Asound is recorded at 19 decibels. what is the intensity of the sound?

79·433 × W/m²

Explanation:

Given intensity of sound in decibels is 19

Formula for intensity of sound in decibels is

where

is the intensity of sound measured in decibels

I is the intensity of sound measured in W/m²

is the intensity of the sound that is taken as standard and it's value is equal to W/m²

By applying the formula

19 = 10 × ㏒(I ÷ )

⇒ 1·9 = ㏒(I ÷ )

⇒ antilog(1·9) = I ÷

⇒ 79·433 = I ÷

⇒ I = 79·433 × W/m²

∴ Intensity of sound = 79·433 × W/m²
