Well, obviously it works as a sensor jutsu. Thing is, it only goes up to mid range so it's more of an "incomplete" sensing jutsu, giving us a limited reading of our surroundings. Also, if the wave is interrupted, then our reading will be off. So since Sound in our RP can be treated almost as an off branch of wind, I'd say energy based attacks such as large widespread fire or wind jutsu would disrupt it, even pure chakra and Dark release. Er, since it's sound based (being a sound jutsu lol), if a loud enough sound occurs, we'd take more damage to our ears. Like if Deidara uses his C4 jutsu, we'd be more hurt from the sound even if it doesnt physically us. That's all I got. O_O
