Decibel
- Decibel is an Autobot Mini-Cassette combiner from the Headmasters portion of the Generation 1 continuity family.

The combined form of Noise and Graphy, Decibel (デシベル Deshiberu) possesses Graphy's speed and Noise's power. Decibel is loyal and obedient to Twincast, but comes off as overly prim and proper to the other Cassette Transformers. His shoulder-mounted Fire Blasters can generate heat up to 9000° C. Decibel is the older brother of Legout. What relationship this gives his components, Noise and Graphy, to Legout is unclear. Perhaps they're half-siblings. Ha!
