Those high pitched anti cat devices

A lot of my neighbours have high pitched beepers on motion sensors that I'm told are supposed to deter cats. Can anyone else here hear them? I'm pretty sure all kids can hear them but I still can in my mid 20s and other adults don't seem to be able to.

I'm sure people who have them don't realise but they're so hostile to people with sensory sensitivities, especially when the range is quite far so they go off when you walk by on the pavement. Maybe it's a me problem but I'm sure I'm not the only one
