Architectural/Interiors Factors influencing sound propagation indoors include the physical dimensions and geometry of the space as well as the absorptive, reflective or diffuse characteristics of the terminating surfaces (walls, floors and ceilings). Overall sound level intensity and quality within the space are defined by acoustic phenomena such as reverberation, echoes, sound concentrations and room resonance. Depending on the use of the space, the sound quality varies with the reverberation time |
(RT60) in seconds. This is the time it takes for a sound to decay 60 dB. “Dead spaces” have low reverberation times and are ideal where speech intelligibility is the top priority. Higher reverberation times characterize “live spaces” that are best for performance areas dedicated to music. Reverberation times in-between are best suited for multi-purpose spaces where both speech and music are important. Reverberation times over 3 seconds should be avoided altogether |
