Abstract (en)

[origin: EP1655997A2] A method for amplification of an acoustic signal involves receiving a limiting amplification frequency curve (g) of the amplifying device which represents the limit for feedback whistling, and establishing a desirable amplification frequency characteristic (se) with several check-points, in which each check-point has a specified minimum spacing to the limiting amplification curve in at least two different directions in the amplification-frequency diagram. An independent claim is included for an acoustic system with amplification device.
