Devices and methods for audible indicators emanating from selected locations

摘要

Methods, systems, and devices are described for providing audio to one or more individuals in an operating room. An ultrasonic signal generator may be provided that generates two or more ultrasonic signals that combine to produce an audible signal at a desired location. The audio signal may be perceived by individuals in the operating room to emanate from a surface or location within the operating room, or the audio signal may be generated to provide an audible signal to one or more persons within a particular location within the operating room. Multiple audio signals may be generated to emanate from multiple different locations. Likewise, multiple audio signals may be generated to provide different audible signals in different locations in the operating room.

主权项

1. A method for providing audio to one or more individuals in an operating room, comprising:
identifying a first location within an operating room from which it is desired to have sound emanate; and configuring first and second ultrasonic sound transducers at one or more locations in the operating room different than the first location to focus first and second ultrasonic sounds to the first location, wherein the first and second ultrasonic sounds generate an audible sound substantially at the first location of the operating room, and wherein the first and second ultrasonic sound transducers are configured so that the audible sound is synchronized with at least one information source located in the operation room.
