Xclude “Include patents” and “Include quotes”. The search resulted in 1079 hits for sound localization and 670 hits for sound lateralization. These contents have been sorted in descending order of relevance. The 1000 hits from the upper limit displayed from the best for sound localization and the 670 hits for sound Chlortetracycline Technical Information lateralization had been investigated. Just after inspection with the URLs, it was identified that 982 hits for sound localization and 653 hits for sound lateralization were valid for analysis, soon after excluding links that displayed a “Not found” or “Not connected” message. These hit numbers were set as the initial values for screening for this overview. The screening process and also the number of resulting hits are shown in Figure 1. Because of this, nine scientific articles for the evaluation of sound localization and 5 for sound lateralization have been picked up. The five articles for sound lateralization, having said that, were the same as the nine articles for localization, so these nine articles had been selected. Moreover, the nine articles for sound localization were categorized into these with normal-hearing participants with bilateral simulated CHL (3 articles: Table 1) and these with bilateral CHL (six articles: Table 2).Audiol.
