Constructive
When waves act together, you talk about "interference".When they reinforce each other, it is "constructive interference".When they cancel each other, it is "destructive interference".
constructive or destructive interference
An echo is just the reflection of sound from a surface. As such it is neither constructive or destructive. These terms refer to the way sound waves combine with each other.
Interference. Constructive Interference, which is where the waves increase amplitudes and troughs when they overlap. Destructive Interference, which is where the waves cancel each other out when they overlap.
Interfere with each other. This interference can be either constructive or destructive.

constructive or destructive interference
There will be either constructive or destructive interference.

If a pulse "interferes" with another pulse, they build each other up to form supercrests or supertroughs. This process is known as constructive interference.
Interference. This can result in either constructive interference, resulting in increased amplitude, or destructive interference, whereby there would a reduced amplitude.

well think about it... if they cancel each other out, are they constructive or destructive?
when two waves superimposed on each other in the same phase (phase diff is 0), then the resultant amplitude becomes the sum of the amplitudes of the two waves. This type of interference is called constructive interference. on the other hand, when two waves superimposed on each other in the opposit phase (phase diff is 180 degree), then the resultant amplitude becomes the difference of the amplitudes of the two waves. This type of interference is called destructive interference.
Destructive interference is where two sound waves mix and cancel each other out to some extent. If destructive interference is occurring, the sound level will be lower than you would otherwise expect. A properly designed auditorium will use both destructive and constructive interference where required to achieve the desired clarity of sound.
