Rule n° 120 - Sounds are user-triggered.

It is close to midnight, the children are sleeping, your surfing the Internet and, suddenly, a site triggers a thunderous sound. Maybe it's happened to you in the office. Lets not embarass our users and take away their control.

Goal

  • Give the user control over the visual and auditory interface when visiting a website.
  • Do not surprise the user by unexpectedly playing audio content.
  • Improve the accessibility of content for people with disabilities.

Implementation

Do not create audio content which starts automatically and without explicit user action.

Do not include in the page elements triggering the playback of an uncontrollable sound for example with the audio html element with the autoplay attribute or without the controls attribute.

Control

In each page containing audio content:

  • Check that there is no audio content automatically activated when the page loads;
  • Check that there is no audio content activated in an unpredictable way following a user action.

Overview and background

The 240 Opquast rules are defined and agreed upon by an extensive community of web professionals and academics. These web quality assurance guidance rules started as a list of best practices 20 years ago. They have since been revised every five years and have been tried and tested via millions of web interactions by Opquast community’s customers, including the leading CMS communities which have developed plugins for WordPress, Drupal and Prestashop. The most recent version, v4, was established in 2020.

Each rule has individual technical sheets and the rules can be searched by project phase or various topics: e-commerce, data-privacy, internationalization, security, code, etc, or by themes: accessibility, SEO, mobile, privacy, and ecodesign. The complete checklist is available on a creative commons license BY-SA.
