It is indeed possible

Explanation:

If two sound waves of equal intensities and wavelength interfere with a path difference(#Deltax#) equal to #(2n-1)(lambda)/2# or phase difference(#Deltaphi#) equal to #(2n-1)pi# where #lambda# is wavelength and #n=1,2,3,4....# then the resultant intensity will be zero and hence the waves cancel each other out.
