dubbio quantizzazione...

Ciao a tutti,
dato questo esercizio:
come si calcolano i bit di quantizzazione necessari a garantire un rapporto segnale/rumore di 48 decibel e l'audio ha una dinamica massima di 60 decibel ???

i bit si trovano facendo DB da preservare/6 giusto? quindi sarebbe 48/6 = 8 ... ma la risposta corretta è 18, perchè?
