Abstract
So as to shape the spatial amplification characteristic of an acoustical to electrical converter arrangement at least two sub-arrangements (I, II) of converters are provided, generating different spatial amplification characteristics. Frequency domain converted signals ({tilde over (S)} ) which are proportional to the output signals of the sub-arrangement are compared in a unit ( ) on respective spectral frequencies (f ) and there is generated at the output of the comparing unit ( ) a binary spectral comparison result signal (A ). Signals ({tilde over (S)} ) which are as well proportional to the output signals of the sub-arrangements (I, II) are fed to a switching unit ( ). For each spectral frequency (f ) the control signal from unit , as a binary spectral signal, controls the spectral amplitude of which of the two input signals ({tilde over (S)} ) is passed to the output (A ) of the switching unit and of the arrangement.
