Sound checks were carried out a village school disco last night after a parent raised concerns about the possible damage to children's health.
Dr Paul Vickers, who teaches sound design at Northumbria University, became concerned about sound levels at the discos at Broomley First School, in Stocksfield, Northumberland, where his seven-year-old daughter Carys is a pupil.
He took his concerns to the Parent and Teacher Association (PTA) who agreed to carry out the sound checks to ensure no harm was being caused to children.
The father-of-three, of Main Road, Stocksfield said last night: "I have been to a few discos at the school and I have noticed that they are a bit loud and I wanted to find out just how loud they are."
He told The Journal that normal decibel levels in a night club are between 100 and 110 decibels, which people can tolerate for up to 15 minutes before their hearing is damaged.
"The school disco is an hour and a half long and I have worked out that a safe decibel level should be 94.
"I think this is something all schools should check. We're not trying to be killjoys we just want to protect our young children and we certainly don't want to try and stop the discos."
Chairman of the PTA Chris Pentney, who is also Folkworks programme manager at The Sage Gateshead, provided the sound check equipment and said: "We take the health and safety of our children very seriously and if there is anything we can be done to make the it a more pleasant environment for everyone then we will try it."
