To make your iPhone's hearing louder, you can follow the steps below:
1. Adjust the volume: Increase the volume of your iPhone by pressing the volume up button on the upper left side of the device. Alternatively, you can enable the volume slider in the Control Center by swiping down from the top right corner of the screen on iPhone X or newer, or up from the bottom on iPhone 8 or older.
2. Increase call volume: During a phone call, you can increase the volume by using the volume up button or by directly tapping the speaker icon on the call screen. This will enhance the sound during the call and make it louder.
3. Enable Phone Noise Cancellation: In the iPhone settings, go to "Settings" > "Accessibility" > "Audio/Visual" > "Phone Noise Cancellation." Ensure that this feature is turned off as it may reduce the overall volume of your calls.
4. Use headphones or Bluetooth speakers: Connecting headphones or Bluetooth speakers with your iPhone can offer better control over the volume and provide a louder listening experience. Adjust the volume accordingly using the respective volume controls on the connected device.
5. Check for iOS updates: Make sure your iPhone is running the latest version of iOS (in this case, iOS 16) by going to "Settings" > "General" > "Software Update." Apple often includes improvements and bug fixes that may enhance the audio performance of your device.
6. Cleaning the speaker: If the speakers on your iPhone are clogged with dust or debris, they may not produce optimal volume levels. Gently clean the speaker grille using a soft, dry brush or a clean, lint-free cloth to remove any obstructions.
Please note that if you experience significant difficulties hearing sounds even at maximum volume, it might be worth considering a visit to an authorized Apple service provider or contacting Apple Support for further assistance.
