Thermal-acoustic section (436) for an aircraft (10) for reducing noise along an acoustic path (22) produced from an acoustic source (16) is provided herein. The thermal-acoustic section (436) comprises a plurality of juxtaposed porous layers (400) forming a thermal-acoustic stack (447) that has a first outermost portion (474), a second outermost portion (476) and a central portion (478). The thermal-acoustic stack has a gradually deecreasing characteristic acoustic impedance from the first outermost portion to the central portion and a gradually increasing characteristic acoustic impedance from the central portion to the second outermost portion, to promote transmission loss of the transmitted portion of the noise through the thermal-acoustic stack.
