About headphone notifications and volume
Listening to audio on your headphones too loud for too long can damage your hearing. Headphone Notifications let you know if your audio exposure has been loud enough for long enough to affect your hearing—for example, over 80 decibels (dB) for 40 hours total within the last 7 days.
Your iPhone, iPod touch, or Apple Watch can now alert you when you’ve exceeded 100% of the 7-day exposure limit while wearing headphones.* These notifications give you more awareness of your listening habits to help you protect your hearing. When you receive a notification, you’ll hear a chime, and your volume will turn down automatically. You can dismiss the notification and turn your volume back up if you choose.
*The 7-day exposure limit applies only to media audio. Phone calls do not count towards your headphone audio exposure.
Check the Screen Time Restrictions, first, Settings > Screen Time > Content & Privacy Restrictions > Reduce Loud Sounds
