 Consider an analogy with light. In the realm of vision, the closest analogue to sounds are the activities of light sources. We perceive these activities, and we perceive them as located where their sources are: the emission of a light bulb out there, the glowing of candlelight over the table, the irradiation of the sun at the horizon; each with its own respective color. Do we perceive light itself, as opposed to the events of light emission at light sources? Clearly, light travels from the source to our eye—if it didn’t, we would not perceive the source. But what we perceive is the emission event, and not the light. An irrelevant element of disanalogy is related to the temporal unfolding of sounds and light events respectively. Typically in the environment light is emitted continuously, whereas sounds occur episodically and have short lives. If most light sources were intermittent as in piezoelectric lighters, or if most objects were buzzing all the time, this element of disanalogy would be less salient (Pasnau 2007).
