No, in simple interference the frequency is constant.It would take something nonlinear in the system to produce changes in frequency.
Is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Ultrasound imaging is a common diagnostic medical procedure that uses high-frequency sound waves to produce dynamic images (sonograms) of organs, tissues, or blood flow inside the body.
