In an ultrasonic frequency we can’t hear. But your pets and any nearby bats or rodents etc may be upset by it..

Can't hear but still cause damage?

Yes. Industrial grade ultrasonic sensors are harmful to your health. They can be used, for example, to measure the water level in a tank. If you need to enter a place like that, you should physically disconnect the sensor first. You might not hear much of the noise, but you may feel it in your teeth or some other places.
