Louis Tomlinson explained that Directioners are so loud, they've given him tinnitus.
The 1D singer said: "I am going slightly deaf in my right ear. It's tinnitus... something like that."
Despite Louis laughing off his deafness, One Direction management are taking it pretty seriously.
Apparently, the boys are being fitted with special earpieces to protect them from any further damage.

Yesterday, the One Direction boys were spotted at a recording studio in London. During their time there they were mobbed by fans, munched on chocolate and even ordered pizzas.
