These devices are microphones sensitive to the ultrasound environment. To actually function, they require connection to a smartphone, tablet, or computer running compatible software. The advantage of these devices is that the software displays a live sonogram and makes high-end recordings which can be analyzed using sophisticated software later. The disadvantage is more complex connections, software, and expensive hardware necessary to function.
