my car sings..!?!?!

[nisfive]

hi, im new here and i recently leased an 05 altima ser 6 speed. the car works fine, handles great and is very quick. although i do have a slight problem. everytime i cruise in fourth, fifth and sixth gear, i can hear a humming noice coming from the front or below towards the front on the driver side of the car....well, at least thats where i think its coming from. crazy thing about it, lets just say, is that if im in fifth gear cruising I can hear the hum but as soon as i let off the gas pedal completely, the humming goes away! then when i repress the gas pedal, the humming comes back! this all happens whether im in 4th, 5th or 6th, more noticeably when im in sixth gear cruising at 70 plus. what can possibly be causing this sound that gets annoying after awhile. thanks for anyones help.
