Hi everyone...I am getting transient peak in the signal from 0 to 6000 hz in the sound pressure level plot. Can anyone suggest me how to remove it?

If you are referring to the series of ‘spikes’, the easiest way would be to use findpeaks to define the spikes and the frequencies at the spike centres, and then use a FIR filter to remove them. This first requires that you share the data (if you want help to design the filter), and second that the signal is long enough to work with a FIR filter, since FIR filters are themselves usually long.
Use filtfilt to do the actual filtering.
