In this paper, the use of a Wireless Acoustic Sensor Network (WASN) for the estimation and equalization of room acoustics is proposed as a flexible and promising alternative to the traditional wired implementations. The authors consider a multiple-point equalization problem based on a Common-Acoustical-Pole (CAP) room model. Instead of collecting microphone signals in a central processing unit to compute the CAP model estimate in a centralized fashion, they deploy a large number of autonomous nodes with local sensing, processing, and communication capabilities to solve the CAP model estimation problem in a distributed manner.
