Objective:

Research for potential material which could be used in MSXIV to reduce noise.

...

1. Where in the car could generate loud sound?
   1. Rationale: To figure out where we should use noise cancellation; understand limitations in space and shape.
2. What materials are used in car industry?
   1. Rationale: To figure out the safest way which is modifying existing products in the industry.
3. What materials are used in the architecture industry?
   1. Rationals: To find a way which may be missed by the normal car industry
4. Research on MSXIV
   1. Understanding if the material is practical 
5. Validation
   1. Conventional noise-canceling methods include thick insulation or specialized tires to minimize noise from driving over rough roads or uneven pavement. But these fixes can increase vehicle weight and drive down fuel efficiency.https://www.theverge.com/2019/1/9/18175748/bose-noise-canceling-system-car-ces-2019
      1. How to avoid that?

From the engine: high pitched tonal

From wind

From tire

RQ#2: What materials are used in car industry?https://cars.usnews.com/cars-trucks/the-quietest-cars

2019 Ram 1500: better aerodynamics; Wind is directed away from the front wipers, resulting in less annoying “whirring” sounds that could enter the cabin.

2020 Lincoln Navigator: laminated front and side glass&active noise cancellation
