1 Rubber is an important underwater acoustic material.

2 The acoustic curtain belongs to the porous organic-fiber acoustic material.

3 Isolating-sound and decoupling coating is a important underwater acoustic material and structure, and it is coated the outer surface of the submarine body which is used to support sound press.

4 I'm going to do a lot of acoustic material which I won't able to do with my band and in time, I'm going to bring other musicians out.

5 The acoustic material is an effective measure which could reduce noise and improve acoustic environment.

6 Acoustic material and heat-resisting heat-storing material is filled in the porous inner tube and the housing body.

7 Unfortunately, the beginnings of utterances appear to be particularly unconstrained by either the acoustic material or the linguistic interpretation.

8 In applied acoustics field, the sound absorption measurement of an acoustic material and structure is always an important and basic task.

9 The paper analyzes its two-voice parts and the organization of the acoustic material, and discusses the characteristics of polyphony manifested in the electro-acoustic music.
