The magnetic Barkhausen noise (BN) is measured at controllable magnetization conditions: the triangular field and induction waveforms. A special attention is paid to an unexplored topic of the subsurface BN measurement with the controlled surface field waveform. It is demonstrated that the shape of the BN rms profile (envelope) can be noticeably changed at different magnetization conditions and that the primary reason of these changes is a variation of the field rate dH/dt.
