its pretty much exactly the same engine as fallout new vagas, which isnt the same engine as oblivion. as far as i know... if you listen you will hear a lot of the fallout audio. but there is nothing in the game that is from oblivion as far as i know.
1 Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. 2  The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
The human ear has three distinct functional regions: the outer ear, which collects sound waves; the middle ear, which represents the sound waves as pressure, and the inner ear, which converts those pressure signals into electrical signals that the brain perceives as sound.
