You seem to be getting a Safari popup - what their purpose is in playing a silly sound is beyond me

How to block pop-ups in Safari - Apple Support

On your iPhone, iPad, or iPod touch, go to Settings > Safari and turn on Block Pop-ups and Fraudulent Website Warning.

Great.

This happens when you visit "dubious" or "insecure" (ones that have been hacked) websites

Stay away.

The weak link in security is the human being using the device 😉
