Answer: Cues that require two ears are referred to as binaural cues.
Step-by-step explanation:
This type of cue provides the ears the location of sound that travels the horizontal axis that relies on vibration. This connects the two eardrums to hear the sound being given.
The brain itself uses several cues to determine the location of any given sound. If a person can only hear out of one ear, this is called unilateral hearing loss. When a person can't use both ears they may use a hearing aid which will help the brain get the binaural and other cues so the person can hear in both ears.
