An environmental monitoring device that includes an acoustic sensor is described. During operation of the environmental monitoring device, the acoustic sensor provides acoustic data based on measurements of sound in an external environment that includes the environmental monitoring device. Based on the acoustic data and predefined characterization of the external environment, a control mechanism determines if an alarm device, which is separate from the environmental monitoring device, is activated. For example, the predefined characterization may include a location of the alarm device. This location may be specified by: an image of the external environment, a positioning system, a communication network, and/or an acoustic latency in the external environment. Alternatively, the predefined characterization may include an acoustic transfer function of the external environment proximate to the alarm device and the environmental monitoring device. Furthermore, if the alarm device is activated, the environmental monitoring device may provide an alert.
