Hearing ultrasonic but only in 1 ear ?

[freedom]

Hi, at notmal frequencies I can hear fine with both ears but with the ultrasonic tracks,
I can only hear it with my right ear and not my left. Just wondering, is this normal ?? Hope this isn't a sign of hearing loss or something Im just a young 22 year old dude. Oh yeah, and I would also like to know if not hearing the ultrasonic in my left ear would affect its effectivness ?

Are you sure your speakers/earphones are not damaged?

No I can hear both sides clearly with the masked tracks but not ultrasonic. With ultrasonic I can hear the screeching sound from both sides with my right ear but not with my left
