 The sound-as-sensations theory is justified by some facts about auditory experience. People report hearing voices and bells even when no one is speaking and no bell is ringing. Various examples of subjective sounds are documented under the label of tinnitus. In an anechoic chamber, most subjects experience subjective buzzing and whistlings. Some subjects undergo pathologic tinnitus when they hear sounds that disrupt their normal auditory capabilities. When Russian composer Shostacovich turned his head on a side, he was subject to a flow of melodies (Sacks 2008). Tinnitus and other subjective auditory phenomena have different causes, that can be related to the mechanical properties of the inner ear or to more central features. The objects of these experiences are naturally and spontaneously categorized as sounds. If sounds are simply defined as the objects of audition, then they are easily identified with the qualitative aspects of auditory perception. Various strands of indirect realism in perception would make this view mandatory. According to them, it is by hearing the immediate, proximal items that we hear some distal events or objects. In such a case sounds would be defined as the immediate objects of auditory perception.
