Suppose you work for a company that makes isotropic sound sources, such as the one shown in the photograph in Fig. 17.10.1. The source produces sound waves with average power of 100 W. Interactive Figure 17.10.1: The speaker at the top of the vertical pole emits sound waves uniformly in all directions. Such a source is said to produce isotropic sound waves. This particular speaker is made by the Italian company Outline. (Source: Outline Audio.) A small detector (a microphone) is located at a point D that is distance 4.00 m from the source. What is the intensity of the sound wave at the location of the detector? I = = W/m What power is incident on the detector at D due to the sound waves if the detector has area 0.100 m? Pdetector i W Pnew = Mi If the same detector is moved closer such that the distance from the source is halved, by what factor does the power incident on the detector increase? Pold
