Question

We are all familiar with the term "spaciousness" as describing a spatial quality. In designing a performance space for classical music, this word also describes an acoustic quality. Please define "spaciousness" as an acoustic quality and explain how it relates to spaciousness in the spatial sense.

Answer

Because our ears are on opposite sides of our heads, we receive sound signals slightly differently in each ear. This allows a listener to hear an acoustic quality called "spaciousness." Diffusion of sound in a performance hall can be enhanced by angled wall surfaces and protrusions that can enhance the acoustic experience of "spaciousness."
