This paper describes the method of adaptive LMS algorithm for noise cancellation. In MRI method acousticnoise is produce due to the communication between medical staff and patient also produces due to high magnetic (3 -T)field and higher power. This acoustic noise interferes with diagnosis and imaging process. In MRI system level of strongacoustic noise is greater than 120dB SPL (Sound pressure level). In MRI system signal to noise ratio is very low due toavailable of strong acoustic noise. For removing the noise and recovering the original speech signal in MRI we employ atwo channel adaptive least mean square algorithm. In this paper, the main aim is remove the noise in speech signal andimprove the quality of speech signal especially for noisy magnetic resonance imaging environment.
