The process is , and comprises adjusted periods with alternating high and low sound strength through signal damping or signal amplification. An electrical signal is emitted from a signal emitter (11) such as a tape recorder and is received-processed by one or more sound reproduction units (13,14). The electrical signal is damped or amplified periodically (cyclically). Each period is adjusted with a section where the sound reproduction unit (14) emits sound at low strength and a section where sound is emitted at high strength. This is achieved using at least one signal damping-amplifying unit (12) connected between the signal emitter (11) and the sound reproduction unit (14) and having a clock circuit, time adjustment unit, an activating memory circuit, a deactivating memory circuit and a damping-amplification circuit. |
