How accurate is a browser-based decibel meter?

Smartphone and laptop microphones provide reliable relative readings for everyday noise comparison, though they are not calibrated against certified industrial sound level equipment.

What decibel level is considered safe for human ears?

According to OSHA and the WHO, prolonged exposure to sounds above 85 decibels can cause permanent hearing damage over time. Normal conversations average 60 dB.

Why did my browser ask for microphone permission?

The Web Audio API requires one-time user authorization to sample sound waves from your hardware microphone.
