Sabine’s five questions framed the whole research program of architectural acoustics

Evidence

Sabine’s questions included the following: 1. What are the quantifiable aspects of sound in confined spaces that are important for listening? 2. Is a room that is thought to be excellent for speech likely to be excellent for music, and vice versa? 3. How do size, shape, and materials used for construction affect the listening quality and quantifiable aspects of sound in a room? 4. When sound dies down in a room, does it die down at the same rate in different places, and does it depend on the position and type of the original source of sound? 5. Does everyone in a room hear the same thing no matter where they are sitting? If not, what differs from place to place? Only loudness, or could the spectral content also differ? What makes some seats supposedly better than others in concert halls? — Eric J. Heller, Why You Hear What You Hear- An…, 2449
