What is the noise level in decibels for the Elantra at 120 km/h?
2 Answers
The interior noise of the Elantra at 120 km/h is below 60 decibels. There is currently no mandatory standard for interior noise, but the Elantra's sound insulation details are relatively well done. Acceptable standard for interior noise: If a car reaches a speed of 120 km/h, the interior noise should be below 69 decibels to be considered acceptable. When a car is in operation, it generates noise, causing noise pollution both inside and outside the vehicle. Generally, interior noise mainly comes from engine noise, road noise, tire noise, wind noise, resonance noise, and other sources. Hazards of car noise: Car noise not only causes sound pollution, affecting living and working environments, but also poses health risks. Noise levels above 60 decibels are considered noisy, 70 decibels begin to damage auditory nerves, and 90 decibels can cause hearing impairment. When abnormal noises occur inside the car, it should be promptly inspected and repaired to avoid affecting normal driving and compromising road safety.
When driving the Elantra at 120 km/h, the interior noise typically reaches around 70 decibels, similar to the level of urban traffic noise. Personally, I find wind noise the most noticeable, especially at high speeds with strong winds, where the wind shear sound is quite loud. Tire noise also becomes prominent, and it gets even louder with worn tires or on uneven road surfaces. Excessive noise can easily lead to driver fatigue, so I usually recommend regularly checking the car's sealing strips and suspension system. Using quiet tires can make a noticeable difference. Additionally, closing the windows slightly reduces noise, but the effect is limited when using the air conditioning or playing music to mask it. It's best to develop habits like keeping water handy or taking breaks during long drives. Overall, the Elantra is an economical car with average noise control—it's not super quiet, but it's acceptable for daily highway driving.
