The Application Principle of Directional Loudspeakers

For many, the concept of pollution is limited to nature and the environment. But noise has a tendency to disrupt the natural rhythm of life and is therefore also a form of pollution. Studies have found that noise above 85 decibels can make people feel noisy, upset, insomnia, irritable, and irritable. Noise pollution can have a great impact on people's physical and mental health. So to solve noise pollution, we must rely on the power of science and technology. That's it for directional speakers!

1. What is a directional speaker?

We all know that most of the sound waves emitted by traditional speakers radiate 360 degrees, and these sound waves are spherical waves. The sound emitted by directional speakers is more like a spotlight composed of sound waves, focusing like a flashlight, allowing the sound to spread to the desired area, with strong directivity. Directional speakers can control sound waves in a specific area, where the sound waves are strong, and outside this area, the sound waves are weak or even non-existent.

2. Understand the use of directional speakers

Directional speakers can control sound waves in a specific area, where the sound waves are strong, and outside this area, the sound waves are weak.

When children need online classes, parents need video conferencing, and the elderly want to watch TV, multiple devices output audio at the same time. Based on the propagation characteristics of sound in the air, it is easy to form a mixed sound scene. The directional speakers have super directivity to ensure the audience can clearly obtain the voice information in the front position, avoid the sound mixing together and form interference, thereby reducing the impact of noise.

Directional speakers can be used in advertisements, exhibitions, digital signage, airport halls, museums, etc., to achieve directional broadcast of sound for the desired population. High-power active directional loudspeakers can be used in areas such as fog channel command, air traffic security command, and anti-terrorism. In the future, the use of directional speakers is bound to be more extensive.
