Textbook Problem

A person standing 1.00 m from a portable speaker hears its sound at an intensity of 7.50 × 10−3 W/m2. (a) Find the corresponding decibel level. (b) Find the sound intensity at a distance of 35.0 m, assuming the sound propagates as a spherical wave. (c) Find the decibel level at a distance of 35.0 m.

(a)

To determine
The intensity level corresponding to an intensity of 750×103W/m2 .

Explanation

Given Info: The intensity of sound is 750×103W/m2 and reference intensity is 1.0×1012W/m2

Formula for intensity level of a sound,

β=10log(II0)

  • I0 is the reference intensity.
  • I is the intensity of a sound.

Substitute 750×103W/m2 for I and 1

(b)

To determine
Sound intensity at a distance of 35m.

(C)

To determine
The sound intensity level at a distance of 35 m.
