hi friend's ,
Have you notice when you are talking in any busy street or crowdy place ,your caller often complain that he can't hear you , so is there any technology which can can provide any solution .
Answer is yes many of us must be aware of "active noise cancellation ".
let's try to understand how it's work .
Earlier old phone struggle due to single microphone .But now a flagship or mid range are coming with dual microphone , which actually creating wondered .
what both microphone do is they send signal to processor and it (processor) looks at the two soundwaves coming in. Working out which is your voice and which isn't is the dubious piece, it neutralizes whichever sound is undesirable and makes it quiet by turning around it.
A secondary microphone is help to reduce to remove unwanted voice & it's place somewhere in your phone, usually near the top and on the back of the handset.
guys I try to keep post short , easy to the word's only as briefing about technology is not an easy task ...how you like my efforts and will give full support so that in future I can bring more such post.
happy reading
