About this sound

A public address opening sound with a chime and speaker tone, used to introduce announcements at schools, stations and events. Great for videos and intros.

This is the familiar opening sound of a public address system, the short tone and chime that plays just before an announcement begins. It starts with a soft electronic ding, followed by a brief pause and a warm, slightly echoing speaker tone that suggests a large hall, station or school corridor. The sound feels official and attention-grabbing without being harsh, instantly telling listeners to stop and listen. In a video it creates a sense of place and authority, making a scene feel like a real public announcement is about to happen.

Pro tip

Place it just before your announcement or reveal, with a short pause after the chime so listeners register the shift. Keep background music low underneath, and avoid using it twice in a row or it will lose its official, attention-grabbing effect.

How people use it

Opening a school assembly scene in a video.
Introducing an announcement at a train station.
Starting a funny office meeting parody clip.
Signalling a speaker before a stage presentation.

More information

Public address openings are a familiar part of everyday life in schools, stations, airports, offices and sports venues, where a short ding is used to gain attention before spoken information. Online, creators reuse that recognisable cue in videos, memes, sketches and presentations to signal that an announcement is coming, even when no real speaker follows. Because the sound is instantly understood across languages and settings, it works as a quick shorthand for authority, formality or a public event, and it remains popular for scene-setting and comic timing.
