An ultrasonic transducer includes an arrangement of ultrasonic transducer elements, wherein the ultrasonic transducer elements include a first ultrasonic transducer element and a second ultrasonic transducer element. The first ultrasonic transducer element has a first membrane having a first membrane reinforcement and a first membrane electrode, and a first counter-electrode. The second ultrasonic transducer element has a second membrane having a second membrane reinforcement and a second membrane electrode, and a second counter-electrode. Additionally, a resonant frequency of the first membrane differs from a resonant frequency of the second membrane.
