One of the most exciting innovations in sound technology is ultrasound directional speakers. They control how sound waves move through the spaces that people visit. They not only grab attention and improve the way art is consumed. They also open up new marketing opportunities. In short, directional speakers available from Focusonics website have many use cases in different industries.
But how do ultrasonic directional speakers work? How do you use them effectively? This detailed guide dives deeper into the world of ultrasonic directional speakers to provide answers to these questions and more. Read on for more details.
How do Ultrasonic Directional Speakers Work?
The use of directional audio tools has entered almost every aspect of life. This innovation uses ultrasonic directional speaker technology. For instance, there are directional audio safety prompts at intersections waiting for traffic lights.
These audio safety prompts can be directed to pedestrians who are waiting for traffic lights. These prompts do not produce noise effects. As a result, they create a comfortable environment for citizens.
Directional Audio Technology: Special Features
The audible audio that the common speakers emit is a mechanical wave. Its circulation is divergent, spherical and easy to attenuate. The audible sound wave is usually radiated 360o. At different angles and frequencies, the sound wave energy will be unique. That means it’s easy to attenuate when propagating in the air.
The 360-degree radiation feature means that the audible sound wave will propagate in all directions. And that means disturbing others who aren’t interested. The highly super-directional sound tool uses ultrasonic directional speaker technology as a carrier signal.
It modifies the audio into a high-frequency signal in order to achieve directional transmission in the air. Self-demodulation allows the human ear to capture the restored audio signal.
Where and How to Use Ultrasonic Directional Speakers Effectively
The use cases of directional speakers are limitless. They are suitable for:
- In-store displays
- Hospital televisions
- Digital signage
- Museums and galleries
- Virtual source effects
- Offices and more
How to Use Directional Speakers Effectively
Due to the numerous ways that directional speakers work, they are ideal for high-range and mid-range sounds. That includes radio-friendly music such as classical, jazz, or pop, natural sound effects or soundscapes, and the spoken word.
Directional sound is perfect for keeping a higher rate of recurrence sounds within a narrower beam. On the other hand, low-frequency bass sounds tend to spread out in dissimilar directions. You need to be creative and predict correctly how sound users will end up accessing it.
Thoughtfully pick the sound field where your visitors or target audience will hear the sound beam excellently. Will they require visual encouragement, such as floor stickers or signs? Or will they stand in the best listening position naturally?
Also, will your audio clash with nearby sounds? Directional speakers are great for enhancing the senses and concentrating attention. So, thoughtfully consider the part of your space to highlight and boost the sound experience. You don’t have to find solutions to these questions or make decisions straight away. It’s advisable to experiment and see what the users respond to best.
