Like every regular concertgoer, he's a bit fed up with the various sonic disturbances that punctuate the typical night out. So, combining his professional and recreational interests, he's created a 'Cough Culture' website, which includes an etiquette guide to coughing in concerts.
He stresses it's not a rule book. "Anyone who coughs has a reason," he says - a cough is an involuntary reflex that can't be easily suppressed or controlled. Instead he is setting out to help the afflicted manage their coughs "with understanding and humour".
He splits his tips into three parts - location, timing and volume.
1 - Where? If you're really sick, says Professor Lamprecht, give up your ticket, stay home, and don't spread your germs. If you must go, and you know there's a good chance you'll cough, try moving to a seat where you'll disturb fewer people. Ask someone at the very back if they'd like to swap for your seat further forward (I suspect this one works better in Essen than the Royal Festival Hall). If you get caught out by a surprise coughing fit, either try to change places or just leave.
2 - When? If you can't suppress a cough until the end of the show, then at least wait for a round of applause . The next best choice is during a very loud passage - discreetly. It's essential to avoid coughing between two sections of a work. "If there's no applause, it's not a break!" Professor Lamprecht reminds us - something you'd never guess in London, where entire audiences hack away between movements with impunity, whether they're ill or not. The other time to avoid coughing is during very quiet passages.
3 - How loud? If you really must cough, the quieter the better. A big handkerchief held in front of the mouth helps to dampen the sound. If you don't have one, cough into your elbow. It muffles the volume and has the added advantage that you won't pass on germs when shaking hands.
Finally, he has a tip for the coughers' victims. Don't hiss and don't protest loudly, he says - it only creates more of a disturbance.
