Answer to the question “Who was the decibel named after?“
The decibel is a unit that represents the intensity of a sound. It’s equivalent to one-tenth of a bel — named for one of the inventors of the telephone, Alexander Graham Bell. Decibels are measured by the “A” scale, which approximates how the human ear responds to a frequency. A normal conversation rings in at about 60 dB(A), while a chainsaw measures about 110 dB(A). Prolonged exposure to high-decibel sounds — generally above 85 dB(A) — can lead to hearing loss.
