In this paper, system on a , analyzing of echo cancellation in audio signal when reverberated in real environment , this type of filter is mainly used to control the echo noise in the sound like orchestra etc. In general, the echo noise reverberated in the real environment is filtered by kalmans algorithm. This kalmans algorithm is mainly to reduce the eror noise in the audio signal. This effect will avoid disturbance to the patients without any physical discomfort. We implement this phenomenon by using sound detection and finding the propagation path and the impulse response of the audio signal by kalmans filtering to reduce the echo noise reverberated in the real environment. We discuss performance analysis scenarios of the system, such as facilitating and reducing echo noise. Finally, the system parameters are analyzed and the gain of the signal is calculated and the error performance is calculated.
