Abstract
This study is to understand the shortcomings of the metaverse space and apply realism to implement it. Embodying spatial realism in various ways has been using methods that have been studied by focusing on the funeral of familiar encounters. The purpose of this study is to understand these acoustic elements because the understanding of the ambient sound in this problem was not considered. This study applied and used acoustic ambient sound as a method to maximize this realism and maintain realism by considering the user's environmental part. In addition, in this sense of realism, the weight of the surrounding noise is applied, and the signal-to-noise values of the users are applied. An efficient acoustic adaptation approach is applied to the weight between users as the signal-to-noise ratio. These acoustic considerations can be applied in a variety of ways.

Keywords
Improved metaverse, Spatial sound, Signal-to-noise ratio, and Sound quality.
