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 of your upper limit displayed in the leading for sound localization and the 670 hits for sound lateralization were investigated. After inspection from the URLs, it was located 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 review. The screening procedure and the quantity of resulting hits are shown in Figure 1. As a Cefapirin sodium Protocol result, nine scientific articles for the overview of sound localization and 5 for sound lateralization were picked up. The five articles for sound lateralization, nonetheless, were the same as the nine articles for localization, so these nine articles had been selected. Furthermore, the nine articles for sound localization were categorized into those with normal-hearing participants with bilateral simulated CHL (3 articles: Table 1) and these with bilateral CHL (six articles: Table two).Audiol.
