Common Scenarios

Acoustic engineering, headphone reviews, and factory noise testing (compliance is often <85dB) widely use decibels.

History & Background

The decibel (one-tenth of a Bel) was originally created to measure signal attenuation in telephone lines, honoring Alexander Graham Bell.

Conversion Details

Decibels (dB) is a logarithmic unit. The conversion formula is: dB = 20 × log10(Pa / 0.00002).

The faintest sound a human can hear is roughly 0 dB (20 µPa).
