The way which we listen to music and hear sounds has changed the centuries. Today, we have state--the-art, noise-cancelling ear buds that provide the highest quality aural experience. In the near future, we will be able to listen to music public headphones. New technology is being tested that can aim beams sound at individuals, without people next to them hearing. This means we could be having private conversations in public others listening in. A team of researchers at Penn State University the USA developed an innovation called "audio enclaves". The ultrasound waves used for these enclaves cannot be heard en route to the recipient. addition, the waves can be bent to get obstacles.
The researchers spoke to the website "The Conversation" their work. Lead researcher Jiaxin Zhong said: "We essentially created a virtual headset. Someone an audible enclave can hear something meant only them, enabling sound and quiet zones." He elaborated the potential uses of the technology. Museums could provide headphone-free audio guides to visitors. Passengers a car could listen to music distracting the driver. Those requiring confidentiality could set enclaves to ensure their conversations are not overheard. Individuals could also receive personalized ads as they walk a shopping mall. In addition, audio enclaves could be set to eliminate noise pollution busy workplaces.
