Abstract:
1. A bed equipped with a plurality of noise detection devices capable of detecting direction and magnitude of noise to control angles of inclination of panels attached to the bed, the bed comprising: a bed frame with a first bedside, second bedside, third bedside, and a fourth bedside; a first sound detector attached to the first bedside facing a first direction configured to detect magnitude and direction of noise coming from the first direction; a second sound detector attached to the second bedside facing a second direction configured to detect magnitude and direction of noise from the second direction; a third sound detector attached to the third bedside facing a third direction configured to detect magnitude and direction of noise from the third direction; a fourth sound detector attached to the fourth bedside facing a fourth direction configured to detect magnitude and direction of noise from the fourth direction; a first rotatable panel hinged on the first bedside, wherein the first rotatable panel is rotatable along the first bedside and is fixable in an inclined position having a particular angle of inclination; a second rotatable panel hinged on the second bedside, wherein the second rotatable panel is rotatable along the second bedside and is fixable in an inclined position having a particular angle of inclination; a third rotatable panel hinged on the third bedside, wherein the third rotatable panel is rotatable along the third bedside and is fixable in an inclined position having a particular angle of inclination; a fourth rotatable panel hinged on the fourth bedside, wherein the fourth rotatable panel is rotatable along the fourth bedside and is fixable in an inclined position having a particular angle of inclination; an air-conditioned vent attached to each of the first, second, third, and fourth rotatable panels, wherein the air-conditioned vent increases airflow from an air conditioner when one of the rotatable panels is rotated to a position covering a portion of a top part of the bed, and ventilates the bed when one of the rotatable panels is rotated to a position covering the top part of the bed; a sound generator associated with the air-conditioned vent, wherein the sound generator produces destructive interference sound waves to offset incoming noise; a processor attached to the frame, where the processor executes instructions stored in memory, the instructions comprising:
