Is the Active Noise Cancellation in Accord Turned On by Default?
2 Answers
The active noise cancellation function in Accord is turned on by default. Below is an introduction to the methods and principles of automotive noise reduction: Methods of automotive noise reduction: In design, minimize the noise radiation area by removing unnecessary metal panels. Apply a layer of damping coating on metal structures to suppress structural vibrations and reduce noise. Principles of noise reduction: Use in-car microphones to collect noise samples. After analysis and processing by the system, the audio system generates a signal with the same frequency and amplitude as the noise but with a 180-degree phase difference. When the noise signal and the noise-canceling signal (from the audio system) intersect and overlap, they cancel each other out, achieving noise reduction and creating a quieter in-car environment.
After driving an Accord for several years, I've noticed that the active noise cancellation is enabled by default when starting the vehicle, requiring no manual activation. The system uses microphones in the audio system to capture noise and generates real-time inverse sound waves to cancel out engine and road noise. Personally, I find this feature particularly useful on highways or bumpy roads, as it significantly quiets the cabin and reduces fatigue. To turn it off, you'd need to navigate to the settings menu in the vehicle's central console, but I've hardly ever done so—it's just one less thing to worry about. Some audiophiles or those who modify their sound systems might recommend disabling it to avoid interference with sound quality, but the factory default setting keeps it on for safety and practicality. During routine maintenance, I also check the system's status to ensure it's functioning properly, as cabin quietness greatly impacts driving comfort.
