Did you know that the older you get, the frequency range you have decreases? In other words. Kids can hear some things adults can't. This is from high frequencies. Kids now have 20000 Hz noises as their cell phone ring tone? It's so Kids can hear the phone but teachers cant. In Germany they have malls with speakers that pump out over 58000 Hz to keep kids away from the malls after 9 pm? If you want to learn how to get your speakers to do this, go to this site which will tell you how to make it yourself!! How high do you think our ears can handle, even when we can't hear it? Why do adults have a smaller frequency range than kids? How high can man make the frequency Hz? Are you going to use this at school as your ring tone? xd

The reason some adults can't hear as well is because some of us ninja listened to our music as loud as we could burning_eyes !!!! Even when our parents told us it would make us deaf! Huh? eek And since really loud heavy metal was popular..... Huh? What did you say?!?!?! rofl
Ok, loud noises (that's what MY parents called my music) do destroy or damage the cilia (little hairs in our ears that vibrate with sound waves), and the more damage, the less you hear.....
My son has a ringtone that drives my friend crazy and I of the heavy metal concert goers age group cannot hear it at all. sweatdrop However, it does give me a headache....
Oh... and when your ears are ringing, think of it as the little cilia screaming that they aren't happy-- it usually means damage is being done or recently has been....
and I still listen to my music loud!! rofl

No it doesn't determine on how loud it is, but how high the FREQUENCY is. It can be really quiet or really loud and it wouldn't matter

Yes, frequency matters, but the decibel level also matters. Loud noise (chronic or extreme) damages hearing permanently.

I understand that but its not the decibels in this is not a factor. I'm referring to the frequency.

J'aimerai toi... Yes, but the loudness of the music/noise is a factor in why most older people can't hear the ringtone. Once the cilia is damaged by loud noises, they can't detect the higher frequencies. ...quand tu aimes moi!

It doesn't always work... some adults with good hearing can hear it, and some kids can't... I tried it.

No, it's not ok. stare
Let me explain again what I was trying to say so I won't get my head blasted off again....
I was talking about frequency, too.
QUOTE:
"Why do adults have a smaller frequency range than kids?"
Our hearing is based on the cilia picking up the soundwaves. Different cilia pick them up at different FREQUENCIES.
Think of a thousand-key piano. Aging in general kills a few of the keys, so hearing in general gets a little worse over time. There is more than one cilia or key on that piano that will pick up each frequency, so you can lose some without noticing. Listen to high (or low) frequency chronic sound even at low volume, and some of the cilia will be damaged. Like hitting the high keys on the piano with a hammer instead of a sledge hammer. (parts wear out on anything if used enough)
The louder the volume, the faster one will lose those frequencies being heard. Now use the sledge hammer on the piano.
(The music I listened to was like hitting my piano with a pipe bomb)
I have enough High frequency cilia left to know the ringtone is there, but not enough to consciously hear it.
Adults who have never been around chronic or loud sounds will hear more frequencies than those who have been around it. My father can hear the ringtone in question- he has been around low frequency noise his whole life-- but he can't hear the dog bark (big dog, low frequency bark)
My mom can hear the low frequencies, but cannot hear windchimes or the ringtone. She spent alot of time with high frequency sound during her life.
The mall you mention, even if playing the frequencies at low decibel levels, is probably making those teens lose the higher frequencies faster..... would be interesting to study!
I hope this time I have made my statement clearer by taking the fun out of it.

Thank you for your great explanation, i bet you are studying medicine.
The cilia pick up different frequencies. How do people lose their ability to "hear" certain frequency (ranges)?
I found that the cilia at the beginning of the cochlea pick up the high frequencies and the low freqencies at the end.
I wonder if the loss of hearing is a mechanical/physical problem or a neurological problem.
If there isn't a physical problem suppose that it might be possible that the brain itself is shutting off certain frequency ranges due to overstimulation. The brain hates it and it would make sure it wont happen again, even by disabeling certain cilia.
If not, enjoy the Fiction.

I've been in medicine awhile ninja Hearing loss can be either mechanical or neurological, depending on the person. Can be both, too. I'll have to do some research about your theory that the brain "shuts it off". Interesting thought. mrgreen

Yep, I guess it's really been explained already- however, I was wondering if someone could clarify a related matter;
I heard that when you hear those high-pitched noises in your ear for a few seconds (not actually a sound generated outside of your body- only you can hear it) that it is one of the cillia 'dying' or being damaged or some such, and apparently you'll never be able to hear something at that particular frequency again. Does anyone know whether this is true or not?
It does kind of fit with the theory of what we were talking about before...

Does anyone know whether this is true or not? It does kind of fit with the theory of what we were talking about before... Yes, those high-pitched noises in your ear that only you can hear, are signals that something is going on. Sometimes it is cilia "dying", sometimes it is signifying an irritation or damage. High fevers can cause them, as can infections, loud noises, high frequencies, trauma (such as head injuries), medications, etc. Everyone starts out with several cilia per tone, frequency, sound. As long as only some of the ones in a certain range are killed, you will still be able to hear those sounds/frequencies, although probably not as well. Once enough of them are gone, then forget hearing that sound again.

I hate the new ring tones; such as the mosquito. They hurt my ears because of the high frequencies. Students in my class will just play them for the heck of it. It gets highly annoying when i am trying to study/read/take notes/etc.
