[data, FS] = wavread('YourWavFile.wav');
start_at_s = 5; %seconds
end_at_s = 7; %seconds
start_at_samp = max(ceil(start_at_s * FS), 1); %includes range check
end_at_samp = min( floor(end_at_s * FS), size(data,1)); %includes range check
sound_clip = data(start_at_samp:end_at_samp, :);

sir i have a wav file with a sound called "left". when i plot that, i will get some disturbance also. so i need to avoid that disturbance.

Where I wrote 'YourWaveFile.wav' you would use 'left.wav'
If you are asking to automatically detect and remove noise then that is a very different question than asking about clipping at specific times. You will need to tell us more about the kind of noise and how it differs from the sound you want.
