Beschreibung
Zusammenfassung:	The sound absorbing structure comprises a sound absorbing member (6), an air layer (7) formed in the rear of the sound absorbing member, and a resonant sound absorbing structure including a slit and formed in the rear of the sound absorbing member. The sound absorbing member is a surface plate covering the air layer and resonant sound absorbing structure. The sound absorbing member is shaped as a plate or plane. A sound absorbing structure comprising a sound absorbing member, a air layer, and a resonant sound absorbing structure. The air layer is formed in the rear of the sound absorbing member. The resonant sound absorbing structure includes a slit and is formed in the rear of the sound absorbing member. The sound absorbing member is a surface plate covering the rear air layer and the resonant sound absorbing structure, and the sound absorbing member is shaped in one of a plate and plane.
