ANC uses a combination of Active Noise Cancellation and Transparency mode. When ANC is on, your AirPods Pro will seamlessly switch between these two modes without any manual intervention from you.
Active Noise Cancellation works by creating sound waves that counteract external noise, effectively silencing unwanted sounds. Transparency mode, on the other hand, allows some outside noise to filter through, so you’re aware of your environment.
- Active Noise Cancellation – Blocks external sound
- Transparency mode – Lets in environmental noise
Here’s how to activate ANC on your AirPods Pro:
- Go to Settings on your iPhone or iPad.
- Select Bluetooth and tap on the “i” icon next to your AirPods Pro.
- Toggle on Adaptive Noise Control.
Your AirPods utilize machine learning algorithms to predict and adapt to noise changes. They gauge the ambient noise levels and shift between modes to provide an optimal listening environment. This means if you step into a noisy street, the ANC will intensify, and as you return to a quieter setting, it will ease, allowing natural sound in without you needing to adjust the settings manually.
Working Principle of Adaptive Noise Control in AirPods
Adaptive Noise Control in your AirPods Pro uses advanced technology to dynamically adjust ambient sound. This ensures an optimal audio experience that responds to your environment.
Digital Signal Processing
Your AirPods Pro contain a powerful Digital Signal Processor (DSP) that is the brain behind Adaptive Noise Control. The DSP continuously analyzes external and internal sound data to determine the appropriate level of noise cancellation in real time.
Microphone Role
Two types of microphones play crucial roles in Adaptive Noise Control:
- External Microphones detect environmental noise before it reaches your ear.
- Internal Microphones listen to sound inside your ear canal to measure what you are actually hearing.
These microphones feed information to the DSP to enable adjustments to the noise cancelling profile.
Feedback and Feedforward Systems
Your AirPods Pro use both feedback and feedforward systems:
- Feedback System: This closed-loop system uses the internal microphones to adjust the noise cancellation based on what you’re currently hearing.
- Feedforward System: This open-loop system relies on external microphones to anticipate noise and preemptively adjust the sound profile before the noise enters your ear.
