1/10/2024 0 Comments In sound mind length![]() The intensity is 100 x (2.2 x 10 -4 W/m 2 ) or 2.2 x 10 -2 W/m 2 so the decibel rating is 103 dB. The intensity is 10 x (2.2 x 10 -4 W/m 2 ) or 2.2 x 10 -3 W/m 2 so the decibel rating is 93 dB. The intensity is 7 x (2.2 x 10 -4 W/m 2 ) or 1.54 x 10 -3 W/m 2 so the decibel rating is 92 dB. The intensity is 4 x (2.2 x 10 -4 W/m 2 ) or 8.8 x 10 -4 W/m 2 so the decibel rating is 89 dB.į. Using this equation, parts a - d can be computed in straightforward fashion.Ī. Where I = intensity of the sound in units of W/m 2. The equation which relates the intensity of a sound wave to its decibel level is: dB = 10 * log( I / 1.0 x 10 -12 W/m 2) The sound of an orchestra playing a movement fortissimo at 2.5 x 10 -4 W/m 2 (very loudly). ![]() The sound of an orchestra playing a movement pianissimo at 7.5 x 10 -6 W/m 2 (very softly).A sound which is 100 times more intense than the sound in part d.A sound which is 10 times more intense than the sound in part d.A sound which is 7 times more intense than the sound in part d.A sound which is 4 times more intense than the sound in part d.Determine the decibel rating of the following intensities of sound. Part C: Problem-Solving and Computational Problemsĥ3.
