What is the decibel level of the interior noise in the X-Trail?

GB-1495-2002 stipulates that the exterior noise limit for small cars (M1 category vehicles) is 74dB(A) (decibels). Currently, there is no mandatory standard for interior noise in passenger cars, although there is a standard for interior noise in buses, "GB/T2598". Automotive noise is divided into interior noise and exterior noise. The former affects the comfort of the occupants inside the vehicle, while the latter causes noise pollution to the external environment. Sources of automotive noise include engine noise, wind resistance noise, air conditioning noise, tire noise, drivetrain vibration, body twisting and vibration, and braking noise. The interior noise level in the X-Trail is below 60 decibels, which falls within the range of normal conversation sounds (40-60 decibels). GB-1495-2002 stipulates that the exterior noise limit for small cars (M1 category vehicles) is 74dB(A) (decibels). However, there is currently no mandatory standard for interior noise in passenger cars, as interior noise is only heard by the occupants inside the vehicle, and comfort is subjective.
I've driven several X-Trails from different years and found that cabin noise really depends on conditions. At 60 km/h in the city, the noise level is around 60 decibels, similar to conversational speech. On highways at 100 km/h, it rises to about 67 decibels, comparable to medium TV volume. Many factors affect this: rough roads increase noise, worn tires add a humming sound, and engine or wind resistance contributes too. Newer high-trim models have better sound insulation, reducing noise below 65 decibels. I recommend testing with a smartphone decibel app yourself, as it varies by vehicle. Excessive noise might indicate aging seals - regular maintenance can help. Overall, the X-Trail's noise control is above average for its class. On long trips, remember to take breaks to reduce fatigue.
As someone who frequently researches SUVs, I've compared the interior noise data of the Nissan X-Trail. Under standard conditions: approximately 45 decibels at idle, 63 decibels at 60km/h, and reaching 70 decibels at highway speeds of 120km/h. Compared to other popular models like the Toyota RAV4, the RAV4 is slightly quieter at highway speeds, but the X-Trail's active noise cancellation technology has improved the experience in newer models. The main sources of noise are engine vibration and tire noise, so choosing quiet tires can reduce the noise by a few decibels. When buying a car, don't just look at the specs—be sure to test drive on different road sections to experience it firsthand. Additionally, clutter in the car can increase noise, so keeping the cabin tidy helps. Overall, the X-Trail's noise levels are reasonable and suitable for family daily use. On long drives, remember to lower the music volume to avoid distractions.
