You can't say anything about them unless their frequencies are the same.

In that case, you've already said that they're in phase, so their interference

is constructive. The resultant sound is louder than either wave alone. If their

amplitudes also happen to be the same, then the resultant sound is double

the intensity of either one alone (6 dB louder).
