Two identical loudspeakers are fed the same signal which generates sound of wavelength 8. The speakers are facing each A other, separated by a distance 48. At what minimum distance in front of a speaker, and on the line connecting them, is the local sound intensity a minimum? A) (714) 8 B) (4) 8 C)(/4)8 D) (/4) 8 5. Two identical loudspeakers (S1 and S2) are fed the same signal to generate sound of frequency / propagating at speed V. The speakers are positioned in line with a listener as shown. The speakers are separated by a distance X and speaker S2 is a distance L from the listener. What value of X results in a maximum sound intensity at the listener? A) 2fV/L B)fL/V C) 3V/f D) V/f SI B listener
