Wow...and not in a good way..

No.... but I know some people that have a problem with EMF and WIFI. That's a real problem without hearing sound.

I have never been able to detect these high pitched sounds I have known people who could. I worked with as an HVAC mechanic and had a helper that I had to find another job because he could not be around the roof top HVAC without getting headaches and feeling ill, too bad he was a hard worker.

Just let me put my ultrasonic ears on and I will answer your question.

I can, no wait a minute I suffer from tinnitus.

Not after you turn 18 apparently (or there abouts). It is not a deterioration of hearing acuity but caused by the establishment of adulthood. Maybe biologicaĺly adults can defend ourselves from any danger making these noises.

I thought I just forgot to turn the vibrator off

Yip, sounds like the ocean ! Can we go fishing, please ? Maybe we can catch some sonic fish ?

I can't but I had a friend who lost an ear in a farming accident and had a dog's ear implanted as a replacement. Not surprisingly, his hearing greatly improved. The down-side was he began yelling whenever I blew a dog whistle. So annoying. It destroyed our friendship.

Aren't they outside of the range of human hearing? Hence the term'ultra..' But, no my hearing has been damaged through exposure to loud working environments in my youth. Our wonderful NHS provides me with hearing aids that i dontcwear often enough but even those don't help me with ultra sonics
