A student at the University of Dundee has developed a solution to noise pollution - a "NoiseBomb" which can be dropped on offenders.
Jennifer Kelloe's invention records excessive noise
Jennifer Kelloe's small device can record excessive noise and be posted back through offenders' letterboxes.
She has also developed stand alone "Do Not Disturb" signs which "shout" at passers-by to give them an indication of annoying anti-social noise.
The 22-year-old's exhibition is part of the university's degree show.
Miss Kelloe, a student at the Duncan of Jordanstone College of Art & Design, said her nuisance noise awareness campaign had already proved to be effective.
She said: "The NoiseBomb is a way of telling your neighbours just how disruptive their noise has been without having to get in a direct confrontation with them.
"The signs I've developed are more of a general awareness thing to show just how annoying unwanted noise can be.
"I posted a prototype of the signs in the art college and it wasn't long before people were complaining that they were really annoying so I took that as a sign that it works."
Miss Kelloe added that the idea for the NoiseBomb and signs came after attending student parties where the noise had become a problem.
"Anti-social behaviour is obviously something that has been in the media a lot and I was aware from speaking to various people that noise is the biggest nuisance to a lot of people," she said.
"I thought I would develop a noise awareness package that is very different from traditional approaches to trying to get people to just turn it down."
