odd thing is that I've just bought a quaint electronic device that drones out white noise (or, if I let it, the crash of the surf breaking on the shore) to cover the sound of the local drummer, barking dogs and screaming kids in nearby gardens. What it does, now I come to think of it, is create a hum and if it's loud enough it almost drowns out the other sounds.  I'd advise those attending the trial to give it up and learn to love your hum -- there might be much worse noises out there if you stop hearing it. I too hear the hum and welcome it, particularly since seeing and believing the scene in the movie 'Children of Men' where Clive Owen's character is told: "You know that ringing in your ears? That's the sound of the ear cells dying, like their swan song. Once it's gone you'll never hear that frequency again. Enjoy it while it lasts." As a friend of a long-time sufferer of 'head hum', I can only suggest more tact and consideration be applied to this subject. Both 'head hum' and tinnitus can cause great discomfort and frustration. Poor Katie Jacques. After a career in which naughty children were dealt with, where nuisances were fished out, quarantined and expelled, she now has to endure something she can't even reach with a cotton wool bud. Attempting to 'learn to love your hum' would be like trying to love Gok Wan. Naturally irritating, overwhelming
