1. An alarm detection and validation device for validating acoustic alarms that have been generated by a medical device, the alarm detection and validation device comprising:

  • a microphone arranged to output a first signal corresponding to audio detected by the microphone;

    anda processing unit arranged to;

    receive the first signal from the microphone;

    receive a second signal from the medical device indicating that the medical device has generated an acoustic alarm;

    analyze the first signal to determine whether the detected audio includes the acoustic alarm generated by the medical device by applying a sound classifier to the detected audio so as to identify known alarm sounds included in the detected audio; and

    output a third signal to the medical device based on the result of the analysis of the first signal, if the result of the determination is that the detected audio includes the acoustic alarm generated by the medical device, wherein the third signal comprises an instruction that the medical device alter one or more parameters of the acoustic alarm, wherein the one or more parameters include at least one of alarm volume, alarm pattern, alarm spectral composition, and which loudspeaker is used to emit the alarm.
