Prank Sounds
A prank soundboard built from the sounds people react to before they think: fake notification tones, doorbells and knocks, and the disconnect noises that start someone troubleshooting. Play any prank sound instantly, download free MP3s, or add one to your own board.

A prank soundboard works on reflexes rather than jokes. The best clips here don't make anyone laugh at the moment they play. They make someone look up, check a phone or mute themselves, and the laugh arrives afterwards when they work out why.
Sounds That Get a Reaction
Three things reliably work. Alert tones, because everyone is trained to respond to them. Ambient noises that shouldn't be there, like a doorbell or a knock, because the brain insists on locating them. And sounds implying a technical fault, like a disconnect or a dropped call, because the target starts troubleshooting instead of listening. Nearly everything effective in this category falls into one of those three.
Selling It
Volume is what gives it away, every time. A clip played louder than the real thing would be reads as a soundboard instantly and the whole effect collapses. The convincing version is quieter than you think it needs to be, ideally just under the ambient level of the call, so the target leans in rather than reacts. Timing matters less than level here, which is the opposite of most audio on this site.
The other giveaway is repetition. A real notification arrives once.
Boards Worth Raiding
Most of the genuinely effective material lives elsewhere. The notification soundboard is the single richest source, since alert tones do most of the work in this category. The airhorn sound family is the opposite approach and fools nobody, though it has its uses when subtlety isn't the point.
Where the Line Is
Worth saying plainly: this stops being funny the moment the target can't opt out. A notification sound in a group call is a prank. The same sound played repeatedly at someone working, or at someone who has asked you to stop, is just noise directed at a person. Anything aimed at pets sits in the same bracket, since an animal has no way to understand it as a joke.
The rest of this button soundboard is built for people who know a sound is coming.
Frequently Asked Questions
What is the most convincing prank sound?
A notification or alert tone, because the response to one is trained rather than considered. Anything implying a technical fault works nearly as well, since the target starts troubleshooting instead of listening for the source.
Why do prank sounds stop working?
Almost always volume. A clip played louder than the real thing would be identifies itself as a soundboard immediately. Repetition is the other giveaway, because a genuine notification arrives once rather than three times in a row.
Are soundboard pranks a problem in voice calls?
Only when the target cannot opt out. In a group call where everyone knows the format it is part of the conversation. Directed repeatedly at one person, particularly after they have asked you to stop, it stops being a joke.
