The invention relates to a sensor for measuring the amplitude difference and/or the intensity value of sound, said sensor being provided with a piezo-sensor (4), such as a piezoelectric transducer (12), characterized in that the sensor (4) comprises a housing (5) which is made of a material having a strongly absorbing capacity for sound and/or vibrations, such as silicones, for example, while at least one piezoelectric sensor (12) is embedded in said housing (5).
