Sound playing on web sites can be annoying, and often there is no option to disable the sound on the site. There are a number of ways to disable/block sound produced from websites. Embedded audio is easier to block than Flash audio. Solutions differ for different operating systems, and different web browsers.

Internet Explorer[]

Go to Internet Explorer options and uncheck the option "Play Sounds in webpages"

(but sounds from Flash objects will play anyway)


Flashblock (flash audio only)
  • This is the best solution for blocking undesired Flash audio. It replaces all flash objects with a play button. Only after the button is pressed will the Flash object start.
Adblock (flash audio only)
  • Another solution in to install Adblock, a firefox extention
    • This option will enable you to block a flash obect is it offends your ears. Each flash object will have to be blocked individually and will be block from then on.

  • This will disable embedded audio for all websites
  • Editing the userContent.css file locate in your users directory
    • Linux: ~/.mozilla/firefox/xxxxxx.default/chrome/userContent.css
