Can you hear 'those' ringtone?

[someone]

The audio theory behind this is that as the ear ages the ability to hear high frequencies decreases.

Therefore, while the normal hearing 15 -16 year old can hear 17KHz (the freq used) clearly, anyone over the age of 25 will be unlikely to hear it.
This is the result of normal hearing deterioration due to age.

Those of you who jam at loud volumes will not really be affected as there is not much going on at 17KHz when you play live (maybe some high harmonics of the cymbals). The bulk of the volume when you play live is in the 1 - 4 KHz range. Loud jamming can result in an audiometric notch or loss of hearing sensitivity in this bandwidth. you will find problems making out what people say but should still be able to hear the "silent" ringtone at least until your 18.

the problem is, are these handset able to reproduce those frequency? and at what db?

i have sent a few emails to mobile phone companies, hope they will reply soon.

 

[sleepykitty]

soft, that's one cute avatar!!

 

[rylche]

Found one here. Don't know if it's really reproducing at a high pitch though. I hear it as a long beep.

HF Ringtone

 

[suckasucks]

ah. the old mosquito tone i presume. really irritating when you actually can hear it.

talk about piercing highs.

 

[rylche]

Sounds like certain guitarists' tone! And bassists too.

 

[Xypher]

N70 also can.. n70 speaker is mono and is very trebly.. the bass sux.. SE owns nokia at speakers i think

 

[markedymark]

these ringtones never fail to annoy me. :evil:

 

[deathism]

gosh im so deaf and tone deaf..

i cudnt hear the ringtone on the link..heard a short ring..den nothing at all..


i tink tt ring itself damaged my hearing..

 

[soft]

it could be due to your speakers that you can't hear it. this is the reason why sound engineers spend quite a bit for their monitor speakers.

this is why i am wondering if the phone speakers can actually reproduce a tone that is 17khz?

 

[Kaye]

AH! I hate that. I get very irritated with that. I shall try it on my brother later on.

 

[someone]

i guess the obvious answer is yes they can..
because kids really do use these tones and as mentioned adults (e.g. librarian's) cant hear it.

It would be interesting to see how dogs react to these ring tones cause they can hear way higher than humans!

regarding the speakers, its actually easy to reproduce high frequencies... the thing that audio guys go for is linear reproduction... HP speakers are small so they can produce lots of HF but they are quite lousy at reproducing LF

 

[deathism]

lmao..i feel so comforted..BUT..im using headophones..those big ear cup type.. :lol:

 

[visa]

my school's choir teacher can hear it and he's quite old

 

[rylche]

I tried it on my dog. She sure can hear it man. I turned it way up, and both she and I almost had our ears bleeding. Haha. Dogs can hear up to 60khz! Way above our hearing range.

 

[piano_ex]

rylche .... omg .... dog torture ... LOLX! =)

 

[deathism]

arrest rylche!

animal abuse..but knn..wad abuse is there if its juz sounds..besides...the dog's bark is worse..

and my chinese neighbour has a cute but stupid dog which barks at people..


i can walk past their unit 6 times a day for the whole week..and the barks never fails to dog!!


*edit: and the dog never fails to bark.

 

[Gr3yF0x]

it hurts like a bitch when it's right at your ear. like your eardrums are gonna burst or something

 

[BadgerS88]

I cant hear it on the link. But im only 19 and im a sound engineer. Omg I feel so ashamed.

yeah I heard the mosquito-ringtone.wav (it's at 16khz-17khz), it's clear to me maybe cos i'm really sensitive to high frequencies. it's the sound of that "electronic" frequency when you first turn on those CRT TV sets. that's how you can hear if someone's watching TV in the living room (even on volume MUTE) when you were a kid, at least for my childhood.. but now doing hearing tests I can only go up to 19khz - 19.5khz (at -18db to -6db) the most. (at age 24)

in reference to here :
http://hypertextbook.com/facts/2003/ChrisDAmbrose.shtml
so average healthy human can hear 20hz - 18 or 20khz.

coming from me, i believe you all should protect your ears often (simple $3 earplugs would do) because you only have one set of ears for one life time. medical science has advanced to penis implants, but not eardrums ones I think. for you heavy rockin musicians, subjecting your ears to years of abuse during jam sessions, one fine day you'll kena this thing called "Tinnitus". I suffered it last month for 2 weeks (lets just say I had a little hearing accident that caused it). my experience with tinnitus was exactly like what I hear in that mosquito-ringtone.wav whenever I close my ears. and this includes whenever every night i'm trying to sleep. imagine the feeling of your eyelids stapled to your eyebrows and you're not allowed to sleep at all, but in the "hearing" version. you close your ears , hoping for silence and yet you hear it even clearer! so yeah i'm glad it's gone now. i'm fine. hope my incident will "scare" you little boys and girls to think twice about cranking amps without protection.

BadgerS88 : i got a good friend, audio engineer , his works are played on radio etc. working overseas in a huge studio now.but guess what, he's born damaged hearing in his left ear. and his right ear can only hear up to 15khz . it's not how big-range you can hear, but how you manipulate the frequencies to your advantage via skills/emotion/experience/knowledge. thats audio engineering. you can only make the best out of the worst you got. so.. cheer up hehe.
