Patent Issued for Audio Direction-Distance Detection

July 2, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Ross, Marcus E. (North Las Vegas, NV); Sugden, Scott A. (NewburyPark, CA), filed on December 12, 2011, was published online on June 17, 2014.

The assignee for this patent, patent number 8755534, is Sound Services, LLC (St. Francis, WI).

Reporters obtained the following quote from the background information supplied by the inventors: "A speaker in an audio system is generally non-directional in the projection of sound produced by the speaker. To direct the sound towards an area, a housing for the speaker is pointed in a direction of the area to which the sound is to be directed.

"Tolerance for poor acoustics for an event in a performing arts venue is particular low. As such, an audio engineer has a keen appreciation that in a theatre, stadium, or auditorium (e.g.; a 'concert venue'), there are many areas to which sound is to be uniformly directed so as to achieve for each audience member an acoustically esthetic listening experience.

"A particular problem for the audio engineer responsible for overall acoustics in a concert venue is whether sound is being directed to the proper audience locations, given the many speakers in the concert venue. It would be an advance in the art to concert venue with a capability to direct, at a numerically verifiable angle, the output of sound from each speaker within the concert venue towards a precise location therein."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "A laser is used with an inclinometer to make one or more adjustments to a position of a sound producing device. Both the laser beam of the laser and an output from the inclinometer characterize a general direction of sound produced by the sound producing device. The inclinometer will preferably be mounted and calibrated to ensure that its output characterizes the general direction of sound produced by the sound producing device--either by an interpretive output and/or by deduction from its output. The laser will be similarly mounted such that the direction of its laser beam will characterize the general direction of sound produced by the sound producing device."
