Sound management system for a vehicle
View Patent ↗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.
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.
