Can multiple exact same sounds played over each other produce a louder decibel output than the original sound?

This is an example of constructive or destructive interference. If the waves are in-phase, this is constructive interference. The intensities of the two waves will add up and create one much more intense wave.

If the two waves are out of phase, then destructive interference will be experienced. If we have destructive interference, the waves will create a lower intensity wave, but as mentioned before, it depends on where the sound is measured because it will be louder in some places, and much quieter in others.
