Course content:
1. Time-Space perspective: Sound propagation in a room
Raytracing, example of a rectangular room, evolution from free field to diffuse field, initial time delay gap (ITDG), direct sound, first reflections, late reverberation, exponential decay of the pressure, definition of the reverberation time, T60, T30, T20, Schroeder curve, critical distance, flutter echoes, diffusion, effect of distance, effect of room size
2. Frequency-Space perspective: Room modes
Reminder: monodimensional standing waves, axial modes, tangential modes, oblique modes, eigenfrequencies, effect of room size on modal density, duration and bandwidth of modes, effect of absorption on modes, Schroeder Frequency
3. Time-Frequency perspective
Early reflections, modes and diffuse reverberation in an unified time-frequency perspective, waterfall view
4. Room acoustics design
prediction of the reverberation time, Sabine formula, frequency-dependent absorption, porous absorbers, effect of absorber’s thickness and air gap, resonant absorbers, membrane absorbers, Helmholtz absorbers
5. Room acoustics of listening rooms
importance of symmetry, need for a sufficient room size and controlled reverberation time, recommended reverberation time, need for controlling the early reflections, LEDE design, RFZ design
6. Spatial hearing in a room
perception of distance in a room, perception of the room size, clarity, apparent source width, envelopment, reverberation timbre
