Removing the monaural spectral cues tended to increase the horizontal localization acuity (11.31°). Marmosets have larger horizontal MAA (15.54°) in the rear than the front.

Chapter 12: Sound Localization and the Auditory Scene

WebSound localization is the ability to predict the position of a sound source and is based on the processing of auditory localization cues such as binaural or monaural cues (e.g. Akeroyd, 2014; Middlebrooks, 2015).

WebSound source localization is paramount for comfort of life, determining the position of a sound source in 3 dimensions: azimuth, height and distance. It is based on 3 types of cue: 2 binaural (interaural time difference and interaural level difference) and 1 monaural spectral cue (head-related transfer function).

WebMonaural cues depend upon the direction of sounds with respect to the head and the external ear, and contribute primarily to front-back disambiguation, elevation estimation, and distance perception of sounds. They can be successfully extracted only from high-frequency sounds (>4000 Hz Middlebrooks, 2015 ).
