Sounds

This frame is concerned with the percepts that vibrations which travel through the air or another medium produce in hearing organs. Sounds are a subtype of sensation. In talking about sounds, speakers often provide information about how the sound was produced. A Noisy_event may be mentioned which gives rise to the sound. Alternatively, the sound may be attributed to a Sound_source, which is construed as a point source emitting the sound. A further possible specification of what gives rise to the sound is for speakers to talk about two physical entities coming into contact by motion, resulting in either friction or impact.
