Abstract: A method is provided that generates a sound illusion profile to replicate a quantity of resources arriving at an incident scene. A virtual partner or the like determines that an incident has escalated from a first severity level to a second severity level. The virtual partner determines a quantity of resources needed to deescalate the incident to the first severity level. A sound illusion profile is generated to replicate a sound associated with the quantity of resources. A signal is sent to one or more speaker devices in a region surrounding the location of the incident to generate an output sound based on the sound illusion profile.

Abstract: A device for clearing liquid from an audio transducer is provided. The device comprises an audio transducer and a port from an external surface of the device to the audio transducer. The device further comprises a liquid clearing mechanism for pushing liquid, trapped in the port, out of the port to clear a path for sound between the audio transducer and the external surface, and an actuator for operating the liquid clearing mechanism.
