These applications exploit the capability of Binaural Technology to archive the sound field in a perceptually authentic way, and to make it available for listening at will, e.g., in entertainment, education, instruction, scientific research, documentation, surveillance, and telemonitoring. It should be noted here that binaural recordings can be compared in direct sequence (e.g., by A/B comparison), which is often impossible for the original sound situations. Since the sound-pressure signals at the two ear-drums are the physiologically adequate input to the auditory system, they are considered the basis for auditory-adequate measurement and evaluation, both in a physical and/or auditory way [31]. Consequently, we have the further application category discussed below.
