A new technology has been developed that allows for personalized, location-specific audio delivery without requiring any special infrastructure or equipment beyond standard earphones. This system, known as UltrasonicSpheres, uses ultrasound to transmit audio signals to a user’s earphones, allowing them to receive targeted information and entertainment in public spaces.
The key innovation behind UltrasonicSpheres is its use of amplitude modulation (AM) to shift audio signals into the ultrasonic frequency range. This allows for the transmission of high-quality audio over long distances without interference or distortion. The system consists of a single speaker that emits an ultrasonic carrier signal, which is modulated with the desired audio content.
The receiver end of the system is made up of standard earphones that are equipped with a custom-designed digital signal processor (DSP). This DSP uses a combination of band-pass filtering and amplitude modulation to extract the original audio signal from the received ultrasonic signal. The result is a high-quality, location-specific audio experience that can be tailored to individual users.
One of the main advantages of UltrasonicSpheres is its ability to provide personalized content to multiple users in the same physical space. For example, in a museum setting, visitors could receive different audio descriptions or languages depending on their location and preferences. This would allow for a more immersive and engaging experience without disturbing other visitors.
The technology also has potential applications in areas such as education and entertainment. In an educational setting, students could receive targeted information and instructions based on their location and learning style. In the entertainment industry, UltrasonicSpheres could be used to create interactive and immersive experiences that engage audiences in new ways.
To demonstrate the capabilities of UltrasonicSpheres, researchers have set up a prototype system in a museum-like environment. Visitors can walk through different exhibits and receive audio content tailored to their location and preferences. The system has been shown to provide high-quality audio with minimal interference or distortion, making it suitable for use in a variety of public spaces.
Overall, UltrasonicSpheres represents an innovative approach to personalized audio delivery that has the potential to revolutionize the way we experience information and entertainment in public spaces. By using ultrasound to transmit targeted audio content, this technology offers a unique solution to the challenges of providing high-quality audio over long distances without disrupting others.
