Abstract

A sound management system for a vehicle is provided. The sound management system includes a vehicle window coupled to a vehicle body. The vehicle body defines an interior space of the vehicle. The sound management system also includes a laminate disposed on the vehicle window. The laminate is configured to reduce noise in the interior space of the vehicle.

Claims (34)

1. A sound management system for a vehicle, the sound management system comprising:

a vehicle window coupled to a vehicle body, wherein the vehicle body defines an interior space of the vehicle;

an actively controlled laminate disposed on the vehicle window and configured to generate vibrations and transmit sound to reduce noise in the interior space of the vehicle; the laminate being actively controlled in combination with an exhaust active noise cancellation system; and

a controller coupled to the laminate; the controller receiving a signal indicative of a noise level inside the vehicle;

wherein the controller controls the laminate by:

processing the received signal;

detecting a desirable noise signal and an undesirable noise signal based on the received signal; and

transmitting the undesired noise signal to a vehicle cabin after filtering.

2. The sound management system of claim 1 , wherein the laminate is a passive film that reduces transmission of sound to the interior space of the vehicle.

3. The sound management system of claim 2 , wherein the laminate is applied to the vehicle window through an adhesive.

4. A vehicle comprising:

a vehicle body defining an interior space of the vehicle; and

a sound management system for the vehicle, the sound management system including:

a vehicle window coupled to the vehicle body; and

an actively controlled laminate disposed on the vehicle window and configured to generate vibrations and transmit sound to reduce noise in the interior space of the vehicle; the laminate being actively controlled in combination with an exhaust active noise cancellation system; and

a controller coupled to the laminate; the controller receiving a signal indicative of a noise level inside the vehicle;

wherein the controller controls the laminate by:

processing the received signal;

detecting a desirable noise signal and an undesirable noise signal based on the received signal; and

transmitting the undesired noise signal to a vehicle cabin after filtering.

5. The vehicle of claim 4 , wherein the laminate is a passive film that reduces transmission of sound to the interior space of the vehicle.

6. The vehicle of claim 5 , wherein the laminate is applied to the vehicle window through an adhesive.

7. The sound management system of claim 3 , wherein the laminate is applied to an inner surface of the vehicle window.

8. The sound management system of claim 1 , wherein the laminate comprises a base layer, an intermediate layer, and a cover layer.

9. The sound management system of claim 8 , wherein the base layer is adapted to apply the laminate to the vehicle window.

10. The sound management system of claim 8 , wherein the intermediate layer is adapted to attenuate sound being transmitted by the vehicle window.

11. The sound management system of claim 10 , wherein the intermediate layer comprises one of a sound absorbing or sound reflecting material.

12. The sound management system of claim 8 , wherein the cover layer is adapted to the intermediate layer to provide surface protection.

13. The vehicle of claim 6 , wherein the laminate is applied to an inner surface of the vehicle window.

14. The vehicle of claim 4 , wherein the laminate comprises a base layer, an intermediate layer, and a cover layer.

15. The vehicle of claim 14 , wherein the base layer is adapted to apply the laminate to the vehicle window.

16. The vehicle of claim 14 , wherein the intermediate layer is adapted to attenuate sound being transmitted by the vehicle window.

17. The vehicle of claim 15 , wherein the intermediate layer comprises one of a sound absorbing or sound reflecting material.

18. The vehicle of claim 14 , wherein the cover layer is adapted to the intermediate layer to provide surface protection.
