Hey @jaynie! Jude being an HSP, I'm not surprised he has certain noises he's very sensitive to... for me, ir can be something as simple as an unbalanced fan on the neighbor's air conditioner that puts a squeak-whap-squeak-whap vibration in the air... or a leaf blower or string trimmer being used somewhere. Most people would simply tune it out, but I experience it as a protracted nails-on-chalkboard thing. Ugh!

I have music going 90% of the time, too... because... well... music is my mind-altering substance of choice. That's "different," somehow...

But I think a lot of noise is also the result of the many people on the planet who are simply not comfortable being alone and in silence with themselves... so they create "noise" to override that silence inside they are so uncomfortable with.
