Acoustic plan for wooden grille ceiling in dining space

<p>During peak hours in the restaurant, customer conversations are superimposed with the sound of clinking cups and plates, and the hard ceiling causes the reverberation time to be too long. The back of the wooden grille ceiling is pasted with black sound-absorbing cotton, and the NRC is about 0.85. </p><p>The wooden grille is coordinated with the dining chairs and green plants, and the ring chandelier is embedded in the ceiling without damaging the acoustic surface. During renovation, the hanging area is calculated based on the restaurant area, which usually accounts for 70% of the suspended ceiling, and the smoke exhaust and air-conditioning channels in the back kitchen are retained. </p>
