Abstract

An electric heater (40) for integration into an acoustic panel (20) having sound-penetrating pores (30) communicating with a sound-canceling medium. The heater (40) includes an electrically conductive layer (53) with resistance-setting apertures (63) filled with sealant (73). Openings (83), which contribute to the sound-penetrating pores (30), extend through the sealant-filled apertures (63). The acoustic panel (20) can be assimilated into an aircraft component, such as a nacelle inlet lip, which requires both noise-reducing and ice-protecting features.
