Sony drone patent application for noise cancellation – suas news

A really large thanks to Lauren Hawksworth from Founders Authorized for emailing and telling me about this! There may be little doubt that Sony is shifting!

A brand new USPTO patent utility from Sony was revealed relating to a method of working a fleet of drones to supply noise cancellation in a particular space. 

In accordance with the patent’s background data:

“In sure conditions of open areas (for instance, eating places, celebration locations, parks, and so forth), it might be tough to get the soundproof mounted infrastructure immediately to provoke a verbal communication (similar to telephonic name, a dialog with close by individual). Additional, the verbal communication or sound replica carried out within the open areas could create a disturbance or nuisance for neighboring individuals. Thus, a complicated and clever system could also be required which can present a soundproofing answer on a real-time foundation.”


This invention seeks to allow a method of getting a digital noise cancellation barrier by a networked system of drones. The drones are geared up with the required audio gear wanted to cancel out the ambient noise of the setting and supply the customers throughout the digital barrier a noise-free zone. Such a system may very well be used to supply privateness in a beforehand public space, or assist cut back noise in a loud space whereas making an attempt to speak with others. The true implementation of this know-how may take many types, from industrial purposes in mines and factories to shopper purposes in large cities. The flexibility to create a digital noise barrier may be leveraged in many alternative methods and is certain to be broadly carried out as soon as the know-how has matured sufficient.


It is a very advanced invention, however when damaged down into two elements it’s simpler to know how the general system works. Earlier than we analyze particular person aspects of the invention let’s set up some fundamentals of the system. This technique is executed by a fleet of interconnected unmanned drones outfitted with audio system with the objective of surrounding and offering noise cancellation to a predetermined 3D space.

The primary facet of this invention is controlling the drones. These interconnected drones know the place to go primarily based on a picture processing algorithm. The algorithm identifies the predefined 3D space from a real-time picture information feed and sends corresponding instructions to the linked drones to place them accurately. By way of the usage of the real-time feed, the fleet of drones is able to following particular targets to supply a continuous zone of noise cancellation.

The second facet of this invention is noise cancellation. As beforehand talked about, the drones are outfitted with audio system. As soon as the drones have been correctly positioned, they use their audio seize skills to course of the ambient sound in a given space. The audio system geared up with the drones are then able to creating audio indicators that cancel the processed ambient noise leading to digital noise cancellation boundary.

One key ingredient of this invention is how a lot information processing is really required to perform each elements of this method, even earlier than making an attempt to combine them. Processing picture information to manage drones in addition to the processing and canceling ambient noise is a computationally-intensive course of. Combining these two extremely advanced techniques to work in tandem is not any small feat.
