Abstract:
Sound quality is judged by the realism of the auditory illusion, which is created in the listener’s mind, created from the sounds coming directly from the loudspeakers and by reflections and reverberations from the room, arriving from various directions and with different timings. The original sound streams from the musicians - performing in their acoustical environment - to the listener in his home have undergone significant changes in processing over the last 50 years, leading to dramatic improvements in dynamic range and bandwidth due to digital technology, but also to new forms of distortion. Electro-acoustic transducers have kept up with the developments. But loudspeakers built with those transducers have only marginally improved, especially when tasked to create a convincing aural scene, which takes the listener to the recording venue space in a typical size living room. The interactions between loudspeaker, room and hearing processes have not been sufficiently studied and premature conclusions have been drawn about loudspeaker design parameters. The typical loudspeaker comes with fundamental flaws, which critical listeners try to correct by room treatment. The solution would be a loudspeaker with spectrally neutral radiation in all directions. Such loudspeakers are extremely rare. In general, the quality of reproduced sound in the home has reached a plateau that is uninspiring to the Apple and Google generation.
