Unlike normal sound, directional audio is able to project sound beams on a specific area. It can also be used to locate hazards nearby. This is useful for safety applications in museums and exhibitions. Visit Focusonics website for information about the Focusonics directional speaker.
Creating a sound beam
Using the power of directional audio, you can create a focused beam of sound that can have a powerful effect on your body. Sound beam technology has shown significant promise for many applications and will likely see widespread adoption in the near future.
The most important part of this technology is the ability to control the beam. By using a variety of audio technologies, you can create thin directional sound beams.
The acoustic signal produced by the waves in air is known as intermodulation. This is one of the most interesting things about directional audio.
A small speaker placed half a meter away from a wall can provide some directionality. For a more substantial effect, you could use a speaker the size of a small building.
The ability to create a narrow beam of audible sound is achieved using parametric arrays. These arrays can cover a localized feeding area or the entire room.
It is also possible to use a combination of electronic and mechanical phased array technologies. These systems can achieve sufficient beam steering performance.
One of the more exciting new applications is in the entertainment industry. Sound beam technology could improve movie theater sound effects. It also could serve as an effective non-lethal acoustic weapon.
Several companies have started purchasing this technology. One of them, Holosonic Research Lab, claims that it is the only directional sound system on the market. You can read more about the applications here on the website of fucosonics.
Detecting nearby hazards
Touted as the real deal, Ford’s upcoming flagship sedan will be more of a handful than a pack of eels. Having said that, the company has a litany of wacky ideas that will no doubt earn the company a spot in the top ten of carmakers for the rest of your life. Fortunately, the good people at Ford have a penchant for letting their research and development departments run wild and free. After all, they’re the ones that came up with the idea in the first place. They’re also a nifty noun and an affliction to boot. Having said that, it’s no small feat balancing the yippiest in the country with a hefty ad budget. And, the aforementioned ad budget means that they have the green light to innovate. It’s also a given that the company is in the midst of a major redesign. So, the company has a chance to test out a plethora of cutting edges technologies.
Applications in museums and exhibitions
Using directional audio in museums and exhibitions can enhance the experience for visitors. Museums and exhibitions are often full of ambient noise. This can distract visitors and weaken the overall experience. To improve the visitor experience, directional speakers can be used to announce areas of the museum and to provide information.
Museums can benefit from directional audio systems because they reduce noise and create a tranquil environment. A directional speaker broadcasts a high-quality audio guide in a narrow beam, which eliminates sound spill and provides a clean and quiet experience.
Directional speakers also provide the flexibility of adjusting the sound levels to match the visitor’s level of understanding. They can also be used to help manage dwell time.
Museums and exhibitions need to provide a soothing and comfortable environment to visitors. They can also enhance the sensory dimension of the display. In addition, directional speakers are a great way to announce areas of the museum, hold a conversation, and reduce touch in public spaces.
One innovative use of directional audio is to enhance an interactive light display. A speaker system is integrated into each display area, which produces directional sound. These audio beams are then integrated with infrared sensing devices, which create an intelligent stop and go effect. The speakers can also be used to broadcast descriptions of images.
