Directivity Ratio

Directivity Ratio refers to how focused a source, like a speaker or antenna, is in directing energy, like sound or radio waves, in a particular direction compared to all other directions. Essentially, it measures how effectively the energy is concentrated in a specific area versus being spread out. A higher directivity ratio means the source is more directed, resulting in better performance in that direction, while a lower ratio indicates more general distribution. This concept is important in fields like acoustics, telecommunications, and broadcasting, where targeting a specific audience or area is crucial for effectiveness.
