초록

Honeycomb noise attenuation sandwich panels and method of construction having a cellular core positioned between and bonded to two facing sheets. One facing sheet is perforated and the other imperforate. A thin sheet of porous fibrous felt or fabric is bonded to the perforated sheet. The core cells communicate with the atmosphere through the perforated sheet and the pores of the fibrous sheet.
