Paper	Main Results
Bauer et al. [61]; Florentine [62]; Musicant and Butler [63]; Slattery and Middlebrooks [64]; Kumpik et al. [65].	Low initial sound localization accuracy, but significant improvements after a period of several days.
Held [66]	Displacement of auditory representation halfway in the direction of the sound source’s azimuth shift. Localization accuracy improved after a few days.
Hofman et al. [67]; Carlile and Blackman [68]	Immediately after mold insertion, localization was severely impaired, but after several days performance improved gradually, reaching pre-training accuracy levels when the molds were removed.
Carlile [69]; Zahorik et al. [70]; Strelnikov et al. [71].	Improvements in sound localization, especially decreased front-back confusion.
Honda et al. [72].	Decreases in sound localization errors in the horizontal and in the vertical plane, regardless of head movement
Bălan et al. [73]	Decreases in sound localization error and front-back confusion rate for broadband and narrowband sounds.
Parseihian and Katz [74]	Reduced angular precision errors and front-back confusion
Mendonça et al. [75]	Sound localization performance improved for all participants
