Don’t play audio automatically

Automatically playing sounds doesn’t help your users. Your users don’t need audio distractions when visiting your website. You have a hard enough time getting them to do what you want. Some of your users will have problems focusing and unexpected sounds can distract them further.

What to do

  • Don’t have any audio that plays automatically.
  • Have all the audio you want, just let your users choose when they want to hear it.


Although you can pass this guideline by adding a pause, mute or stop function to automatic audio, that’s a bad idea. You don’t want your users frantically searching around your website for the audio control.
Users shouldn’t have to take action for a better experience, you need to provide it to them by default.

There’s a further exception on audio that plays for less than three seconds. Ignore this too. Three seconds of audio can still distract users, especially those who have problems maintaining focus.
