Xclude “Include patents” and “Include quotes”. The search resulted in 1079 hits for sound localization and 670 hits for sound lateralization. These contents had been sorted in descending order of relevance. The 1000 hits of the upper limit displayed from the top rated for sound localization plus the 670 hits for sound lateralization had been investigated. Soon after inspection with the URLs, it was discovered that 982 hits for sound localization and 653 hits for sound lateralization had been valid for analysis, immediately 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 review. The screening course of action and also the number of resulting hits are shown in Figure 1. Consequently, nine scientific articles for the evaluation of sound localization and 5 for sound lateralization had been picked up. The 5 articles for sound lateralization, on the other hand, were the same because the nine articles for localization, so these nine articles had been chosen. Furthermore, the nine articles for sound localization have been categorized into those with normal-hearing participants with bilateral simulated CHL (3 articles: Table 1) and those with bilateral CHL (six articles: Table 2).Audiol.
