A method for assisting a user in selecting audible alarm settings of a patient monitoring system for monitoring a patient is provided. A synthesis model is generated in response to 1) data indicative of audio features derived from audio recorded in the patient room, and 2) data indicative of vital signs recorded from the patient monitoring system. Sets of audio parameters indicative of respective plurality of audible alarm settings are then processed according to the synthesis model so as to generate respective outputs, e.g. indicative of audibility of the plurality of alarm sounds according to the audible alarm settings synthesized to be played in or outside the patient room. These outputs can then be presented to a user, so as to allow the user to evaluate e.g. alarm audibility and noise level impact of the plurality of audible alarm settings, and e.g. adjust the settings accordingly, such as alarm thresholds etc. The synthesis model may comprise an auralization module, so as to generate synthesized audio outputs to the user. The synthesis model may take into account actual room acoustics in or outside the patient room, so as to allow a precise calculation and/or audio synthesis of an alarm sound to be played in the environment. Alternatively, or additionally, the systhesis model can generate objective and/or subjective metrics that allows the user to find a suitable balance between alarm audibility and impact on noise level. |
