Objective:
Research for potential material which could be used in MSXIV to reduce noise.
...
- Where in the car could generate loud sound?
- Rationale: To figure out where we should use noise cancellation; understand limitations in space and shape.
- What materials are used in car industry?
- Rationale: To figure out the safest way which is modifying existing products in the industry.
- What materials are used in the architecture industry?
- Rationals: To find a way which may be missed by the normal car industry
- Research on MSXIV
- Understanding if the material is practical
- Validation
- 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

Tires:triple-sealed doors; side glass
Sealed-off pillars
acoustic spray foam
RQ#3: What materials are used in the architecture industry?
Architecture sound control relies more on heavier materials and structures.
Acoustic sealing(around 25)
Could be an extra addition to fill in some holes which air can move caused by wires.https://www.youtube.com/watch?v=eHQbEsCgWt4
Acoustic spray foam:
Problem: There are website saying spray foam would do little work.
a special heat and noise blocking product(current top)
Problem: its description says it could block the low-frequency sounds from combustion engines; however, in MSXIV, the sound created by electrical motors might be high frequency just like all the other electric cars.
Acoustic laminated glass/side glass
