Understanding Hearing Health
The human ear can detect sounds between 20 Hz (low bass) and 20,000 Hz (high pitch). With age, we lose sensitivity to higher frequencies. Sound intensity is measured in decibels (dB), where prolonged exposure above 85 dB can cause permanent hearing damage.
Key Formulas
- Safe Exposure Time: 8 / (2^((dB - 85)/5)) hours
- Age-Related Frequency Loss: Max Frequency ≈ 20000 - (Age * 100) Hz
Examples
Concert (100 dB)
Safe exposure: 1 hour (without protection)
60-Year-Old Hearing
Max frequency: ~14,000 Hz
FAQs
What's safe daily noise exposure?
≤85 dB for 8 hours. Every 3 dB increase halves safe time.
How does age affect hearing?
After 20, we lose ~100 Hz/year from high-frequency range.
