Final answer:
The positioning of a source in playback, giving a percentage of information to each speaker, is known as sound localization or panning. In terms of sound intensity, the inverse square law is used to calculate the intensity at a specific distance from a speaker. Understanding sound localization and the inverse square law can help determine the sound distribution and intensity in a stereo system.
Step-by-step explanation:
The positioning of a source in playback, giving a percentage of information to each speaker, is known as sound localization or panning. In stereo sound systems, sound engineers use a technique called pan-pot to assign specific percentages of sound to each speaker. For example, if a sound is panned 100% to the left speaker, it means that all of the sound is going to the left speaker and none to the right speaker.
In terms of sound intensity at a specific distance from a speaker, we can use the inverse square law to calculate it. The inverse square law states that the intensity of sound decreases proportionally to the square of the distance from the source. To find the distance at which the intensity is 0.1 W/m², we can rearrange the formula and solve for the distance.
Using the given information in the question, the surface area of the speaker is 0.05 m² and it produces 1W of acoustical power. To find the intensity at the speaker, we can divide the power by the surface area. To find the distance at which the intensity is 0.1 W/m², we can plug in the values into the inverse square law and solve for the distance.
