how noise power affects the performnace of active noise cancellation ??
what would be response of active noise cancellation with increase and decrease of noise power ?
no..
i am using real electret microphones..which is not picking noise or any signal..
so what i do ?
at what voltage should i operate this micro phone?

why active noise cancellation is more effective at Lower Frequencies ??
and secondly how it fulfills the claim that it...
which type of microphone i should use to pick this ambient noise for my designed headset (ANC headset)??
i think it should be as sensitive as possible
what you will suggest??

hi !
how can i compare my designed headset with market available headphones quantitatively??
and able to say that how much much noise in attenuated in dBs with and with ANC circuit?
if my first diagram is correct, then it means i have to use 4 micro phones.. but in market available noise cancelling headphones, only 2 microphones are used.. then how first diagram could be correct..??
dear you still dont understand
actually its my project to design active noise cancellor headhones.. so i have implemented above mentioned circuit on breadboard.. but now i'have to connect this circuit with headphones.. and to take input signals(noise) i ll use micro phones.. so i am confused...
oh nope i am talking about its implementation in real life.. how i have to connect this ANC circuit with headphones..?? how i gave input.? how i take out put??
have a good day ahead !
how i have to connect this active noise cancellation circuit with headphones..??
i am bit confused about this..
so kindly guide me

its all fine.. :) but point is, either i must have to use a jack sort of thing to make connection with bread board..??? if so then which jack i have to use?? or i use audio line cable directly connected to breadboard.?
hello !
have a good day ahead :)
i have patched that circuit on bread board and getting expected and required results.. :)
for this circuit i have used Sinusoidal wave as a input from function generator..
but now i have to replace this input with an audio signal.. so i tried to give a tone...
i think its possible.. if i gave an audio siganl to ADC, the resulting output( digitized signal) is then to be inverted and this inverted signal then is to add with actual siganl, then their output (cancelled output) is to sent to DAC and then finally its output is to sent to headphones...
