Ultrasonic devices are industrial control devices that emit a sound beyond the reach of the human ear.
Although these devices are very important in the industrial sector, it is not correct to allow them to be used normally in people's daily lives. That is why, this type of device, although not detected by the human ear, can be detected by devices. This could encourage the passing on of valuable information that would harm some individuals, in addition to being able to be used for various criminal and dishonest activities.
In this case, it is important that laws and guidelines that limit the use of these devices outside the industrial sector are encouraged, promoting a more honest society and preventing criminal activities from being carried out.
