Loudspeakers Array

A loudspeaker line array is a sound system constituted by a linear group of loudspeakers. The linear setup gives particular characteristics to the sound field, so that a line array is considered a very useful sound system in the sound reinforcement area. Many studies have been carried out on the design and use of vertical line array in theatres, concerts, cinemas, conference halls, etc. A very important aspect of the sound field emitted by a vertical line array is referred to the possibility of pointing in a particular direction the main lobe of the sound beam by using digital signal processing techniques.

The main topics are:

• Digital Directivity Control: frequency independent main lobe amplitude
• Linear and Curve arrays: electronic and mechanical combination
• Secondary lobes control and attenuation
