Acousticians give a lot of meaning to the acoustic volume of a space. Too large and the room can be too reverberant, not loud enough and the early reflections are inaudible. Too small and the room cannot develop enough reverberation and uncomfortably loud.
Get it wrong and the space will have a lifelong handicap. It is not easy to reduce volume, nor is it cheap to increase it later on. So checking the acoustic volume is one of the critical tasks one repeats throughout the design process.
