In the current highly competitive automotive industry, especially in the B-class car segment, major car brands have launched models with rich configuration, excellent appearance, excellent handling and good cost performance.
However, the variety of models and car companies in the commercial marketing of the professional terminology is dazzling, many consumers often fall into the "a meal of operation as fierce as a tiger, fixed eyes on the pestle in situ" embarrassing situation.
So, for ordinary consumers, in addition to the car's exterior design, configuration, interior, powertrain and other traditional product strength, is there any other dimension to measure whether a car's product power is excellent?
The answer is sound insulation and tranquility. A luxury car, only has excellent mechanical quality is not enough, but also need to provide drivers and occupants with a quiet and comfortable driving space, so that they can relax and rest for a while when they are tired, and when they are energetic, they can chat with their companions to provide more advanced travel quality.
In this regard, Tianlai is very outstanding, and has been crowned by consumers as a "comfortable sofa", which is evident in its tranquility and comfort. Tianlai has excellent product strength in terms of power, configuration and other hardware, but also provides a very good sound insulation effect.
With its comprehensive product strength and unique comfortable and quiet labels, Tianlai has become the most popular mid-size sedan in the domestic market, and its sales volume ranks at the forefront of the market segment. According to the data, the seventh generation of Tianlai continued the previous upward momentum, with cumulative sales of 40,686 units from January to March, an increase of 14% year-on-year, setting a record for the best sales in the first quarter.

"The performance of Tianlai can only be said to be unquestionable." The purchase of Tianlai has been less than half a year, and the owner Xiao Wu is very satisfied with his car.
As an ordinary white-collar worker, Xiao Wu can only say that he knows a little about cars, he buys cars more out of the needs of life and work, in a number of German, Japanese, American, independent brand models of the same level, Xiao Wu finally chose Tianlai, "good appearance, good name, suitable price, driving experience is the best among the candidate models."
"My driving habits are not very good, running a small 10,000 kilometers, half of the highway and half of the county and township roads, the overall fuel consumption is 7.6, and the minimum can reach 4.2 when running high speed." In this small half year of driving, Tianlai has two points that Xiao Wu expected, "The other is comfort and silence performance." Tianlai deserves the name of 'comfortable sofa', even if you drive a long-distance high-speed will not feel uncomfortable. My parents get motion sickness, but I haven't fainted in my nature, and they feedback it's because the seats are comfortable and the car is muted."
In fact, in addition to other visible and tangible products, Tianlai's performance in comfort and tranquility can be said to conquer almost all car owners, and its characteristics are also well-known in the car circle.

Recently, Tianlai's quiet advantage has once again been recognized by authoritative institutions, and it has been awarded the "Quiet Star" certification certificate issued by the China Automobile Advantech Certification Center, becoming the first model in the joint venture B-class sedan to receive this honor. The certification evaluation system is more stringent and more dimensional than the national standard.
In the measurement of vehicle sound insulation, the sound insulation coefficients of the main passenger seat of Tianlai are 3090 and 3094 respectively (the coefficient ≥ 3000 can obtain A-level evaluation, the highest level). In the vehicle noise transfer function test, the front cabin, exhaust pipe and other parts of Tianlai were measured with coefficients of 3061 and 3094 respectively (the coefficient ≤ 3100 can be evaluated A, the most advanced).
It is worth mentioning that the 2021 Tianlai 2.0L XL Comfort Edition participating in the trial is the sub-low version of the official guidance of 187,800, and the relevant tests of ANC active noise reduction system, ATR active torque tie rod system and other functions were not opened in the test. This also means that if you choose a higher model or turn on functions such as noise reduction system, Tianlai will also have better performance.
In the above certification evaluation, Tianlai showed a very high level, and in the case of almost "self-binding hands", it still got better results than other Japanese and German brands of the same level. With strength deduction, what is the reason why 100 points is because the highest standard is only 100 points.
In addition, in September 2021, Tianlai also won the "King of Tranquility" in the 2021 China Mass Production Vehicle Performance Competition CCPC Professional Station Sound Insulation and Noise Reduction Competition. In addition to leading competitors, the quiet results also surpassed BMW, Mercedes-Benz, Volvo and many other luxury brands and even new energy models that participated in the same field.
How does nissan do it?
Excellent sound insulation is Nissan's housekeeper's magic weapon, and on this extraordinary technological flow road, tianlai has always been imitated, but never surpassed.
The reason for this is that on the one hand, Nissan pays more attention to the sound insulation performance of the Tianlai car system, and at the beginning of the product planning, it has set a higher sound insulation performance target for Tianlai, and achieved it through scientific methods and mature research and development systems.
In addition, Dongfeng Nissan will also optimize the design of each component to improve the NVH performance of the vehicle, and predict/verify the achievement status of the performance target through various computer simulations and actual vehicle tests, so as to ensure that the final mass production model can meet or even exceed the performance target originally set.

In addition to the scientific nature of the product manufacturing system, Dongfeng Nissan is also very sincere in the concept of product creation, adheres to customer firstism, and creates the best product experience at any cost. For example, the front windshield and side doors and windows of all models of Tianlai use high-strength double-layer soundproof glass, which is rare in the same class. In many places on the body, sound insulation materials have also been added, such as the use of double-layer sound-absorbing cotton materials on the top, bottom, front circumference, etc. of the vehicle, and the sheet metal parts that are prone to vibration are added to damping pads to suppress vibration. With the blessing of these soundproof materials, the occupants sit in the car and can be isolated from the outside world to the greatest extent.
Not only in terms of passive noise reduction, Dongfeng Nissan in order to give tianlai drivers a better experience on the road, but also equipped with ANC active noise reduction system, ATR active torque tie rod system, through the full-dimensional noise reduction to ensure the high quietness of the car. The Multi-Layer ergonomic seat and BOSE high-quality audio can create an immersive travel experience for users, bringing a more comfortable and enjoyable journey.
It is worth mentioning that the scientific vehicle sound insulation engineering method is the only way for car companies to reduce the noise in the car and improve the tranquility of driving, and the principle of "customer first, product first" is an important factor for Tianlai to stand out in the competition.

In addition, in general, the development cycle of the car is relatively limited, and to achieve a high vehicle sound insulation design goal is a long span of engineering, in which the adjustment of various details is enough to make the engineer gray hair, then the mature collaborative research and development system within the car company, the accumulation of experience and data brought by the perennial best-selling market of the model plays an important role in the middle.
Since its listing in 1988, the Tianlai car series has gone through 7 generations of models in 33 years, each generation has been optimized on the basis of the past, and the accumulation of experience in data accumulation, problem optimization, detail handling, etc., is unmatched by most competing models.
Just as the so-called one step is fast and fast, the natural sound of mastering the technical advantages will continue to lead, providing comfortable and quiet cockpit space for every user, so that consumers can continue to improve their quality of life while upgrading their consumption.
