Hello Anonymous_User18,
Thanks for reaching out to Apple Support Communities. We see you have some questions about your AirPods being heard by those around you, and not sounding as loud as they should, and we'd like to help.
To verify do you have the AirPods Pro? If so, see if this is related to Active Noice Cancellation using the steps from the following link: AirPods Pro and AirPods Max Active Noise Cancellation and Transparency mode
If not, or the issue remains, we'd recommend trying to reset your AirPods, as this can sometimes help with sound issues: How to reset your AirPods and AirPods Pro
How to reset your AirPods and AirPods Pro
You might need to reset your AirPods if they won't charge, or to fix a different issue.
1) Put your AirPods in their charging case, and close the lid.
2) Wait 30 seconds.
3) Open the lid of your charging case, and put your AirPods in your ears.
4) Go to Settings > Bluetooth. Or go to Settings > [your AirPods].
•If your AirPods appear there as connected, tap the More Info button
next to your AirPods, tap Forget This Device, then tap again to confirm.
•If your AirPods don't appear there, continue to the next step.
5) Put your AirPods in their charging case, and keep the lid open.
6) Press and hold the setup button on the back of the case for about 15 seconds, until the status light on the front of the case flashes amber, then white.*

7) Reconnect your AirPods: With your AirPods in their charging case and the lid open, place your AirPods close to your iPhone or iPad. Follow the steps on your device's screen.
AirPods can be associated with one Apple ID. If you want to use AirPods (3rd generation) or AirPods Pro (1st or 2nd generation) that someone else has used, they first need to remove the AirPods from their Apple ID.
Regards.
