Claims:We Claim:

1. A method of generating a personalized audio space in a vehicle, the method comprising:
receiving, by a processor of a personalized audio space generation system, a user related information of a user in the vehicle from at least one image sensor associated with each of one or more regions in the vehicle;
determining, by the processor, direction of one or more first directional speakers associated with each of the one or more regions in the vehicle based on the received user related information;
identifying, by the processor, an audio space boundary for each of the one or more regions based on the direction of the one or more first directional speakers of corresponding region of the one or more regions;
rendering, by the processor, a first sound wave of a user selected audio in the determined direction using the one or more first directional speakers associated with one of the one or more regions where the user is seated; and
transmitting, by the processor, a second sound wave corresponding to the first sound wave along the identified audio space boundary of the one of the one or more regions using one or more second directional speakers associated with the one of the one or more regions, wherein the first sound wave and the second sound wave converge at the audio space boundary of the region such that the second sound wave restricts rendering of the first sound wave beyond the audio space boundary of the one of the one or more regions to generate the personalized audio space in the vehicle.

2. The method as claimed in claim 1, wherein the user related information includes a height of the user, a position of the user, material of interior of the vehicle, and acoustic characteristics associated with the material in each of the one or more regions.

3. The method as claimed in claim 1, wherein transmitting the second sound wave corresponding to the first sound wave comprising:
determining the first sound wave associated with the user selected audio via an input source associated with each of the one or more regions in the vehicle, wherein the user selected audio is played via the one or more first directional speakers associated with the one of the one or more regions; and
generating the second sound wave based on the first sound wave of the user selected audio, displacement of the first sound wave in the one of the one or more regions and a specific acoustic impedance for the first sound wave in the one of the one or more regions.

4. The method as claimed in claim 3, wherein the specific acoustic impedance for the first sound wave is determined as product of density and phase velocity of the first sound wave of the user selected audio.

5. The method as claimed in claim 3, wherein the second sound wave comprises amplitude and frequency equivalent to that of the first sound wave.

6. The method as claimed in claim 3, wherein the second sound wave is 180 degrees out of phase with respect to the first sound wave.

7. The method as claimed in claim 1, wherein the first sound wave associated with the user selected audio is determined based on a metadata of the user selected audio stored in a media device connected to the one of one or more input sources configured in the vehicle.

8. The method as claimed in claim 1, wherein the determined direction of the first directional speaker is varied based on the user related information including acoustic characteristics of material of interior of the vehicle.

9. The method as claimed in claim 1, wherein direction of the second directional speaker is varied based on the audio space boundary in the one of the one or more regions.

10. A personalized audio space generation system, the system comprising:
a processor;
a memory, communicatively coupled with the processor, wherein the memory stores processor-executable instructions, which on execution cause the processor to:
receive a user related information of a user in the vehicle from at least one image sensor associated with each of one or more regions in the vehicle;
determine direction of one or more first directional speakers associated with each of the one or more regions in the vehicle based on the received user related information;
identify an audio space boundary for each of the one or more regions based on the direction of the one or more first directional speakers of corresponding region of the one or more regions;
render a first sound wave of a user selected audio in the determined direction using the one or more first directional speakers associated with one of the one or more regions where the user is seated; and
transmit a second sound wave corresponding to the first sound wave along the identified audio space boundary of the one of the one or more regions using one or more second directional speakers associated with the one of the one or more regions, wherein the first sound wave and the second sound wave converge at the audio space boundary of the region such that the second sound wave restricts rendering of the first sound wave beyond the audio space boundary of the one of the one or more regions to generate the personalized audio space in the vehicle.

11. The system as claimed in claim 10, wherein the user related information includes a height of the user, a position of the user, material of interior of the vehicle and acoustic characteristics associated with material of the vehicle in each of the one or more regions.

12. The system as claimed in claim 10, wherein the processor is configured to transmit the second sound wave corresponding to the first sound wave by:
determining the first sound wave associated with the user selected audio via an input source associated with each of the one or more regions in the vehicle, wherein the user selected audio is played via the one or more first directional speakers associated with the one of the one or more regions; and
generating the second sound wave based on the first sound wave of the user selected audio, displacement of the first sound wave in the one of the one or more regions and a specific acoustic impedance for the first sound wave in the one of the one or more regions.
13. The system as claimed in claim 12, wherein the specific acoustic impedance for the first sound wave is determined as product of density and phase velocity of the first sound wave of the user selected audio.

14. The system as claimed in claim 12, wherein the second sound wave comprises amplitude and frequency equivalent to that of the first sound wave.

15. The system as claimed in claim 12, wherein the second sound wave is 180 degrees out of phase with respect to the first sound wave.

16. The system as claimed in claim 10, wherein the first sound wave associated with the user selected audio is determined based on a metadata of the user selected audio stored in a media device connected to the one of one or more input sources configured in the vehicle.

17. The system as claimed in claim 10, wherein the direction of the first directional speaker is varied based on the user related information including acoustic characteristics of material of interior of the vehicle.

18. The system as claimed in claim 10, wherein direction of the second directional speaker is varied based on the audio space boundary in the one of the one or more regions.
