This study reviews previous studies on human echolocation in order to discuss known and possible uses of echolocation by human. Previous studies has been searched both manually and through web-based databases. Before studies on echolocation had conducted people believed that blind travellers uses the sixth sense which is \'facial vision\'. The studies on echolocation suggest that both blind and sighted humans were able to find obstacles by utilizing hearing perception. Further studies found that people are capable of substantial precision in the perception of properties of distal objects, such as distance, size, shape, and substance. This study suggests future research that focuses on sound types for efficient echolocating and experimental studies that can be implemented in the real world rather that experimental settings. Finally this current review discusses implications of research outcomes toward building centers, schools, and houses for people with visual impairments and planing of orientation and mobility programs.
