Creating an Illusory Audio Experience

Some scientists want to go one step further and systematically manipulate the acoustic field to achieve an effect that shouldn’t exist per se, given the real-​life situation. For instance, they are attempting to create an illusory audio experience that tricks the listener into believing they are in a concrete building or an old church. Alternatively, objects can be made invisible by manipulating the acoustic field in such a way that the listener no longer perceives them.
