In our daily lives, cars have become an indispensable means of transportation. However, over time, many car owners will find themselves getting louder and louder in their cars. This not only affects the comfort of driving, but can also have an impact on the health of the driver and passengers. So, how to solve the problem of interior noise? A senior car mechanic gave a simple way to make the car almost silent when running at high speeds of 120 yards.
First, we need to understand where the noise in the car comes from. Most interior noise is caused by wind noise, tire noise, and mechanical noise. Especially on highways, wind noise and tire noise become more noticeable as the speed increases. To solve this problem, we can reduce the noise by making some simple modifications and adjustments to the vehicle.
For wind noise, we can optimize the appearance of the vehicle. For example, replacing the exterior parts of the body with more streamlined parts and reducing the gaps in the body can effectively reduce wind resistance and noise. In addition, installing door seals can also effectively reduce door gaps and reduce wind noise.
For tire noise, we can choose tires that are quieter. When changing tires, choosing those with quiet properties can effectively reduce tire noise. In addition, adjusting the tire pressure can also have a certain noise reduction effect.
In addition to the above two methods, we can further reduce the noise in the car by adding sound insulation materials. Adding soundproofing materials to the engine compartment, doors, and trunk of a vehicle can effectively isolate noise and improve driving comfort.
To sum up, solving the problem of noise in the car is not complicated. By making some simple modifications and adjustments to the vehicle, we can effectively reduce the noise in the car and improve the comfort of driving. I hope this simple method can help the majority of car owners.
Why does it feel like the car is running backwards when I park?
In our daily life, there are times when we park and feel as if the car is running backwards. This is actually an interesting phenomenon, so let's dive into the reasons for this.
First of all, we need to understand that this feeling does not arise because the vehicle is actually going backwards, but due to a combination of physical and psychological effects. Chief among them is the influence of the reference. When we anchor ourselves to the car and use the car as a reference, we feel that the scenery around us is moving backwards. This is because we are stationary relative to the vehicle, which is moving forward with respect to the surrounding scenery. However, when we step out of the car and use the ground as a reference, we will find that the vehicle is actually stationary.
In addition, the generation of this feeling is also related to our psychological expectations. When we drive forward, the brain has become accustomed to the feeling of the vehicle moving forward. When the vehicle stops, the brain still briefly thinks that the vehicle is moving forward, which creates the illusion that the vehicle is moving backwards.
In addition to psychological and physical factors, this feeling can also be influenced by some physiological factors. For example, when we stop a car, the body will continue to move forward due to inertia, which may cause a certain difference between the signals received by the brain and the actual situation.
To sum up, the phenomenon of feeling that the car is running backwards when parking is due to a combination of factors. These factors include the influence of the referent, psychological expectations, and physiological inertia. Understanding these factors helps us better understand the world around us and improve our perception and judgment skills.
