a controller electrically coupled to the sound detecting sensor, the sound generating device, and the user interface, wherein when the controller receives an input from the user interface activating the sound conditioning system mode, the controller controls the operation of the sound generating device in accordance with the input from the sound detecting sensor to identify undesirable sound in the region of the person-support apparatus, generate a signal to cancel the undesirable sound, and simultaneously generate a separate masking sound.
2. The person-support apparatus of claim 1 , wherein the user interface further includes a sound masking mode where an undesirable sound is masked by a masking sound.
3. The person-support apparatus of claim 2 , wherein the masking sound is at least one of white noise and an environmental sound.
4. The person-support apparatus of claim 1 , wherein the user interface includes a display.
5. The person-support apparatus of claim 1 , wherein the user interface further includes an active sound controlling mode where an undesirable sound is sensed, the phase of the sensed signal is inverted, and the sound generating device outputs the inverted sensed signal to interfere with the undesirable sound.
6. The person-support apparatus of claim 1 , wherein the audible sound adjustment mode corresponds to a change in at least one of the volume of the sound output by the sound generating device and the tone of the sound output by the sound generating device.
7. The person-support apparatus of claim 1 , wherein the user interface is a pendant.
8. The person-support apparatus of claim 1 , wherein the user interface is coupled to a headwall unit.
9. The person-support apparatus of claim 1 , further comprising a siderail and an endboard coupled to the frame, the user interface being coupled to at least one of the siderail and the endboard.
10. The person-support apparatus of claim 1 , wherein the user interface is coupled to a mattress replacement system.
11. The person-support apparatus of claim 1 , wherein the controller is configured to control at least one other function of the person-support apparatus.
12. A person-support apparatus, comprising:
a frame;
a sound detecting sensor,
a sound generating device positionable on a person's head proximate the person's ears and configured to generate an audible signal;
a user interface configured to receive an input from a user; and
a controller operably coupled to the sound detecting sensor, the sound generating device, and the user interface, wherein when the controller receives an appropriate input from the user interface, the controller controls the operation of the sound generating device in accordance with an input from the sound detecting sensor to identify undesirable sound in the region of the person-support apparatus, generate a signal to cancel the undesirable sound, and simultaneously generate a separate masking sound.
13. The person-support apparatus of claim 12 , wherein the sound generating device is an earphone.
14. The person-support apparatus of claim 12 , further comprising a siderail and an endboard coupled to the frame, and wherein the sound generating device is a speaker coupled to at least one of the siderail and the endboard.
15. The person-support apparatus of claim 12 , further comprising a siderail and an endboard coupled to the frame, the user interface being coupled to at least one of the siderail and the endboard.
16. The person-support apparatus of claim 12 , wherein the user interface includes a display.
17. The person-support apparatus of claim 12 , wherein the controller is configured to control at least one other function of the person-support apparatus.
18. The person-support apparatus of claim 12 , wherein the input from the usercorresponds to at least one of a sound conditioning system mode and an audible sound adjustment, the sound conditioning mode including a sound masking function where an undesirable sound is masked by a masking sound, and an active sound controlling function where an undesirable sound is sensed, the phase of the sensed signal is inverted, and the inverted sensed signal is output by the sound generating device to interfere with the undesirable sound.
19. A person-support apparatus, comprising:
a frame;
a sound detecting sensor,
a sound generating device configured to generate an audible signal;
a graphical user interface configured to receive an input from a user, the input corresponding to at least one of a sound conditioning system mode and an audible signal adjustment; and
a controller electrically coupled to the sound detecting sensor, the sound generating device, and the user interface, wherein when the controller receives an input from the user interface activating the sound conditioning system mode, the controller controls the operation of the sound generating device in accordance with the input the sound detecting sensor to identify undesirable sound in the region of the person-support apparatus, generate a signal to cancel the undesirable sound, and simultaneously generate a separate masking sound.
20. The person-support apparatus of claim 19 , wherein the sound conditioning system mode includes a masking sound and an active sound formed when an undesirable sound signal is sensed, the phase of the sensed signal is inverted, and the inverted sensed signal is output by the sound generating device to interfere with the undesirable sound.
21. The person-support apparatus of claim 19 , wherein the controller is configured to control at least one other function of the person-support apparatus.
