I turned off all notifications and it's still happening. I can't really describe it. It's like a drop of water from a faucet - that's the nearest I can describe it. It's annoying. It happens whether I'm on the Mac or not, screen awake or sleep. Please help!
iMac 27″, macOS 15.1
Thank you, den.thed. I found the issue - it was Skype notifications, even though I had turned its notifications off. I finally had to quit the application. I'll keep your suggestion in mind for the future!
Go to Apple > System Settings > Sound and test with "Play user interface sound effects" switch turned Off.
Good work, I'm glad to hear that you sorted it out.
My Mac is making an alert sounds and I can't find where it's coming from
