**1. Homework Statement**

You are standing a distance d (1 m) in front of one of two identical speakers, being driven by the same source, that are a distance h (3 m) apart. You walk (starting at y=0) along a line parallel to the line of the two speakers. The speed of sound is 340 m/s and the frequency is 170 Hz.

Question: As you walk, how many times and where will you hear a maximum sound?

**2. Homework Equations**

ΔФ= 2λ/m + ΔФo

**3. The Attempt at a Solution**

I solved the above equation for the variables y and m, but I am unable to solve the equation to find what values of y where a maximum sound will be heard. My teacher suggested to make a plot of the path difference as a function of y using the given d and h and use the graph to determine the values of y which satisfy the maximum sound condition.
