Speech enhancement technology is suitable for large rooms where participants at both ends of the room find it difficult to hear each other's voices.

The minimum size of a room is usually about 12 meters x 12 meters, and the distance between the speaker and the audience is at least about 7.6 meters. The above data can be used as a suitable reference.

Because if it is still difficult to hear the other person's voice in a smaller room, it may be necessary to use acoustic methods to solve problems such as excessive noise generated by air handling, corridor pedestrian flow, electronic equipment, etc.

In theory, there is no limit to the size of the room where the voice enhancement system is installed, and instead, the requirement for ceiling height has a greater impact on the success of the system than the size of the room.

In most cases, ceiling microphones are installed between approximately 2.4 to 3.6 meters above the floor, depending on the indoor sound field, and may also be installed at a higher position.

Speech enhancement is very effective in many applications and environments, especially in interactive and multi-directional conversations, such as situations where there are many students or attendees as listeners, and a main lecturer or spokesperson on the podium.

In training rooms, report halls, and even large conference rooms, voice enhancement makes it easier for attendees from any position inside to hear the entire room.
