Zusammenfassung:	Described herein are acoustical panels, comprising: a substrate; a non-woven veil having an airflow resistance of greater than 45 mks rayls, comprising: from about 20 wt.% to about 60 wt.% glass fibers; from about 40 wt.% to about 80 wt.% of a filler; and from about 110 dry g/m2 to about 135 dry g/m2 of a coating. Methods of making and using the panels are also described. Se describen en la presente paneles acústicos, que comprenden: un sustrato; un velo no tejido que tiene una resistencia al flujo de aire de más de 45 mks rayls, que comprende: de aproximadamente 20 % en peso a aproximadamente 60 % en peso de fibras de vidrio; de aproximadamente 40 % en peso a aproximadamente 80 % en peso de un agente de relleno; y de aproximadamente 110 g secos/m2 a aproximadamente 135 g secos/m2 de un revestimiento. También se describen métodos de fabricación y uso de los panales.
