In every day life, the sound that arrives at our ears is a cacophonous mixture of the sound source and reflections by nearby objects. Anecdotally reflections were claimed to provide critical information about the environment. However, when listening in small rooms these reflections normally fall into a ‘fusion’ interval whereby the auditory system...
