Another child, who has had ear surgery, described how the device sets off her tinnitus (ringing in her
ears), and causes her significant pain. Two teenage girls described the noise as ‘going right through
you’, like “a sort of screeching noise.”5
The device frustrates parents too, who have reported that
children become agitated and need to leave public places, like supermarkets or car parks, quickly
and without explanation.
