CameronJ Posted February 1, 2019 Posted February 1, 2019 Very cool! I wonder what the fidelity of the audio is like? Quote
Maude Posted February 2, 2019 Posted February 2, 2019 Even better if it was the future for PAs.Ā It would be like a silent disco except you wouldn't need the headphones. Everyone within range (ie in front of the stage area) would hear the band but zero noise pollution in the rest of, or outside of the venue. People could chat at the bar easily and those complaining dĀ”cks who bought the house next door could go f themselves.Ā 1 Quote
chris_b Posted February 2, 2019 Posted February 2, 2019 I invigilate for exams and we are already having trouble with cheating using all levels of technology, from paper to digital. If some of these people spent half the effort on learning as they do on cheating they'd all have firsts! If this technology comes of age the results of tests and exams will be questionable and that'll be the end of reliable academic qualifications. Quote
