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!
Fiction
2005 IDW continuity

The Functionist Universe
A member of the Anti-Vocationist League, Decibel had risen to prominence in the organization, earning him a spot on the bridge of the Last Light. When the crew of the Last Light found themselves being chased by the Functionist Council's puppeteered Cybertron, they soon wound up in Megatron's native universe with Decibel alarmingly noting the portal home had closed behind them.

Vintage G1
- Mini-Cassettes 3-Pack (Multipack, August 8 2019)
- Accessories: Left and right "Fire Blasters"
- In a surprise move, Graphy and Noise (now called "Gurafi" and "Noizu" because of stupid reasons) were reissued as part of the Vintage G1 series, in a 3-pack alongside an inexplicable "Decepticon Frenzy". This version of the pair came on a retro-styled 2-pack card, with Frenzy all alone on his own same-size card.
- Despite the ridiculous hyperliteral romanization of the components' names, Decibel managed to keep his actual name in the product descriptions.
- This set was revealed when it went up for preorder on Hasbro Pulse on the first day of San Diego Comic-Con 2019... despite not being announced at the show at all.
Notes
- Decibel plays lefty guitar as part of a band that includes Slamdance and Legout on the retailer incentive cover to Spotlight: Blaster.
