| 1. A method for amplifying electric signals comprising the steps of:
providing an acoustical to electrical converter arrangement for generating an electrical output from acoustical signals of
one or more acoustical sources impinging upon said converter arrangement; and
generating said output by selecting a particular distance out of a plurality of selectable distances and automatically amplifying
said acoustical signals, such that if the acoustical sources are located in said selected distance said acoustical signals
are amplified differently than if the acoustical sources are located in a different one of said distances.
