Auditory display apparatus and auditory display method

摘要

An auditory display apparatus is provided that places sounds such that sounds whose fundamental frequencies are close to each other are not adjacent to each other. A sound transmission/reception section receives sound data. A sound analysis section analyzes the sound data, and calculates a fundamental frequency of the sound data. A sound placement section compares the fundamental frequency of the sound data with a fundamental frequency of adjacent sound data, and places the sound data such that a difference in fundamental frequency is maximized. A sound management section manages a placement position of the sound data. A sound mixing section mixes the sound data with the adjacent sound data. A sound output section outputs the sound data obtained by the mixture to a sound output device.
