Sound localization refers to a listener's ability to identify the location or origin of a detected sound in direction and distance. It may also refer to the methods in acoustical engineering to simulate the placement of an auditory cue in a virtual 3D space (see binaural recording, wave field synthesis).
While sound will readily travel through many materials, in order for us to hear it, it will have to travel through the air to reach our ears (eardrum). Your eardrum vibrates from sound waves to allow you to sense them. We might be able to detect it through vibration of solids, the ripple in liquid but you can only detect it in air by hearing it. In spite of this, humans cannot hear all sounds that travel through the air. It will have to be at a certain decibel for us to hear it. For e.g. dogs can hear sounds that are not able to be detected by humans. Sound can also be detected by other means other than hearing it.
