AirPods 上的主动降噪功能应该可以阻挡背景声音和环境噪音。(Noise Cancellation)无线耳塞使用朝外和朝内的麦克风来检测和抵消不需要的声音。
降噪(Noise Cancellation)功能很容易在支持的AirPods 机型(AirPods models)上激活和使用。但是，在某些情况下，该功能无法按预期工作。我们将介绍降噪(Noise Cancellation)功能出现故障的原因以及将功能恢复正常的六种方法。
注意：(Note:)截至发布本教程时，只有Apple AirPods Pro和AirPods Max支持主动降噪(Active Noise Cancellation)( ANC )。AirPods 3不支持ANC，尽管它在设计方面与AirPods Pro有一些相似之处。因此(Hence)，以下故障排除修复适用于AirPods Pro和AirPods Max。
1. 检查 AirPods 设置
(Noise Cancellation)仅使用一个AirPods时，(AirPods)降噪功能在AirPods Pro上不起作用。您需要在耳朵中同时佩戴（左右）耳塞才能激活降噪(Noise Cancellation)功能。如果您想在一个AirPod上使用(AirPod)降噪(Noise Cancellation)功能，请在 iPhone 或 iPad 的设置菜单中启用该功能。以下是如何做到这一点：
- 打开iPhone/iPad 上的设置应用程序，然后选择(Settings)辅助功能(Accessibility)。
- 在“物理和电机”部分选择AirPods 。
- 使用一个 AirPod(Noise Cancellation with One AirPod)打开降噪功能。
现在，您将能够在一只耳朵中使用AirPod启用(AirPod)降噪功能。(Noise Cancellation)对于单耳有听力障碍或残疾的AirPods用户来说，这是一项出色的辅助功能。
2.重新启用降噪
如果您的 AirPods 无法阻挡背景噪音，请切换到其他噪音控制模式并切换回降噪(Noise Cancellation)模式。您可以直接从 AirPods 切换噪音控制模式。
对于AirPods Pro，将两只AirPods都放在耳朵中，然后按住任一（左侧或右侧）AirPod 上的力度(Force Sensor)传感器(AirPod)。这将启用或激活透明模式(Transparency Mode)。然后，再次按住力传感器(Force Sensor)切换回降噪(Noise Cancellation)模式。
佩戴AirPods Max时，按下耳机上的降噪按钮可在(Noise Control button)降噪(Noise Cancellation)和通透(Transparency)模式之间切换。
您还可以在Apple设备上远程在降噪(Noise Cancellation)和通透(Transparency)模式之间切换AirPods 。将两个AirPods都(AirPods)插入(Plug)耳朵，然后按照以下步骤操作：
(Switch AirPods Noise Cancellation)在 iOS 设备上切换 AirPods 降噪
将AirPods(AirPods)连接到您的 iPhone/iPad 并按照以下步骤操作：
- 前往“设置”(Settings) > “蓝牙(Bluetooth)” ，然后点击 AirPods 旁边的信息图标。
- 点击AirPods 旁边的信息图标。(info icon)
- 在“噪音控制”部分，选择关闭(Off)或透明(Transparency)以关闭 AirPods 的噪音消除功能。
- 等待几秒钟，然后选择降噪(Noise Cancellation)以重新启用降噪功能。
您还可以从设备的控制中心(Control Center)切换 AirPods 的噪音控制模式。
如果您的 iPhone 有刘海，请从屏幕右上角向下滑动。按照相同的步骤打开 iPad 的控制中心(Control Center)。对于带有主(Home)屏幕按钮的 iPhone（和 iPod touch），从屏幕底部边缘向上滑动。
然后，点住音量滑块(volume slider)，点按噪音控制图标(Noise Control icon)，然后选择噪音消除(Noise Cancellation)。
如果噪音消除不起作用，请选择关闭(Off)以禁用噪音控制，然后重新选择噪音消除(Noise Cancellation)。
(Switch AirPods Noise Cancellation)在Mac上(Mac)切换 AirPods 降噪
将 AirPods 连接到 Mac(Connect your AirPods to your Mac)，然后按照以下步骤操作。
- 选择菜单栏上的AirPods 图标(AirPods icon)，然后在您的AirPods下选择(AirPods)降噪(Noise Cancellation)。如果Mac 的菜单栏上没有AirPods图标，请(AirPods)跳至(Jump)步骤 #2 。
- 打开 Mac 的控制中心(Control Center)并展开声音(Sound)菜单。
- 展开AirPods 菜单(AirPods menu)以查看噪音控制模式。选择关(Off)可禁用主动降噪。重新选择降噪(Noise Cancellation)并检查您的 AirPods 现在是否能阻挡背景噪音。
(Switch AirPods Noise Cancellation)在Apple Watch上(Apple Watch)切换 AirPods 降噪
以下是在Apple(Apple) Watch上重新启用AirPods降噪功能的方法：
- 点击音乐播放器右下角的AirPlay 图标。(AirPlay icon)
- 点击关闭(Off)以禁用主动降噪。等待几秒钟，然后点击降噪(Noise Cancellation)以重新启用主动降噪。
3.重新调整 AirPods Pro(Readjust AirPods Pro)以获得良好的贴合度(Good Fit)
