Two Source Interference Two sources of sound each creating sound waves. Two sources of sound each creating sound waves. Sound waves experience constructive and destructive interference creating loud spots and soft spots. Sound waves experience constructive and destructive interference creating loud spots and soft spots. Calculation only deals with the placement of the loud spots. Calculation only deals with the placement of the loud spots. Equation: Equation: Website Used In Class:
