Oof sound effect

Forced out on a hard exhale, falling in pitch and stopping dead. The default reading, and the only one that reads as real damage rather than commentary on it.

Flat, level and completely unbothered. Taking the effort out of the delivery turns an injury into a punchline, which is a different beat entirely.

Held long and falling slowly, as somebody watching rather than somebody hit. It puts the speaker outside the moment, which is what a reaction video usually wants.

Down in the chest, gruff and clipped short. The lower register reads as weight landing on somebody, so it suits a fall or a heavy tackle on screen.

No word in it at all, just the air leaving on a rough voiced huff. Use it when a character is visibly on camera and a clean spoken syllable would look dubbed.

Several people reacting at once, arriving slightly apart rather than together. The uneven timing is what makes it read as a room and not a stacked take.
