Specsavers is promoting its hearing centres with a new TV campaign showing an unlikely drum 'n' bass fan raising havoc by blasting out obnoxiously loud music from their car.

The 'Big Noise' ad, running now on national TV, shows a neighbourhood shaking to the sound of a thumping beat and rumbling bassline from a passing car.

Workmen are distracted from their drilling, a market stall collapses under the drone and a bus shelter shatters as the music reaches its crescendo.

But instead of a boy racer at the wheel, the oblivious hellraiser turns out to be a sweet old lady with hearing trouble who has no idea of the racket she is causing.

In typical Specsavers style the ad finishes with the line: “Need a hearing test? Should’ve gone to Specsavers Hearing Centres.”

The ad, as is the way for the company, was made in-house by Specsavers' own creative team. Creative director Graham Daldry said: “Hearing products are traditionally advertised in hushed, sweep-it-under-the-carpet tones.

"So it was nice to be given the opportunity to do things differently and break the mould. In fact, that reflects Specsavers’ approach to the hearing market as a whole very well.”

The song was recorded by a group of teenagers who feature in the ad. Director Sara Dunlop, from Rattling Stick, had cast the youngsters from a local college and when she asked what music should play they put forward their own tune.

The music technology students from Carshalton College now plan to release the track, which is called Get Mad Now.
