Let say if you are around 85 decibel for about two hours according to the guide you dont need to use earplugs because it is still less than 8 hours right? ike you would only use earplugs if it is 85 db for nearing 8 hours lets say you gonna be in it for 6 hours then you may want to use earplugs...

I know that , I am not trying to see how long I can listen to these loud sounds. I am trying to use it as a precaution as when to use earplugs if I am exposed to loud sounds. Because I don't think I should be wearing earplugs if I just listen to 5-10 minutes of 90 decibels. You get me? So I...

Can someone show me how to use or read the noise chart of 85 db 8 hours http://www.noisehelp.com/noise... Read detail for question? For example the guideline allows me to listen to 91 db for 2 hours without earplug and if i rest for the remaining day or 22 hours i can listen to 91 db for 2...

http://www.gcaudio.com/resources/howtos/loudness.html Correct me if I'm wrong but is this guide saying you can be exposed to 90 dB for 8 hours a day without earplugs? And it renews after you rest your ears for the remaining day or 16 hours. Then the next day you can be exposed to 90 dB for 8...

Oh no I'm just asking if this was what the guide is saying

http://www.gcaudio.com/resources/howtos/loudness.html Correct me if I'm wrong but is this guide saying you can be exposed to 90 dB for 8 hours a day. And it renews so you can be exposed to 90 dB for 8 hour again the next day.

I wanna ask what do you do to preserve your high frequency 8khz-20khz? and how old are you? Like do you wear earplugs in everyday environment such as driving, walking in the street, eating in a restaurant, office work, grocery shopping etc/ When do you start wearing earplugs (do you follow...

Hi how long can we walk in your average street 75-80ish db? and be safe?

Do you need to wear earplugs walking on the street, eating in a noisy restaurant 75-80 db, driving, doing grocery shopping, basically daily day-to-day activities do where decibel is 75-80 , do you need to be wearing earplugs because now there is 50 db at 6khz and 70 db at 8khz presbycusis...

Do you have a hearing loss in which frequency is it?

Do you have a hearing loss if yes, mild, moderate or severe or perhaps the gradual sloping audiogram due to aging?

is it because you are borned with 20000 hair cells, and with hearing loss you just lose a number of hair cells, but the remaining hair cell are healthy therefore they take the same amount of intensity 85 decibel for 8 hours to damage them as if compared to a person with normal hearing... having...

in cases with hearing loss like these. do you guys still use the same hearing loss guideline by ohsa saying the damage takes 85 db around 8 hours? or are your ears a lot more susceptible and easier to damage at a lower decibel now with the hearing loss let's say it might take only 80 decibel...

For example it takes a normal hearing person 85 db for 8 hours as a guideline for hearing damage. When you have a hearing loss ( mild, moderate, severe...etc.) do you use the same damage criteria that is it will take 85 db for 8 hours to damage your remaining hearing or is your ear since it has...

I read studies that shows nac + alcar combined has a better protection, http://www.ncbi.nlm.nih.gov/pubmed/15966690 So I see there is a huge thread on NAC alone, but is there anyone who take alcar at the same time with nac prior to noise exposure or after? How many mg of alcar is it...

Here are the links : http://www.ncbi.nlm.nih.gov/pubmed/10491957 http://www.thegoodear.com/docs/restoration_of_hearing_loss_.pdf also there are many more studies, just google "augmented acoustic environemnt" but they all have the same implications, delaying hearing loss and also restoring...

Right, i know its not cure as in restore his hearing 100% but did they successfully grow some hair cell back for "some" increase in hearing?

WAIT so there is finally success at curing some hearing losss on human?!!! OMFG did I just read what I think I just read? please confirm me!

There seem to be 2 hearing loss types we need to prevent! the first is the 4khz noise notch, usually due to the anatomy of the cochlea, if you were exposed to significant noise, usually it will be a notch at 4khz...and recover at 8khz. And then there is the second hearing loss-aging-related...

Actually i also saw one post on here by xanaxvictim who posted her audiogram and she can hear up to 20khz at 10 db! Let me message her and see if we can get detail on her lifestyle ... the idea I want to get out of this is to get many stories and examples see we can learn how to prevent...

Guys also take a look at this http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2868117/ This goes to further kinda support telis, asian, and bwspot's ssuggestions that noise isnt a big contributor to aging. that in fact, it is lifestyle (diet, stress,etc.)... Hey telis, bwspot and asian, can you...

Just curious if we start to lose our really high frequency 8khz-20khz with age? So we can't hear 15khz by the time we are in our 50s? Then by the time we can only hear up to 10khz, is it the time when our speech range will be affected by age-related hearing loss right? And this is primarily...

"For me the domino effect is: 15 kHz can only go after 16kHz has gone. 16 can only go if 17 kHz is gone" yeah i think this is the case too.

I have a question though, which is traditionally thought of as age-related loss or presbycusis, can we preseerve 8-20khz by having low noise exposure and a sound diet to prevent the nerve from degenerating/

that is the domino effect! exactly! because the sound waves hit them first, so there are the first to bend,; and follow by the next lower frequency

yes, this is what my point is about

basically in this thread, i would like to understand whether there is a relationship- that if you have normal hearing 0-8khz, does that imply that you can hear high frequency 8-20khz or at least hear up to a certain high frequency like at least up to 16khz if you have normal hearing... and...

Ah, I was unsure of what you were saying, but you are saying that how do we not that 8-20khz didn't just appear in the year 1900 instead of 1000 b.c. hence you said "how do we know if it is not a recent thing right?" IF this is so, then that is not possible because biologically evolution takes...

NO , I never said it is there for human speech , they are for localization of speech and spatial perception on a 3d dimensional plane, in other words without these high frequency you cannot localize speech, if there are multiple noise source, you won't be able to discriminate them. That's not...

You guys better believe it, but a lot of people and including stupid audiologists tend to think that you don't need 8-20khz. But if you think about it, come on! Are we that stupid to think that mother nature want to waste energy on nonfunctional useless cells? NO WAY . And we gotta remember the...

oh so what you're saying is noise doesn't really cause damage in the 8-20khz , you lose them from 20khz and downward gradually by age or ototoxic medicine ? usually damage by noise is only seen at 4khz? right?

Is it by noise or purely by aging? I know the medical literature says that noise-induced hearing loss is usually a big dip at 4khz, but can dip occur at 8-20khz? Can noise completely kill off really high frequency, or is it generally by age?

if the environment has intermittent noise of 85 decibel, and the exposure chart say we can be exposed to it for 8 hours straight, does this mean that given intermittent noise, we can be expose for even longer than 8 hours like 16 hours?

When people say their hearing has remain the same for a couple years, are they talking about 0-8khz only? What about 8-20khz? can we protect that so it remain the same too? When we have noise induced hearing loss which frequency is the dip seen at ? Can noise induced hearing loss occur at...

I just wanted see how long has people audiogram stayed the same.
