Quick Answer. The decibel range for a normal human speaking voice is around 70 dB. When a person is talking in an elevated voice, the decibel range is around 76 dB. An individual who talks very loudly would have a decibel range of around 82 dB, while someone who shouts would reach levels of around 88 dB.
The loudness of sound is measured in units called decibels (dB). A decibel unit expresses the relative intensity of sounds on a scale from zero for the average least perceptible sound to about 100 dB, which is near the level most people find uncomfortably loud. Normal speech is around 50 to 60 dB. The following chart demonstrates the sound scale in decibels. When an individual is over-exposed to excessive loudness, sensitive structures of the inner ear, such as hair cells, can be damaged, causing noise-induced hearing loss (NIHL), a particular type of hearing loss.
