A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded ...
A disadvantage of the systems described above is a relatively slow rate of survey. One solution to this has been wheeled arrays. These use spiked wheels or metal disks as electrodes, and may use a square array (a variation of the Wenner array) to avoid the encumbrance of a trailing cable. Wheeled arrays may be towed by vehicles or by human ...

A large line array with separate subs and a smaller side fill line array. A simple and inexpensive PA loudspeaker may have a single full-range loudspeaker driver, housed in a suitable enclosure. More elaborate, professional-caliber sound reinforcement loudspeakers may incorporate separate drivers to produce low, middle, and high frequency sounds.
A sensor array is a group of sensors, usually deployed in a certain geometry pattern, used for collecting and processing electromagnetic or acoustic signals. The advantage of using a sensor array over using a single sensor lies in the fact that an array adds new dimensions to the observation, helping to estimate more parameters and improve the estimation performance.
Hackaday was founded in 2004 by Phillip Torrone as a web magazine for Engadget, devoted to publishing and archiving "the best hacks, mods and DIY projects from around web". [2] Hackaday was since split from Engadget and its former parent company Weblogs, Inc. by its at the time owner Jason Calacanis .
The first module, a linear array, was completed in 1960. It formed the basis of the AN/FPS-85. [1] Starting in the 1960s, new solid-state devices capable of delaying the transmitter signal in a controlled way were introduced. That led to the first practical large-scale passive electronically scanned array, or simply phased array radar.
