Headphone Sensitivity Units

Convert a per-mW sensitivity rating into a per-volt rating.

Sensitivity (dB SPL / mW)

Nominal impedance (ohms)

Your result

Sensitivity (dB SPL / V): 106.9691

How this works

dB SPL/V = dB SPL/mW + 10 × log10(1000/R)

Use the result carefully

Compare ratings only when manufacturers use comparable measurement methods.

Calculations run on your device. No audio uploads, account, or email required. Numerical outputs are rounded for display; these tools do not analyze a recording unless explicitly stated.
