How Loud Is Too Loud?
Explore everyday sound levels and calculate recommended noise exposure times using NIOSH guidance.
Everyday sounds, in perspective.
NIOSH recommended daily exposure budget
8.0 hours
85 dBA for 8 hours; every 3 dBA increase halves the recommended duration. This is an exposure budget, not a guarantee of safety.
Sound examples are approximate and vary with distance and equipment. Below 80 dBA is not an assurance of zero risk. Impulse sounds can injure hearing immediately; at 120 dBA move away and use protection rather than treating this estimate as permission.

Can this diagnose hearing loss?
No. Uncalibrated devices, headphones and listening environments affect what you hear. An audiologist can measure hearing thresholds and investigate symptoms.
What if my hearing changed suddenly?
Sudden hearing loss needs urgent medical assessment. Do not wait for an online result. New one-sided symptoms, dizziness, pain or drainage also need medical advice.
