Noise Exposure Dosimeter Calculator
Calculate sound dose percentage and maximum permissible exposure time based on NIOSH and OSHA decibel limits.
Input Parameters
Enter details for calculation.
Daily Allowed Dose
Expert Tip
NIOSH uses a 3 dB exchange rate with an 85 dBA exposure limit. OSHA uses a 5 dB exchange rate with a 90 dBA limit.
Calculation Methodology & Details
Formula
Computes the fractional sound exposure budget used based on decibel volume and duration.

ℹ️ About this Calculation
This ophthalmology and otolaryngology (ENT) clinical calculator evaluates visual acuity metrics, intraocular lens power, audiometric hearing threshold shifts, voice dysfunction scores, and occupational noise exposure limits based on AAO and OSHA standards.
Variable Glossary
Sensory & Biometric Measurements
Snellen fraction (20/20), LogMAR, corneal keratometry (K), axial length (mm), audiogram decibels (dB), or dBA noise levels.
Clinical Assessment Scales
Target IOL diopters (SRK/T formula), pure-tone average (PTA), GRBAS dysphonia grade, and daily noise dose percentage.
How to Calculate Step-by-Step
Step 1
Select visual acuity notation system (Imperial Snellen, Metric, LogMAR, Decimal) or audiometric frequency thresholds.
Step 2
Input ocular biometry parameters, sound decibel levels, or voice acoustic ratings.
Step 3
Review converted vision scales, recommended lens implant diopters, or hearing impairment classification.
