\n

El sonido se refiere a ondas de presi\u00f3n que pueden propagarse en gases, l\u00edquidos y s\u00f3lidos, pero no en el vac\u00edo. La causa es siempre una fuente sonora que provoca una deformaci\u00f3n mec\u00e1nica propagadora del medio de transmisi\u00f3n.<\/p>\n\n\n\n

Los efectos del sonido en el medio de propagaci\u00f3n dependen esencialmente de la forma de la onda, de la intensidad de la fuente y del tipo de medio. Por ejemplo, en los l\u00edquidos y los gases s\u00f3lo se propagan las ondas longitudinales; esto significa que las ondas sonoras provocan una fase peri\u00f3dica de empuje y tracci\u00f3n en la direcci\u00f3n de oscilaci\u00f3n.<\/p>\n\n\n\n

En ac\u00fastica, se distinguen las siguientes gamas de frecuencias.<\/p>\n\n\n\n

Infrasonidos<\/p>\n\n\n\n

0 Hz < f < 20 Hz
Ruido ac\u00fastico<\/p>\n\n\n\n

16 Hz < f < 20 kHz
Ultrasonidos<\/p>\n\n\n\n

16 kHz < f < 1 GHz
Hipers\u00f3nico<\/p>\n\n\n\n

f > 500 MHz
1 Hz = 1 oscilaci\u00f3n por segundo = 1 hercio<\/p>\n\n\n\n

Ultrasonido es el t\u00e9rmino utilizado para describir ondas sonoras por encima del umbral de audici\u00f3n humano en una gama que va de unos 16 kHz a 1 GHz. Los ultrasonidos tambi\u00e9n pueden generarse con bastante m\u00e1s energ\u00eda, es decir, \"m\u00e1s fuerte\" que el sonido audible.<\/p>\n\n\n\n

Las aplicaciones de los ultrasonidos se dividen a grandes rasgos en aplicaciones de peque\u00f1a se\u00f1al y de sonido potente<\/p>\n\n\n\n

Aplicaciones de peque\u00f1a se\u00f1al: Intensidad 100 kHz<\/p>\n\n\n\n

Aplicaciones de sonido de potencia: Intensidad > 1 W\/cm\u00b2 y frecuencia < 100 kHz<\/p>\n\n\n\n

Tambi\u00e9n hay aplicaciones que no encajan en este esquema:
La terapia m\u00e9dica requiere bajas frecuencias a bajos niveles de potencia, mientras que la industria de las obleas requiere altos niveles de potencia a altas frecuencias.<\/p>\n\n\n\n

De las \u00e1reas de aplicaci\u00f3n mencionadas, BANDELIN electronic est\u00e1 especializada en<\/p>\n\n\n\n

Limpieza - Homogeneizaci\u00f3n - Terapia m\u00e9dica<\/p>\n\n\n\n

Mit Schall bezeichnet man Druckwellen, die sich in Gasen, Fl\u00fcssigkeiten und Festk\u00f6rpern, nicht aber im Vakuum ausbreiten k\u00f6nnen. Die Ursache ist immer eine Schallquelle, die eine sich fortpflanzende mechanische Verformung des \u00dcbertragungsmediums bewirkt. Die Schallwirkungen im Ausbreitungsmedium h\u00e4ngen wesentlich von der Wellenform, der Intensit\u00e4t der Quelle und der Art des Mediums ab.
