Line 13:
A high strength of low frequencies and incoherence of the left and the right ear of one auditory stream, especially of its direct sound and early reflections, increase the apparent source width.<ref name=blau/><ref name=ziemer/><ref name=beranek/>
Even in absence of room acoustical reflections the pure direct sound of musical instruments already effects the perceived source extent.<ref name="ziemer">{{cite book|last1=Ziemer|first1=Tim|editor1-last=Schneider|editor1-first=Albrecht|title=Studies in Musical Acoustics and Psychoacoustics|volume=4|doi=10.1007/978-3-319-47292-8_10|date=2017|publisher=Springer|___location=Cham|isbn=978-3-319-47292-8|pages=299–340|chapter=Source Width in Music Production.
