In order to study the influence of the voting fusion regulation on detection efficiency of acoustic sensor network,
sensor field is discretized into multiple grids, and two metrics are defined to evaluate the detection capability of the sensor
network. Calculation methods for the metrics are given with theorem descriptions. Simulations indicate that the proposed
metrics can evaluate the detection efficiency of the system in a quantitative style, and they can provide theoretic evidence for
the parameter selection of the detection regulation and the optimization of the sensor deployment scheme.
