Steady-state characterization of acoustic environment is not enough for an efficient compensation. Therefore a new concept of equalization can be defined. It relies on dynamic frequency response and on articulation to design the equalizer shape. Specifically the inverse filter shape will be based on the dynamic frequency response instead of on the steady-state frequency response. This is obtained relying on AQT methods, which use a variable frequency burst as a stimuli. Moreover the inversion will be based on a target frequency response shape, which corresponds to a maximum pleasantness.
