Abstract

An apparatus for producing sounds corresponding to the operation of an internal combustion engine in the interior space of a motor vehicle is characterized by a pressure sensor (20) that detects fluctuations in pressure in a fresh air stream into the engine, an amplification device (32, 33) for amplifying output signals of the pressure sensor, and at least one speaker (34) attached to the amplifier and arranged in the interior space of the vehicle for reproducing the amplified signals.
