In order to hear ultrasound waves, traditional speakers will not suffice. A different type, known as a parametric or ultrasound speaker, is required. These specialized speakers are designed to target specific locations instead of projecting sound throughout an entire room or space. Here is some information about the technology behind this type of speakers and its various uses.
How do Ultrasound and Parametric Speakers work?
Contrary to loudspeakers that we find in our homes or in public spaces, an ultrasound or parametric speaker uses ultrasonic directional speaker technology to emit sound. Instead of using traditional audio frequencies, they use shorter wavelength ultrasounds. This allows the sound to travel in a narrow beam and reach a specific location within a given space. As a result, these speakers are able to create almost complete silence, except to the ears of those positioned in the designated spot that will get to hear the directed sound.
Despite their differing operational principles, both types of speakers achieve the same effect by precisely directing the sound and preventing it from propagating throughout the space. In parametric speakers, the sound demodulates upon reaching an individual or object, while ultrasound speakers use narrow tunnels to reach their intended target.

What is the use of Ultrasound Waves Technology?
You might be curious about the purpose of ultrasound wave technology, as it does not broadcast sound for everyone in a room to hear. However, there are numerous practical applications for this type of speaker, both in commercial and non-commercial settings.
From a commercial standpoint, ultrasound speakers allow businesses to target specific customers individually inside their stores. As shoppers walk through the aisles, they may encounter a message played by one of these speakers, which will only reach them when they pass a certain product.
In the workplace, employees can receive specific instructions through directional speakers from their supervisor or colleagues without disturbing others who are busy working. And in museums and galleries, such speakers can provide valuable information to individuals observing works of art, enhancing their experience and understanding of the piece in front of them.
Conclusion
As you can tell, the use of ultrasound waves has expanded to encompass numerous functions in modern society. It is easy to envision that as further technologies advance, so too will the potential for even more applications.
