Speaker A is moved away from the listener while speaker B remains at the initial location. In the "later" situation, the speaker A is moved to the left of speaker B by a distance labeled "d". Part D - In the "later" situation, what is |d1 - d2|? Note: The distance from speaker A to the listener is denoted as d1. The distance from speaker B to the listener is denoted as d2. "later" |d1 - d2| = L- d |d1 - d2| = L |d1 - d2| = d -L |d1 - d2| = L/2 |d1 - d2| = d/2 |d1 - d2| = d +L |d1 - d2| = d
