Because when you open your mouth and the ear comes in as negative pressure; the ostacious tube which is a canal connecting middle ear to the pharynx is increase in pressure by air; then pushes the ear drum to out side (slightly) so the sensitivity to sound waves decreases, that is why sometimes we cant hear the sounds while we are yawning.
