Traditionally, the presentation of data to users has always been focused on visual media. However, human beings live and interact in a world full of different sounds. From ecological sounds that characterize our environment to voice, which is the basic element of man-man communication, sound provides valuable information to humans on the environment. However, despite its importance, auditory information is still underused in human-machine interfaces.  The acoustic characterization of application environments, as well as the development of new auditory displays and sound-based interaction methods is also an active research field in acoustic technology.
