What Is the Decibel Range for a Normal Human Speaking Voice?

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. A decibel is also known as the ability of the human ear to note changes in sound intensity. The decibel unit is measured in powers of 10 for manageability, and a subtle difference of just 1 dB is enough for the human ear to make a distinction.
