The couple now face a charge of harassment for their late night heavy metal music habits, according to a report in the Aftonbladet daily.
"The harassment has just carried on, I am completely broken down. How can I keep living here," the neighbour said in police interviews.
The noisy dispute continued throughout the winter with the pensioners booming music from their terraced house in the Stockholm area until as late as 4am, the newspaper reported.
The police were moved to act and arrived at the house to find that the elderly couple had placed a music system on the balcony, pointed at the neighbour and playing Iron Maiden's "Afraid to shoot strangers" at top volume.
The police furthermore found another music system in the cellar directed towards the neighbour's bedroom wall.
The elderly couple are reported to have taken revenge on their neighbours, who had only recently moved in, due to a 'whistling sound' coming from their property.
The septuagenarian metal connoisseur argued in police interviews that she had been forced to take sleeping pills in order to overcome the noise.
"We wanted to give a taste of their own medicine," her husband said.
