How Can Directional Sound Impact Industries?


Directional sound is one of the latest innovations in the audio-visual media world. This innovation is unique when it comes to applications in different industries. As a result of its popularity, numerous brands are offering directional sound speakers and systems, each with its unique formula.

Focusonics directional speakers are just one example manufacturer, with its wide range of systems designed for different use cases, from retail digital signage to announcement systems. In this article, you’ll learn more about directional sound speakers, including what they are, how they work, their various applications, and how they differ from conventional speakers. Read on to discover more.

What is Directional Sound?

Directional speakers are designed to produce directional sound – a relatively new concept. This concept mainly utilizes the ultrasonic signals’ nonlinear effect in the surrounding air to create unique signals known as audible sound differences. The audible sound difference frequency signals have excellent directivity and isolation.

Directional sound is similar to a spotlight of sound waves concentrated like a flashlight. These sound waves spread out in a fan shape covering the area in front of the source system, enabling the sound to spread to the preferred area effectively.

It’s angular and directional – the long-distance volume transmission is almost not diminished. The specific sound transmission distance can be tuned based on different application needs and requirements.

How Are Directional Speakers Different from Conventional Speakers?

Directional speakers function in an entirely unique way from their conventional counterparts. The main difference is that directional speakers do not generate ordinary, audible waves of sound with one moving electromagnetic cone or coil.

Instead, these speakers create high-frequency sound (ultrasound) waves that are high-pitched for human ears to hear using different electrical devices known as piezoelectric transducers. Ultrasound is used since it has higher-frequency waves that have shorter wavelengths.

These higher-frequency waves also spread out less as they transmit, meaning they stay together in a beam longer than ordinary sound. Also, having many tiny transducers makes the sound spread less than it would from a large transducer.

What Are the Various Applications of Directional Sound Speakers?

Directional sound is used in exhibitions and museums. Besides art venues which other fields utilize directional sound technology?

Other fields that utilize directional sound technology include interactive art displays, retail, digital media billboards, hospitals, and banks. Cars, libraries, homes, and bus stop signs are additional use cases.
