencies I like: NOT THE HUMAN VOICE. Telephone, and its filters and bandpass compression to omit detail. The assumed 60 to 7000 Hz is where I admit I'm more comfy at the lower end (male) than the screech. Female TV presenters are annoying - OK - that's my board nail hate, for sure. I like a lady who I meet in person, without the screech.
My serious sound preference is 10 Hz for a proper, fullsize subwoofer array of bass bins and scoops, in an open space, which doesn't get to the ears. It makes your belly wobble. I like electronic music, with no human voice element. What matters is the power of the generator, from humble 1,250 watts, or multiple several 50,000 watts for the amps
60 Hz does it just right in my car subwoofer setup. All highpass is 160 Hz upwards for midrange and tops.
Umm... cracking a coconut. Not a friendly fruit
