Sones to dB SPL at 1 kHz
Type a value in sone to get it in dB (1 kHz) instantly.
96.44dB (1 kHz)
That's 3.1× as loud as busy traffic, while a rock concert is 2.6× louder. That is a loudness of 50 sones.
Convert the other way: dB (1 kHz) to sone
What it means
How loud does it sound?
For steady sounds, using Stevens’ rule above 40 phon. Fan and appliance makers quote sones measured to ANSI/AHRI standards.
The math
How to convert sone to dB (1 kHz)
Above 40 phon: sone = 2^((phon − 40) ÷ 10); phon = 40 + 10 × log₂(sone).
Example: 50 sone = 96.4386 dB (1 kHz).
