2. The acoustic system of claim 1 , wherein: the plurality of wall-mounted polyester shells of a first type each have a first static value of airflow resistance, and the plurality of wall-mounted polyester shells of a second type each have a second static value of airflow resistance that is greater than the first static value.

3. The acoustic system of claim 2 , wherein the second static value is greater than about 5,000 rayls.

4. The acoustic system of claim 3 , wherein the first static value is between 500 and 600 rayls.

5. The acoustic system of claim 1 , further comprising:

a plurality of wall-mounted sections of a third type, each including (i) a sound generating device, and (ii) a polyester shell of a third type positioned over the sound generating device, the polyester shells of a third type being configured to be mounted on the interior surface of the building and cooperate with the plurality of wall-mounted polyester shells of a first type and the plurality of wall-mounted polyester shells of a second type to define the pattern on the interior surface,

wherein each of the plurality of wall-mounted polyester shells of a third type are configured to permit sound waves generated by their respective sound generating device to pass through to a space beyond the respective section of a third type.

6. The acoustic system of claim 1 , wherein each polyester shell comprises non-woven polyester fibers.

7. The acoustic system of claim 1 , wherein each polyester shell includes a front surface having a visible geometric pattern.

8. The acoustic system of claim 7 , wherein the visible geometric pattern includes an embossed pattern.

9. The acoustic system of claim 1 , wherein each polyester shell includes a front surface having an aesthetic pattern.

10. The acoustic system of claim 1 , wherein the each of the plurality of wall-mounted sections of a second type each includes a substrate configured to be positioned in a cavity defined in their respective polyester shell of a second type.

11. The acoustic system of claim 1 , wherein each of the plurality of wall-mounted polyester shells of a second type includes a cavity that defines an air pocket.

12. An acoustic system, comprising:

a plurality of wall-mounted sections of a first type, each being configured to be mounted on an interior surface of a building, and each of the plurality of wall-mounted sections of a first type including: (i) a sound absorptive substrate, and (ii) a polyester shell of a first type positioned over the sound absorptive substrate, and

a plurality of wall-mounted sections of a second type, each being configured to be acoustically coupled to one of the plurality of wall-mounted sections of a first type and mounted on the interior surface of the building, each of the plurality of wall-mounted section of a second type including a polyester shell of a second type,

wherein of the plurality of wall-mounted sections of a second type are one of (i) a reflective section that is configured to reflect sound waves or (ii) an acoustically transparent section that is configured to permit the passage of sound waves, and

wherein the plurality of wall-mounted sections of a first type and the plurality of wall-mounted sections of a second type are configured to be peripherally adjacent so as to define a pattern on the interior surface of the building.

13. The acoustic system of claim 12 , wherein each of the sections of a second type that are reflective sections include a sound reflective substrate positioned in the polyester shell of a second type.

14. The acoustic system of claim 12 , wherein:

the polyester shell of a first type has a first static value of airflow resistance, and

the polyester shell of a second type has a second static value of airflow resistance that is greater than the first static value.
