Pass-through element for a motor vehicle front of dash system

1. A pass-through element for a motor vehicle front of dash system comprising:

a body portion having an outer edge that surrounds a central web;

a conductor pass-through member provided in the central web; and

a sound enhancement element provided in the central web adjacent the conductor pass-through member, the sound enhancement element extending from a first end projecting from the central web in a first direction to a second end projecting from the central web in a second direction that is distinct from the first direction through an intermediate portion having a contoured surface, the sound enhancement element being configured and disposed to condition and conduct motor vehicle engine sound from an engine compartment to a passenger compartment through the motor vehicle front of dash system.

2. The pass-through element according to claim 1 , wherein the sound enhancement element includes a first end projecting from the central web in a first direction and a second end projecting from the central web in a second direction that is distinct from the first direction.

3. The pass-through element according to claim 2 , wherein the first and second directions extend along a common axis.

4. The pass-through element according to claim 1 , wherein the contoured surface defines an acoustically tuned element.

5. The pass-through element according to claim 4 , wherein the acoustically tuned element defines an acoustic filter.

6. The pass-through element according to claim 1 , wherein the first end includes a first opening having a first dimension and the second end includes a second opening having a second dimension that is substantially similar to the first dimension.

7. The pass-through element according to claim 1 , wherein the contoured surface comprises a complex curvilinear profile.

8. The pass-through element according to claim 1 , wherein the outer edge includes a groove that defines first and second flange elements.

9. The pass-through element according to claim 1 , wherein the conductor pass-through member and the sound enhancement element are materially integrally formed with the central web.

10. The pass-through element according to claim 1 further comprising: a diaphragm arranged in the sound enhancement element, the diaphragm being configured and disposed to tune motor vehicle engine sound passing from the engine compartment to the passenger compartment.

11. A motor vehicle comprising:

a body including an engine compartment, and a passenger compartment, the engine compartment including a sound enhancer;

a motor vehicle front of dash system separating the engine compartment from the passenger compartment, the front of dash panel including one or more openings; and

a pass-through element arranged in one of the one or more openings in the front of dash system, the pass-through element comprising:

a body portion having an outer edge that surrounds a central web;

a conductor pass-through member provided in the central web; and

a sound enhancement element provided in the central web adjacent the conductor pass-through member, the sound enhancement element extending from a first end projecting from the central web in a first direction to a second end projecting from the central web in a second direction that is distinct from the first direction through an intermediate portion having a contoured surface and being coupled to the sound enhancer, the sound enhancement element being configured and disposed to condition and conduct motor vehicle engine sound from an engine compartment to a passenger compartment through the motor vehicle front of dash system.

12. The motor vehicle according to claim 11 , wherein the sound enhancement element includes a first end projecting from the central web in a first direction and a second end projecting from the central web in a second direction that is distinct from the first direction.

13. The motor vehicle according to claim 11 , wherein in contoured surface defines an acoustically tuned element.

14. The motor vehicle according to claim 13 , wherein the acoustically tuned element defines an acoustic filter.

15. The motor vehicle according to claim 11 , wherein first end includes a first opening having a first dimension and the second end includes a second opening having a second dimension that is substantially similar to the first dimension.

16. The motor vehicle according to claim 15 , wherein the second dimension is larger than the first dimension.

17. The motor vehicle according to claim 11 , wherein the outer edge includes a groove that defines first and second flange elements.

18. The motor vehicle according to claim 11 , further comprising: a diaphragm arranged in the sound enhancement element, the diaphragm being configured and disposed to tune motor vehicle engine sound passing from the engine compartment to the passenger compartment.
