a first material, having sound attenuating characteristics, shaped to cover over an ear of a user;
at least one aperture formed in the first material; and
a second material positioned over the aperture, wherein the second material is positioned outside the first material.
2. The device of claim 1 , wherein the second material has sound attenuating characteristics that are different from the sound attenuating characteristics of the first material.
3. The device of claim 1 , wherein the first material forms a portion of a body of the hearing protection device.
4. The device of claim 1 , wherein a third material with sound attenuating characteristics is provided inside of the first material.
5. The device of claim 4 , wherein the third material has sound attenuating characteristics that are different from the sound attenuating characteristics of the first material.
6. The device of claim 4 , wherein the third material has sound attenuating characteristics that are different from sound attenuating characteristics of the second material.
7. The device of claim 1 , wherein the second material is a thin film material or membrane.
8. The device of claim 4 , wherein the third material is a foam material.
9. A hearing protection device, comprising:
a first material, having sound attenuating characteristics, and shaped, on a first side, to cover over an ear of a user;
at least one aperture formed in the first material;
a second material, having sound attenuating characteristics, positioned over the aperture; and
a third material comprising foam, having sound attenuating characteristics, positioned inside of the first material.
10. The device of claim 9 , wherein the device includes a weight attached to the second material and positioned over the aperture.
11. The device of claim 9 , wherein the device includes a weight attached to the second material and positioned between the third material and the second material.
12. The device of claim 10 , wherein the weight is removable from the second material.
13. The device of claim 9 , wherein the device includes multiple apertures formed in the first material and wherein at least two of the apertures have different diameters.
14. The device of claim 9 , wherein the device includes multiple apertures formed in the first material and wherein the apertures are formed between the second material and another material.
15. The device of claim 14 , wherein the other material is the third material.
16. A hearing protective device, comprising:
an ear covering body shaped on a first side to cover an ear of a user, and comprising a first material having sound attenuating characteristics;
an aperture in the first material;
a second material having sound attenuating characteristics and positioned over the aperture; and
a third material having sound attenuating characteristics and positioned inside the first material;
wherein the third material comprises foam that spans the aperture.
17. The device of claim 16 , wherein the second material is a thin film material or membrane.
18. The device of claim 17 , wherein the second material is positioned outside the first material.
19. The device of claim 17 , further comprising a weight attached to the second material and positioned over the aperture.
20. The device of claim 19 , wherein the weight is removable from the second material.
