  • Deafness

  • Inability to hear sounds.

  • Decibel (dB)

  • A term representing the ratio of two quantities, one being the sound level that is measured and the other being a reference sound level corresponding approximately to the faintest sounds detectable by the human ear. The greater the sound level measured in dB, the louder is the sound. Generally, a change of 2dB is just perceptible, 5dB is clearly audible, and 10dB appears twice as loud.
