SOUND-PRESSURE RESPONSE MEASUREMENT IN SMALL ROOMS OVER A FINITE REGION

Microphone measurement of sound-pressure response in rooms can give si gnals that are specific to the position at which it is taken. A measur ement responsive to a region about the measurement position can easily be gained by taking several pressure readings. The challenge is to ob tain such an average while limiting the number of measurement position s. The advantages of such a measurement are given. The problem is defi ned fully in terms of source and target signals. The use of theory as a relating medium between source and target is discussed and rejected. The use of neural networks is introduced as a relating medium capable of learning from example. Some provisional results are given which sh ow good estimates of the averaged response.
