I have been having trouble sleeping lately, and though I doubt it is because of ambient noise, I decided to use a pair of ear plugs. When I put them in, everything that I heard in my room before seemed to be quieter. But, they didn't seem to block any of the extremely high-pitched ambient noise - like my roomate's TV and computer monitor and the streetlamp outside my room (I think that's where the noise is coming from). When I take the ear plugs out, I can still hear those noises, but they are made less annoying when the other ambient sounds are there to help drown it out.
They say that human hearing is at a range of 20-20,000hz.. Is that a set range? I swear I can hear things we're not supposed to hear - like my wireless router makes a high-pitched sound and so does my cable modem. When I plug in AC adapters - the big bulky ones - I can hear them usually, too. I also hear dog whistles - and not just up close.
Am I making this up in my head or am I actually hearing them? Also, when I put the earplugs in, are these high-pitched noises in my head or am I actually hearing something?
Is there any way to make the high-pitched noises go away when I try to sleep?
