The video could discuss the purpose behind the unique two-prong plug found on headphones provided on a flight. You could have discovered these headphones during a trip and wondered why they had a different plug compared to standard headphones. The two-prong plug was designed to prevent people from walking off with them, as they would not be compatible with regular devices. The video could explain that the two-prong plug is not for redundancy but for the active noise cancellation functionality. There are two microphones in the headphones that pick up the external noise, and the canceling waveform is generated and mixed into the audio to cancel out the noise. The active noise cancellation processing does not occur on the headphones themselves, but on an external computer on the plane. This makes the headphones cheaper to produce and replace, as the computing power is located elsewhere. The audio quality of these headphones is not particularly special and that the noise cancellation feature is not very effective. Overall, the purpose of the two-prong plug is to discourage theft and reduce costs for the airline. Credits#brightside Animation is created by Bright Side. ---------------------------------------------------------------------------------------- Music from TheSoul Sound: https://thesoul-sound.com/ Listen to Bright Side on: Spotify - https://open.spotify.com/show/0hUkPxD34jRLrMrJux4VxV Apple Podcast - https://podcasts.apple.com/podcast/idhttps-podcasts-apple-com-podcast-bright-side/id1554898078 ---------------------------------------------------------------------------------------- Our Social Media: Facebook - https://www.facebook.com/brightside/ Instagram - https://www.instagram.com/brightside.official/ Tik Tok - https://www.tiktok.com/@brightside.official?lang=en Snapchat - https://www.snapchat.com/p/c6a1e38a-bff1-4a40-9731-2c8234ccb19f/1866144599336960 Stock materials (photos, footages and other): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru ---------------------------------------------------------------------------------------- For more videos and articles visit: http://www.brightside.me
