Question

A decibel is a logarithmic unit that can be used to measure the intensity of a sound. The function

Answer 1

Y = 10logx

"The sound intensity of rustling leaves is 100 times the reference intensity."
but x = ratio of intensity of sound to reference to intensity, so the x = 100:1 or x = 100

y = 10log(100) = 10 * 2 = 20 decibels


20 decibels

Answer 2

X=100
Y=10log100
Log100= 2
2x10=20
Y=20 decibels
