Constructive Interference
This is called interference. Positive interference makes bigger waves, Negative interference makes smaller waves.
No. Waves that are out of phase (negative interference) will essentially cancel each other out. Waves that are in phase with each other (positive interference) will combine to create a larger wave.

This is known as 'Sound Cancellation' or deconstructive interference. It occurs when two waves 180º out of phase of and of equal magnitude combine. The resulting wave has zero magnitude and thus cannot be heard.
It is called the interference of the two waves.

Constructive Interference is when waves allign or "in phase" meaning wave peaks and troughs match. The amplitude of the two waves adds up, creating a bigger combined amplitude.Destructive interference is when waves are "out of phase." The amplitudes along the meeting points of the two waves combine, having a negative effect. If the amplitudes are exactly equal and opposite, the waves will cancel each other out.
A bigger amplitude. If the interference is perfectly constructive (same frequencies, in phase), the resulting amplitude will equal the sum of the two wave amplitudes.