当您的 AirPods 牢固地贴合您的耳朵时，它可提供最佳音质和降噪功能。(Noise Cancellation)确保您的 AirPods Pro耳塞牢固舒适地密封耳道。如果您的 AirPods Pro 降噪(Pro Noise Cancellation)功能无法与预先安装的中号耳塞一起正常工作，请尝试使用不同的耳塞。
您会在AirPods (AirPods) Pro包装中找到两个额外的耳塞（小 [S] 和大 [L]） 。在您的AirPods(AirPods)上尝试两个耳塞，并使用最适合的耳塞。将AirPods(AirPods)调整(Adjust)并重新插入耳朵多次，看看是否能获得良好的密封效果。
如果您不确定是否适合，请在 iPhone 上运行“耳塞贴合度测试”。(Ear Tip Fit Test)将两个AirPods都(AirPods)插入(Insert)耳朵，然后按照以下步骤操作：
- 前往“设置”(Settings) > “蓝牙(Bluetooth)” ，然后点击 AirPods 旁边的信息图标。
- 选择耳塞贴合测试(Ear Tip Fit Test)并点击继续(Continue)以继续。
- 在播放测试声音时，轻点“播放”(Play)按钮并将两个AirPods放在耳边。如果左右耳塞都具有良好的密封(Good Seal)效果，请使用耳塞。
- 点击完成(Done)以关闭“耳塞贴合结果”页面。或者，再次点击“播放”按钮(Play button)重新进行测试。
(Noise Cancellation)在每个AirPods上使用相同的耳塞时，(AirPods)降噪功能可能无法正常工作。根据耳垂的结构，您可能需要在两个AirPods上使用不同的耳塞。有关更多信息，请参阅有关选择 AirPods Pro 耳塞的 Apple 支持文档。(Apple Support document on choosing AirPods Pro ear tips)
4. 清洁 AirPods
清洁AirPods不仅会使它们的声音更大，而且还可以解决性能问题并防止长期损坏。但是，要解决降噪(Noise Cancellation)问题，您不必清洁整个AirPods。只需专注于位于(Simply)AirPods Pro顶部的网格。见下图。
网状下方是向外的麦克风，可在降噪(Noise Cancellation)模式下检测并阻挡外部声音。网格上的异物(Foreign)会阻止麦克风过滤环境噪音。这可能是您的 AirPods Pro 降噪(Pro Noise Cancellation)功能无法正常工作的原因。
检查网片表面并用干棉签擦去灰尘、耳垢或碎屑。接下来(Next)，使用软毛刷去除粘在网眼上的顽固污垢或耳垢。不要使用锋利的物体、研磨材料或任何液体溶液——甚至是水来清洁麦克风网。有关更多提示，请参阅Apple 官方清洁 AirPods指南。(Apple’s official guide on cleaning AirPods)
5.更新配对设备
将 iPhone、iPad 或 Mac 的软件更新到最新版本可以修复 AirPods 的声音问题。
前往“设置”(Settings) > “通用(General)” > “软件更新”(Software Update)并安装适用于 iPhone 或 iPad 的最新 iOS 或 iPadOS 版本。
要更新您的 Mac 电脑，请转至系统偏好设置(System Preferences)> 软件更新，然后选择立即更新(Update Now)或立即升级(Upgrade Now)。
如果AirPods 降噪(AirPods Noise Cancellation)功能仅在您的Apple Watch上失败，更新手表的操作系统可能会解决问题。了解如何在(how to update an Apple Watch)有或没有 iPhone 的情况下更新 Apple Watch。
6. 注册AirPods 维修服务(AirPods Service Repair)
据 Apple 称， (According to Apple)2020 年 10 月之前(October 2020)生产的AirPods Pro中有一小部分存在缺陷，可能会出现声音问题。在打电话或在嘈杂的环境中，有故障的设备可能会发出噼啪声或静电声。主动降噪(Noise Cancellation)失败和低音损失是该缺陷的其他显着影响。
请联系 Apple 支持(Contact Apple Support)以验证您的 AirPods Pro是否符合服务计划的条件。更好的(Better)是，访问任何Apple 授权服务提供商(Apple Authorized Service Provider)或Apple Store。
阻挡噪音
更新 AirPods 的固件(Updating your AirPods’ firmware)是另一个值得尝试的故障排除修复程序。固件(Firmware)更新通常附带性能增强和错误修复。如果这不能解决问题，请将您的 AirPods 重置为出厂设置(reset your AirPods to factory settings)，然后将它们重新连接到您的设备。
AirPods Noise Cancellation Not Working? 6 Ways to Fix
Active Noise Cancеllation on your AirPods should block background sounds and ambient noise. The wireless earbuds use both outward-facing and inward-facing miсrophones to deteсt and counter unwanted sounds.
Noise Cancellation is easy to activate and use on supported AirPods models. However, there are instances when the feature fails to work as expected. We’ll cover why Noise Cancellation malfunctions and six ways to restore the feature to normalcy.
