That is a missunderstanding. Decibels are never doubled. The ratio or the factor can be doubled.

Doubling means the "factor 2". What does doubling of a "sound" mean?

Doubling the (sound) intensity is obtained by an increase of the (sound intensity) level of 3 dB.

Doubling the sound pressure is obtained by an increase of the (sound pressure) level of 6 dB.

Doubling the loudness feeling is obtained by an increase of the (loudness) level of about 10 dB.
