Sound‐pressure response measurement in small rooms over a finite region

Microphone measurement of sound‐pressure response in rooms can give signals that are specific to the position at which it is taken. A measurement responsive to a region about the measurement position can easily be gained by taking several pressure readings. The challenge is to obtain such an average while limiting the number of measurement positions. The advantages of such a measurement are given. The problem is defined 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 show good estimates of the averaged response.
