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...

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...

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...

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...

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...

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.
