Active noise cancellation

Rear Microphone

The active noise cancellation system uses microphones 1 positioned inside the Nissan Murano cabin to detect low-frequency engine booming noise. After identifying this unwanted sound, the system automatically produces a corresponding noise-canceling signal through the vehicle speakers and the woofer, if so equipped. This sound is designed to reduce the perceived engine booming noise and provide a quieter, more comfortable passenger compartment.

NOTE: To help the active noise cancellation system operate correctly, observe the following precautions:

• Do not cover or obstruct any of the speakers or the woofer, if so equipped, because the system relies on these components to produce the noise-canceling sound.
• Do not cover the interior microphones or place objects directly over them, as this may prevent accurate detection of engine booming noise.
• Do not replace, alter, or modify the speakers, including the woofer if so equipped, or any related audio component such as the amplifier. Changes to the audio system may affect active noise cancellation performance.
• Do not install additional sound-deadening materials or make other modifications around the microphones or speakers. Altering these areas may change the acoustic characteristics of the cabin and interfere with proper system operation.

Active sound enhancement

Active sound enhancement reinforces selected existing engine sounds according to engine speed and the selected driving mode. The enhanced sound is reproduced through the Nissan Murano speakers and the woofer, if so equipped, to provide a more noticeable engine sound that reflects the current driving conditions.
