You must all travel with commoners. I've only once had a flight disrupted by a screaming kid and that was because the on-board staff refused to open any of the baby milk cartons that required scissors to open them (despite every parent on board having received the same assurance that such cartons could and would be opened).
Occasional screams etc - frankly, turbulence annoys me more. Can't someone sort that out? I'm looking at you, so-called scientists.
Probably more Sev's field but I hope this helps to reassure you:
Light turbulence - briefly causes slight, erratic changes in altitude and/or attitude.
Light chop - slight, rapid and somewhat rhythmic bumpiness without noticeable changes in altitude or attitude.
Moderate turbulence - similar to light turbulence, but greater intensity. Changes in altitude/attitude occur. Aircraft remains in control at all times. Variations in indicated air speed.
Moderate chop - similar to light chop, but greater intensity. Rapid bumps or jolts without obvious changes in altitude or attitude.
Severe turbulence - large, abrupt changes in altitude/attitude. Large variation in indicated airspeed. Aircraft may be temporarily out of control.
Extreme turbulence - aircraft is violently tossed about and is impossible to control. May cause structural damage.
