DIRECTIVITY Meaning and
Definition
-
Directivity is a term used to describe the characteristic of a device or system, particularly in the field of audio technology and antenna design, to emit or receive sound or signals more effectively in certain directions. It refers to the ability of a device to focus its output or reception in a specific direction, resulting in enhanced performance and targeted transmission or reception.
In audio technology, directivity is a crucial aspect for speakers and microphones. Speakers with a high directivity are designed to project sound accurately and efficiently toward a specific direction, minimizing dispersal of sound energy to unwanted areas. This is particularly useful in situations where sound needs to be concentrated in a specific direction such as public address systems, stadiums, or concert halls. On the other hand, microphones with high directivity are engineered to pick up sound predominantly from a specific direction, reducing interference from background noise and providing clear and focused sound capture.
In antenna design, directivity refers to the ability of an antenna to focus its radio frequency signals or receive them effectively from a specific direction. This is crucial in applications such as wireless communication systems, where directional antennas can increase the signal strength, improve reception quality, and minimize interference from unwanted sources.
Directivity is often quantified using terms like omnidirectional (equal sensitivity in all directions), unidirectional (preferential sensitivity in one direction), bidirectional (preferential sensitivity in two opposite directions), or multi-directional (preferential sensitivity in multiple directions). Additionally, directivity is measured in decibels (dB) to provide a quantitative assessment of its effectiveness in targeting or focusing sound or signals.

Etymology of DIRECTIVITY
The word "directivity" is derived from the adjective "directive", which is formed from the noun "direction".
