Abstract

A localized sound projection system can coordinate the sounds of speakers to simulate the placement of an auditory cue in a 3D space. The system can include a plurality of speakers configured to output auditory signals and a sound localization controller configured to control the plurality of speakers to coordinate the auditory signals to simulate an origination location of a patient alarm. The sound localization controller can determine adjusted auditory signals and control a plurality of speakers to output the plurality of adjusted auditory signals. A method for dynamically controlling speaker settings in a medical environment can include determining volume settings corresponding to a speaker, monitoring a level of ambient noise corresponding to a room of a patient, controlling the volume settings of the speaker to reduce or increase a sound level output of a speaker. A patient monitoring system can be configured to physically manipulate medical devices in response to audible commands. The system can receive a plurality of vocal commands from a user and can manipulate various settings after confirmation from a user.

Claims

1. A patient monitoring device, comprising:

a plurality of speakers configured to output auditory signals;

a noise sensor; and

an acoustics controller comprising a processor configured to;

control the plurality of speakers to output one or more test auditory signals,

receive noise data from the noise sensor corresponding to the one or more test auditory signals,

determine acoustics of a surrounding environment based at least in part on the received noise data, and

adjust one or more speaker parameters of the plurality of speakers based on the determined acoustics.

2. The device of claim 1, wherein the adjustment of the one or more speaker parameters optimizes the output auditory signals for the determined acoustics of the surrounding environment.

3. The device of claim 1, wherein the plurality of speakers comprises a first speaker and a second speaker.

4. A system for providing localized projection of audible noises, the system comprising:

a plurality of speakers configured to output auditory signals; and

a sound localization controller configured to control the plurality of speakers to coordinate the auditory signals to simulate an origination location of a patient indicator, wherein the sound localization controller comprises a processor configured to;

receive an indication of an activation of the patient indicator,

determine the origination location of the patient indicator based at least in part on the indication of the activation of the patient indicator,

based at least in part on the origination location, identify sound parameters for each of the plurality of speakers, wherein the sound parameters corresponds to at least one of a timing, intensity, or frequency of a sound signal,

determine adjusted auditory signals based at least in part on the identified sound parameters,

control the plurality of speakers to output the plurality of adjusted auditory signals.

5. The system of claim 4, further comprising a patient monitoring device configured to:

receive one or more patient signals from one or more physiological sensors;

determine measurements of physiological parameters of a patient from the received one or more patient signals;

monitor alarm criteria associated with the one or more measurements of the one or more physiological parameters; and

transmit the indication of the activation of the patient indicator.

6. The system of claim 4, wherein the origination location comprises at least one of a physiological sensor, a patient monitoring device, a patient, a patient room, or one of the plurality of speakers.

7. The system of claim 4, wherein the adjusted auditory signals comprises at least one alarm signal and at least one time-delayed alarm signal.

8. The system of claim 4, wherein plurality of speakers comprises a first speaker and a second speaker, wherein the first speaker is located closer to the origination location than the second speaker, and wherein the first speaker is configured to output the at least one alarm signal and the second speaker is configured to output the at least one time-delayed alarm signal.

9. The system of claim 8, wherein the at least one time-delayed alarm signal is a time-delayed copy of the alarm signal.

10. The system of claim 8, wherein the at least one time-delayed alarm signal is time-delayed from the alarm signal by two milliseconds.

11. The system of claim 4, wherein the plurality of speakers are located in a patient room.

12. The system of claim 4, wherein the plurality of speakers are located in a nurses'"'"' station.

13. The system of claim 4, wherein the alarm signal comprises a heartbeat signal.

14. A method for dynamically controlling speaker settings in a medical environment, the method comprising:

determining a volume corresponding to a speaker of an electrical device;

monitoring, using a noise sensor, a level of ambient noise;

based on a determination that the volume of the speaker does not satisfy the volume threshold, adjusting the volume of the speaker.

15. The method of claim 14, further comprising:

determining, based on the level of ambient noise, that at least one of the patient, the room of the patient, or the speaker is located in a quiet zone of a hospital; and

determining the volume threshold based at least in part on the determination that the at least one of the patient, the room of the patient, or the speaker is located in a quiet zone of a hospital, wherein adjusting the volume of the speaker comprises reducing the volume of the speaker.

16. The method of claim 14, further comprising:

determining the volume threshold based at least in part on the time of day, wherein the time of day corresponds to nighttime, wherein adjusting the volume of the speaker comprises reducing the volume of the speaker.

17. The method of claim 14, further comprising:

determining, based on the level of ambient noise, that at least one of the patient, the room of the patient, or the speaker is not located in a quiet zone of a hospital; and

determining the volume threshold based at least in part on the determination that the at least one of the patient, the room of the patient, or the speaker is not located in a quiet zone of a hospital, wherein adjusting the volume of the speaker comprises increasing the volume of the speaker.

18. The method of claim 14, further comprising:

determining the volume threshold based at least in part on the time of day, wherein the time of day corresponds to daytime, wherein adjusting the volume of the speaker comprises increasing the volume of the speaker.

20. The method of claim 18, further comprising:

receiving a third vocal command;

failing to interpret the third vocal command; and

controlling the speaker to provide an audible indication that the third vocal command was not interpreted.

19. A method of audibly altering parameters of a medical device, the method comprising:

receiving, using a microphone, a first vocal command;

interpreting the first vocal command as an activation phrase configured to initiate a process of audibly altering parameters of a medical device;

controlling a speaker to provide an audible indication of an acknowledgment of the activation phrase and initiation of the process of audibly altering parameters of the medical device;

after controlling the speaker to provide the audible indication, receiving, using the microphone, a second vocal command;

interpreting the second vocal command as a request to alter the parameters of the medical device;

causing a display to display, in text, an indication of the interpreted request to alter the parameters, wherein the indication includes a request for confirmation;

receiving the confirmation; and

altering the parameters of the medical device.