Note: As of publishing this tutorial, only the Apple AirPods Pro and AirPods Max support Active Noise Cancellation (ANC). The AirPods 3 doesn’t support ANC even though it bears some semblance with the AirPods Pro design-wise. Hence, the troubleshooting fixes below apply to the AirPods Pro and AirPods Max.
1. Check AirPods Settings
Noise Cancellation won’t work on AirPods Pro when using just one AirPods. You need to have both (left and right) earbuds in your ears to activate Noise Cancellation. If you want to use Noise Cancellation with one AirPod, enable the feature in your iPhone or iPad’s settings menu. Here’s how to do that:
- Open the Settings app on your iPhone/iPad and select Accessibility.
- Select AirPods in the “Physical and Motor” section.
- Toggle on Noise Cancellation with One AirPod.
Now you’ll be able to enable Noise Cancellation with AirPod in one ear. It’s a great accessibility feature for AirPods users with hearing impairment or disability in one ear.
2. Re-Enable Noise Cancellation
If your AirPods do not block background noises, switch to a different noise-control mode and switch back to Noise Cancellation mode. You can switch noise-control modes right from your AirPods.
For AirPods Pro, place both AirPods in your ears, and press and hold the Force Sensor on either (left or right) AirPod. That will enable or activate Transparency Mode. Then, press and hold the Force Sensor again to switch back to Noise Cancellation mode.
When wearing the AirPods Max, press the Noise Control button on the headphones to switch between Noise Cancellation and Transparency modes.
You can also remotely switch your AirPods between Noise Cancellation and Transparency modes on your Apple devices. Plug both AirPods in your ears and follow the steps below:
Switch AirPods Noise Cancellation on iOS Devices
Connect the AirPods to your iPhone/iPad and follow these steps:
- Go to Settings > Bluetooth and tap the info icon next to your AirPods.
- Tap the info icon next to your AirPods.
- In the “Noise Control” section, select Off or Transparency to turn off your AirPods’ noise cancellation.
- Wait for some seconds and select Noise Cancellation to re-enable the noise cancellation feature.
You can also switch your AirPods’ noise control mode from your device’s Control Center.
If your iPhone has a notch, swipe down from the top-right corner of the screen. Follow the same steps to open an iPad’s Control Center. For iPhones with a Home button (and iPod touch), swipe up from the bottom edge of the screen.
Afterward, tap and hold the volume slider, tap the Noise Control icon, and select Noise Cancellation.
If noise cancellation doesn’t work, select Off to disable noise control, and reselect Noise Cancellation.
