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 from the upper limit displayed from the major for sound localization and also the 670 hits for sound lateralization were investigated. Right after inspection from the URLs, it was located that 982 hits for sound localization and 653 hits for sound lateralization were valid for analysis, after excluding links that displayed a “Not found” or “Not connected” message. These hit numbers had been set because the initial values for screening for this critique. The screening method along with the variety of resulting hits are shown in Figure 1. Because of this, nine scientific articles for the review of sound localization and five for sound lateralization have been picked up. The five articles for sound lateralization, on the other hand, had been exactly the same because the nine articles for localization, so these nine articles have been selected. Additionally, the nine articles for sound localization were categorized into those with normal-hearing participants with bilateral simulated CHL (three articles: Table 1) and these with bilateral CHL (six articles: Table 2).Audiol.
