Claims:We claim:

1. A system 100 for attenuating sound produced by a vehicle, the system 100 comprising:
a navigation device 101 associated with the vehicle for determining location details of the vehicle;
a sound reduction unit 102 provisioned in an exhaust assembly 103 of the vehicle; and
an Electronic Control Unit (ECU) 104 of the vehicle communicatively coupled to the navigation device 101 and the sound reduction unit 102, the ECU 104 is configured to:
detect a sound reduction location, by comparing the location details with a pre-defined location data; and
operate the sound reduction unit 102, to attenuate sound produced by the vehicle when the sound reduction location is detected.

2. The system 100 as claimed in claim 1, wherein a location is identified as the sound reduction location when the location details corresponds with at least one location in the pre-defined location data.

3. The system 100 as claimed in claim 1, wherein a location is identified as the sound reduction location when the location details corresponds with at least one location in the pre-defined location data, and change in illumination level of light around the vehicle is beyond a pre-defined threshold illumination level.

4. The system 100 as claimed in claim 3 further comprises a light sensor 105 mounted on the vehicle and communicatively coupled with the ECU 104, wherein the light sensor 105 is configured to sense change in the illumination level of light around the vehicle.

5. The system 100 as claimed in claim 1, wherein a location is identified as the sound reduction location when the location details corresponds with at least one location in the pre-defined location data and based on pre-defined time.

6. The system 100 as claimed in claim 1 further comprises a timer 106 communicatively coupled with the ECU 104 to determine current time.
7. The system 100 as claimed in claim 1, wherein the sound reduction unit 102 comprises a plurality of sound filters 107 rotatably mounted in the exhaust assembly 103 of the vehicle.

8. The system 100 as claimed in claim 7, wherein the ECU 104 is configured to selectively align at least one sound filter of the plurality of sound filters 107 with exhaust path 108 in the exhaust assembly 103.

9. The system 100 as claimed in claim 8, wherein each of the plurality of sound filters 107 is configured to attenuate sound to different levels.

10. The system 100 as claimed in claim 7, wherein the sound reduction unit 102 further comprises:
a support member 109 comprising a plurality of provisions 110, rotatably mounted in the exhaust assembly 103, wherein, each of the plurality of the provisions 110 is configured to accommodate at least one sound filter of the plurality of sound filters 107; and
an actuator 111 coupled to the support member 109, wherein the actuator 111 is operable by the ECU 104, to rotate the support member 109.

11. The system 100 as claimed in claim 1 further comprises a microphone 112 communicatively coupled with the ECU 104, the microphone 112 is positioned at an outlet portion of the exhaust path 108 to measure intensity of sound at the outlet of the exhaust path 108.

12. The system 100 as claimed in claim 11, wherein the ECU 104 is configured to:
compare, the intensity of sound measured by the microphone 112 with a pre-defined sound data; and
regulate, the sound reduction unit 102 based on the comparison.

13. A method for attenuating sound produced by a vehicle, the method comprising:
determining, by a navigation device 101, location details of the vehicle;
detecting, by an Electronic Control Unit (ECU) 104, a sound reduction location, by comparing the location details with a pre-defined location data; and
operating, by the ECU 104, a sound reduction unit 102 to attenuate sound produced by the vehicle when the sound reduction location is detected.

14. The method as claimed in claim 13 further comprises:
sensing, by a light sensor 105, change in illumination level of light around the vehicle;
identifying, by the ECU 104, the sound reduction location based on at least one of the change in the illumination level beyond a pre-defined threshold illumination level and when the determined location details corresponds with at least one location in the pre-defined location data.

15. The method as claimed in claim 13 further comprises:
determining, by the ECU 104, time information from a timer 106;
identifying, by the ECU 104, the sound reduction location based on the time information corresponding to a pre-defined time and when the determined location details corresponds with at least one location in the pre-defined location data.

16. The method as claimed in claim 13 further comprises:
measuring, by a microphone 112, intensity of sound at outlet of an exhaust path 108;
comparing, by the ECU 104, the intensity of sound measured by the microphone 112 with a pre-defined sound data; and
regulating, by the ECU 104, the sound reduction unit 102 based on the comparison.

17. A vehicle comprising a system 100 as claimed in claim 1.
