For Honda Accord, the noise is not very loud, and the engine sound is good in mid-size cars, but the Accord is not very sound-proof, so the sound is a bit loud, but at least it is of a medium level.
According to the noise test of the Accord, in the aspect of car silence, the sound insulation and noise reduction level of the new Accord in the middle and low speed driving state can be said to be commendable, especially in the idling state, the noise value in the car is as low as 39.9 dB, far below the standard value. However, when the vehicle speed is gradually increased above 120km/h, the interior noise is close to the standard value.
In addition, Accord is equipped with a similar active noise reduction system, which is officially called ANC active noise reduction system. The enclosed space in the car is like an earphone. ANC system is equipped with three microphones to collect various environmental noises, including engine noise. After computer analysis, the sound waves opposite to these noises are emitted from the speakers in the car to offset the noise to the greatest extent. In addition, the new Accord also adopted its own patented technology-tire air column noise reducer to further control tire noise.
