How to use a Directional Loudspeaker

Each sound does not interfere with each other, and only the sound of the ad you are looking at is heard.

Sound can be transmitted only to the desired area, so effective information can be provided.

The announcement can be delivered to those who need attention without being assimilated to ambient noise.

Sound can be delivered only to where you want without noise damage to the surrounding areas.
