[:es]Existen muchas soluciones basadas en el uso de arrays ac\u00fasticos, principalmente arrays de micr\u00f3fonos. Con la difusi\u00f3n de los arrays de sensores, se desarrollaron muchos estudios sobre t\u00e9cnicas de s\u00edntesis de patrones para mejorar su rendimiento. En primer lugar, estas t\u00e9cnicas se basaban en la variaci\u00f3n de las excitaciones de los sensores (amplitud y fase), manteniendo los sensores uniformemente distribuidos. A continuaci\u00f3n, se desarrollaron t\u00e9cnicas basadas en la variaci\u00f3n de las posiciones de los sensores, ya sea siguiendo ciertas reglas (arrays aperi\u00f3dicos) o de forma aleatoria, con excitaciones uniformes, y despu\u00e9s surgieron algoritmos que optimizan simult\u00e1neamente las excitaciones y las posiciones de los sensores.

Los micr\u00f3fonos digitales basados en tecnolog\u00eda MEMS (Micro Electro-Mechanical Systems<\/em>) incluyen un micr\u00f3fono, un acondicionador de se\u00f1al y un dispositivo de adquisici\u00f3n incorporado en el propio chip. Esta tecnolog\u00eda reduce considerablemente los costes del sistema, as\u00ed como el espacio ocupado por el mismo, lo que hace factible construir arrays con cientos o incluso miles de sensores.[:en]There are many solutions based on the use of acoustic arrays, mainly microphone arrays. With the spread of sensor arrays, many studies on pattern synthesis techniques were developed to improve their performance. First, these techniques were based on varying sensor excitations (amplitude and phase) while keeping the sensors uniformly distributed. Next, techniques based on varying sensor positions, either following certain rules (aperiodic arrays) or randomly, with uniform excitations, were developed, and then algorithms that simultaneously optimize excitations and sensor positions emerged.

Digital microphones based on MEMS (Micro Electro-Mechanical Systems) technology include a microphone, a signal conditioner and an acquisition device built into the chip itself. This technology considerably reduces system costs, as well as the space occupied by the system, making it feasible to build arrays with hundreds or even thousands of sensors.[:]<\/p>\n\n\n\n
