Eating crunchy food was enough to give Julie Redfern (not shown) a migraine.

 A British mom claims to have supersonic hearing — saying she can hear her brain wobble, eyeballs move and heartbeats.

Julie Redfern, 47, suffers from a rare inner ear condition which means any internal noises are amplified to deafening heights in her own head.

It has forced the mother of three to give up eating crunchy foods — like apples and crisps — after they subjected her to migraine-inducing thuds.

She also regularly loses her balance — and admits to sometimes feeling “drunk without having a drink.”

“It’s very frustrating being able to hear everything. Maybe I wouldn’t [mind] if it was just a bit of gossip but nobody wants to be able to hear their body constantly,” she said.

Redern — a receptionist from Padiham in Lancs — first spotted the signs of her condition when playing video game Tetris at home in 2006.

Following the bricks from side-to-side, she heard a weird squeaking sound — which she soon realized was the movement of her own eyes.

Doctors were left stumped, but she soon stumbled across the story of a man who had suffered from similar symptoms.

Self-diagnosing herself as having superior canal dehiscence syndrome — the thinning of the temporal bone so it exposes the inner ear to more sound — she was admitted to hospital.

Doctors soon officially diagnosed her with the condition, speculating that a serious bike crash in 1991 may be to blame.

She underwent five hours of surgery to correct the damage on her right ear — and hopes to have the left ear operated on by the end of the year, reports the Telegraph.

“I couldn’t have coped with it for another 40 years, seven was enough,” said Redfern.

“I know when I have the other ear done, I’ll be cured — but you never know I might miss not hearing all these strange little things.”
