In open spaces with free-field-like conditions, sound energy escapes into the atmosphere. The environment has little effect on the character of the sound. In enclosed spaces (i.e. rooms), sound energy is retained. A sound wave impacting on a room boundary will reflect back into the room. These reflections occur in their multitudes and dramatically affect the timbre of the sound. Furthermore, these reflections prolong the sound’s duration. For example, a hand clap in a very large reflective room will echo about the space.
In many situations it is desirable to control this reflected energy (reverberation). Too much reverberation will have the effect of reinforcing unwanted noises such as footsteps in a stairwell, or typing in an office space. Furthermore, speech becomes less intelligible in a room that is too reflective. The control of reverberation is also important for comfort. An excessively reflective room can feel cold. Productivity in a workplace can be reduced as a result of these effects.
Through the use of 3D models and computer simulations, iAcoustics can predict all acoustic parameters that relate to the behavior of sound in rooms. Such parameters can also be measured and verified through on-site testing. If it is established that reverberation control treatment is needed, suitable recommendations can be made.
