Question about microphone sound

  • #1

Homework Statement



One microphone is located at the origin, and a second microphone is located on the +y axis. The microphones are separated by a distance of D=1.5 m. A source of sound is located on the +x axis, its distances from microphones 1 and 2 being L1 and L2, respectively. The speed of sound is 343 m/s. The sound reaches microphone 1 first, and then .00146 s later, microphone 2. Find the distances L1 and L2


Homework Equations





The Attempt at a Solution



L1= x
L2= x + (343 * .00146)

1.5^2 + X^2 = (x+ (343*.00146))^2
x= 1.996

L1=1.996
L2=2.4968
