The present invention relates to an ultrasonic transmission and reception device (1). Said device comprises a transmission circuit (20) for producing a transmission signal at its transmission outputs (21) and (21'), an ultrasonic transducer (40) that is suited to converting electrical signals into sound signals and sound signals into electrical signals, a transformer (10), the primary side (11) of which is connected to the transmission outputs (21) and (21') of the transmission circuit (20) and the secondary side (12) of which is connected to the ultrasonic transducer (40), and a reception circuit (30) for processing a received signal that is applied to its reception input (32). The ultrasonic transmission and reception device (1) is characterized in that the reception input (32) of the reception circuit (30) is connected to the transformer (10) via an additional winding tap (13) of the transformer (10), the additional winding tap (13) being incorporated into the transformer (10) such that the transformed transmission signal at the reception input (32) of the reception circuit (30) has its amplitude boosted with a lower gain factor than the transformed transmission signal that excites the ultrasonic transducer (40).
