Doorbell sound effects

A warm ding then a lower dong. The most recognisable doorbell there is, and it reads as an ordinary suburban house.

A flat rasping electric buzz. Older and cheaper than a chime, and it makes a building feel institutional rather than homely.

Four descending bell-like notes with a long ring. It reads as a larger, older, more formal house.

Two clean synthetic notes with a digital decay. It dates a scene to the last few years more precisely than any prop.

The same chime hit four times impatiently. The repetition carries the whole character of whoever is outside.

Rounded and slightly distant, with a room around it. It places the listener inside, which is where the scene usually is.
