What are the potential drawbacks of using sound files instead of images in PHP scripts for user notifications?

Using sound files for user notifications in PHP scripts can have drawbacks such as increased load time, potential compatibility issues across different devices and browsers, and the possibility of annoying or disruptive sound notifications for users. To mitigate these drawbacks, it's recommended to use visual notifications, such as alert messages or pop-ups, instead of sound files.

// Example of using a visual notification instead of a sound file
echo '<script>alert("Notification message here");</script>';