Switch AirPods Noise Cancellation on Mac
Connect your AirPods to your Mac and follow the steps below.
- Select the AirPods icon on the menu bar and select Noise Cancellation under your AirPods. Jump to step #2 if the AirPods icon isn’t on your Mac’s menu bar.
- Open your Mac’s Control Center and expand the Sound menu.
- Expand the AirPods menu to view the noise control modes. Select Off to disable active noise cancellation. Re-select Noise Cancellation and check if your AirPods now block background noise.
Switch AirPods Noise Cancellation on Apple Watch
Here’s how to re-enable the AirPods noise cancellation feature on an Apple Watch:
- Tap the AirPlay icon in the bottom-right corner of the music player.
- Tap Off to disable active noise cancellation. Wait a few seconds and tap Noise Cancellation to re-enable active noise cancellation.
3. Readjust AirPods Pro for Good Fit
Your AirPods provide the best sound quality and Noise Cancellation when it fits firmly in your ears. Ensure your AirPods Pro ear tips seal your ear canals firmly and comfortably. If your AirPods Pro Noise Cancellation isn’t working correctly with the pre-attached medium-sized ear tips, try different ear tips.
You’ll find two extra ear tips (Small [S] and Large [L]) in your AirPods Pro packaging. Try both ear tips on your AirPods and use whichever provides the best fit. Adjust and reinsert the AirPods in your ears multiple times to see if you can get a good seal.
Run the “Ear Tip Fit Test” on your iPhone if you’re unsure about the fit. Insert both AirPods in your ears and follow the steps below:
- Go to Settings > Bluetooth and tap the info icon next to your AirPods.
- Select Ear Tip Fit Test and tap Continue to proceed.
- Tap the Play button and keep both AirPods in your ears as the test sound plays. Use the ear tips if both left and right earbuds have Good Seal results.
- Tap Done to close the “Ear Tip Fit Results” page. Or, tap the Play button again to redo the test.
Noise Cancellation may not work correctly with the same ear tips on each AirPods. Depending on the structure of your earlobes, you may need to use different ear tips on both AirPods. Refer to this Apple Support document on choosing AirPods Pro ear tips for more information.
4. Clean the AirPods
Not only does cleaning your AirPods make them louder, but it can also fix performance issues and prevent long-term damage. However, to fix Noise Cancellation issues, you don’t have to clean the entire AirPods. Simply focus on the mesh located at the top of the AirPods Pro. See the image below.
Underneath the mesh is the outward-facing microphone that detects and blocks external sounds in Noise Cancellation mode. Foreign materials on the mesh will prevent the microphone from filtering ambient noise. That could be why your AirPods Pro Noise Cancellation isn’t working.
Examine the mesh’s surface and wipe off dust, earwax, or debris with a dry cotton swab. Next, use a soft-bristled brush to remove stubborn grime or earwax stuck on the mesh. Do not use sharp objects, abrasive materials, or any liquid solution—not even water to clean the microphone mesh. Refer to Apple’s official guide on cleaning AirPods for more tips.
5. Update the Paired Device
Updating your iPhone, iPad, or Mac’s software to the latest version can fix AirPods’ sound issues.
Go to Settings > General > Software Update and install the latest iOS or iPadOS version available for your iPhone or iPad.
To update your Mac computer, go to System Preferences > Software Update and select Update Now or Upgrade Now.
If AirPods Noise Cancellation fails only on your Apple Watch, updating the watch’s operating system may fix the issue. Learn how to update an Apple Watch with or without your iPhone.
6. Sign Up for AirPods Service Repair
According to Apple, a small percentage of AirPods Pro manufactured before October 2020 are defective and may experience sound issues. The faulty units may produce crackling or static sounds during phone calls or in loud environments. Failing Active Noise Cancellation and loss of bass are other notable effects of the defect.
Contact Apple Support to verify if your AirPods Pro is eligible for the service program. Better yet, visit any Apple Authorized Service Provider or Apple Store.
Block Out the Noise
Updating your AirPods’ firmware is another troubleshooting fix worth trying. Firmware updates often ship with performance enhancements and bug fixes. If that doesn’t resolve the problem, reset your AirPods to factory settings, and reconnect them to your device.
