HMEC 25-6A / HMEC 25-KAP-2

El juego de intercomunicación reúne dos módulos, es decir el auricular y el micrófono, es una sóla unidad funcional. Estos juegos de intercomunicación HMEC 25-KA/-CA se emplean sobre todo para efectos de comunicación en cabinas de aviones.

￿Como micrófono se emplea un micrófono electreto de alta calidad, polarizado permanentemente. La tensión de abastecimiento necesaria (según ARINC) se toma de la red de a bordo del avión, a través del enchufe de conexión.

￿Como auriculares se emplean los sistemas NoiseGardde Sennheiser. Estos son sistemas de auriculares dinámicos en los cuales, además de la reproducción de una señal de video, se compensa por medios electrónicos el sonido perturbador de baja frecuencia. La compensación de ruido activa funciona según el principio físico según el cual, la sonoridad y la "antisonoridad" se anulan recíprocamente (mediante la oposición de fase en 180˚).

￿La eléctronica de compensación NoiseGardexistente en el auricular requiere su propia alimentación de corriente, que es proporcionada por el bloque de alimen- tación, unido firmemente al cable del auricular (ver la ilustración p. 38).

De tal forma se logra una comunicación sin perturbaciones, sin tener que regular el sonido a un volumen tan alto como para poder suprimir los ruidos medioambientales.
