Abstract

Se proporcionan sopladores que tienen características de reducción de ruido. Un soplador puede incluir un cuerpo principal que define una ruta de flujo de aire a través del mismo, el cuerpo principal que se extiende entre y define un extremo de entrada y un extremo de salida. El soplador puede incluir además un silenciador de entrada provisto en el extremo de entrada. El silenciador de entrada incluye una pluralidad de orificios de entrada, cada uno de la pluralidad de orificios de entrada incluye una superficie periférica que define una apertura de orificio a través de la misma. Al menos uno de la pluralidad de orificios de entrada incluye además un material amortiguador provisto en la superficie periférica del al menos un orificio de entrada y que define además la apertura de orificio a través del mismo.
