Thanks to this, the user will better hear the interlocutor during a conversation in a crowded place where there is a large amount of extraneous noise. To implement the technology, several microphones were placed on the device, which is used to capture the sounds surrounding the user. The headset monitors the user’s head and eye movements and based on the collected data, it determines which sounds they want to hear and which ones should be filtered. Although the development of an AR headset is not focused on creating a device for the hearing impaired, the device may prove useful for people who do not want to use a hearing aid in their daily life.

“ By putting people with hearing impairments on a par with people with normal hearing, we could help them become more socially involved. This echoes Facebook’s mission in that hearing loss often keeps people away from social situations, ”said Thomas Lunner, one of Facebook’s AR headset designers, who also helped create the world’s first digital hearing aid.

The developers also talked about the “Audio Presence” technology, with the help of which the headset is able to recreate virtual sounds that do not differ from real ones in terms of perception. This makes the sounds emitted by the headset realistic, and the user feels that he actually hears what is happening around, and not what the device gives out.
