Abstract
A plurality of sound sensors is disposed in a space of interest. Each sensor comprises a light-emitting output. Each sensor can be positioned at a specific location, such as at an ear location for a seated listener. An excitation source can provide a specified acoustical energy stimulus to the space. A user can obtain a visual impression of acoustical response of the space corresponding to the sound sensors' positions. An image acquisition system can acquire an image of the sound sensors responding to a stimulus. Acquired images can be analyzed to determine response characteristics. A presentation system can provide a display of response characteristics.
Claims26
A system for characterizing acoustical response of a space comprising:
- an excitation source;
- a first sensor module adapted to provide a first light output responsive to the excitation source,
- wherein the first sensor module is disposed at a first position within the space,
- wherein the first sensor module emits the first light output at essentially the first position;
- and,
- a second sensor module adapted to provide a second light output responsive to the excitation source,
- wherein the second sensor module is disposed at a second position within the space,
- wherein the second sensor module emits the second light output at essentially the second position.
