1. A device comprising:
a movable platform configured to support an infant inside the device;
a sound output device configured to provide a sound for soothing the infant;
a sensor system comprising a plurality of microphones disposed proximate to the movable platform operable to detect a noise, wherein the sensor system is configured to generate measurement data for the noise detected; and
a control system communicatively connected to the sensor system, the control system being configured to receive the measurement data generated by the sensor system and to determine, based at least on a location of the noise detected as determined by applying a directional filter to the measurement data, whether the noise detected originates from inside or outside the device;
wherein, if the noise detected is determined to originate from inside the device, the control system is further configured to apply a frequency filter to the measurement data to determine whether the noise detected comprises an infant cry;
wherein, if the noise detected is determined to comprise the infant cry, the control system is further configured to apply a threshold filter to the measurement data to determine a state of infant cry; and
wherein the control system is further configured to provide, based on the state of infant cry, a control signal to operate at least one of the movable platform or the sound output device to soothe the infant.
