Sažetak
One of the possible commercial applications of ultrasound is chasing the animals. To define the necessary ultrasound intensity and the frequency of the ultrasonic transducer, the ultrasound attenuation in the air has to be known. Because of the exponential increase of the attenuation with frequency, the lowest possible frequency of about 25 kHz, still inaudible by human ear, is chosen.
