How sound defines space ?

how Aural architecture looks at sound as design?

: how sound defines space, creates realms of privacy or society, and produces a sense of place.

With environmental sound, LOUDNESS and the quality of REVERBERATION mainly determine the kind of space that is perceived, enclosed or open, large or small (see DIFFUSE SOUND FIELD,FREE FIELD). The sense of speeding motion is usually perceived by the presence of a DOPPLER EFFECT.

Buildings come to exist as sites of memory and imagination. Any built space, whether constructed for habitation or utility, resonates with the human activity that has occurred within it. Our experience of a space is influenced by many things; by knowledge of the functions of the space, by cultural associations, by memory and imagination. The way we experience a space is determined largely by our aural perception of that space. One can be in a room in complete darkness and yet still have a powerful sense of our own physical presence within it, through the sound of footfall, of the voice and even the sound of our our breath.
