How does interference affect sound waves?

Hint : Acoustic wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or the other liquid or solid matter) because it gets away from the sound object. The source is a few objects that cause a vibration, like a ringing telephone, or an individual's vocal chords.

Complete Step By Step Answer:
When two or more sound waves occupy an equivalent space, they affect each other. The waves don't bounce off of every, but they move through one another. Two identical sound waves can add constructively or destructively to offer different results.
When two waves of comparable frequencies interfere, the results a beat frequency. A beat frequency may be a pulsing sound that goes up and down in loudness. Because the two waves enter and out of phase, the varying constructive and destructive interference makes the wave grow and shrink in amplitude.
Wave interference is that phenomenon that happens when two waves meet while traveling along an equivalent medium. The interference of waves causes the medium to require a shape which ends up from the internet effect of the 2 individual waves upon the particles of the medium.

Note :
This is often called constructive interference. If the 2 amplitudes have opposite signs, they're going to subtract to make a combined wave with lower amplitude. Constructive interference will make a sound louder while destructive interference will make a sound quieter.
