Press 'start test' and note the age displayed when you can no longer hear the sound. Then the hearing threshold in the baseline audiogram at 4000 Hz (5) is subtracted from Occupational Safety and Health Administration Enter 90 dBA, 2 hours and 30 minutes for location 1 and 85 dBA, 5 hours, and 30 minutes for location 2. A threshold shift of 20 dB exists at 4000 Hz between the audiograms taken at ages 27 and 32. Finally, regarding hearing protection, NIOSH indicated that the noise reduction rating (NRR), a single-number, laboratory-derived rating that the U.S. Environmental Protection Agency (EPA) requires to be shown on the label of each hearing protector sold in the United States is not adequate. 31-34 mos ~ 2.5 – 3.0.

Today is August 21, 2008. The difference represents the amount of hearing loss that may be attributed to aging in the time period between the baseline audiogram and Luckily, hearing aids don’t need to. Using the same formula from the previous example, you have: [(29 -7) x 0.5] = 11 dB. to prevent further progression of hearing loss. criteria document entitled "Criteria for a Recommended Standard . hearing level by adjusting the most recent audiogram. For example: “Susie” was born August 21, 2001. For example: “Susie” was born August 21, 2001. Next, add 5 dB to this field-adjusted NRR. (The Master Calculator and Age Projection Calculators will determine the degree of presbycusis in the initial audiogram. A Standard Threshold Shift (STS) occurs when the current audiogram is compared to the baseline or revised baseline and a change of 10 dB average occurs at the frequencies of 2000, 3000 and 4000 Hz, and allowance has been made for aging from the presbycusis charts provided in the appendices of 1910.95 noise standard.

CHRONOLOGICAL AGE: How old a child actually is. A threshold shift of 20 dB exists at 4000 Hz between the audiograms taken at ages 27 and 32. It is a measure of rate of change and not a measure against an age-related target. (iii) The differences calculated in step (ii) represented that portion of the change in hearing that may be due to aging. Thus the age-corrected threshold shift would be 17 dB (as opposed to a threshold Occupational Safety and Health Administration, Regulations (Standards - 29 CFR) - Table of Contents, Severe Storm and Flood Recovery Assistance, Occupational Health and Environmental Control, Calculations and application of age corrections to audiograms.
