Alexander Graham Bell worked on devices that would help kids and adults who had severe hearing loss. One of his devices was a single headphone that could effectively deliver loud sound to a deaf person. He used a microphone that he invented, so that people could talk to the headphones that the deaf were listening to.
The device worked wonderfully, and Bell went on to invent a device that combined the headphone in the same container as the microphone. He referred to his new device as a "telephone".
Bell's last name was later used as a new unit for measuring the strength or loudness of sounds, and it was called the Bel. A Bel defines a pretty loud sound, way beyond what would be heard around the house or in town. Scientists back then thought it would work better for most things to use one/tenth (1/10) of a Bel, instead. In the metric system, it was called a deciBel. The "B" is capitalized because the unit, Bel, was taken from someone's name. The abbreviation for deciBel is dB, still using that capital "B".
