"According to Jeff Peace, vice-president and program manager for 747, the "747-8... is 30 per cent quieter than the 747-400s in service with Qantas".Sad to say, a 30% reduction in noise equates to a 1.5 dB reduction, an amount that is barely detectible by the human ear.

Sad to say, a 30% reduction in noise equates to a 1.5 dB reduction, an amount that is barely detectible by the human ear. Please explain. The way it reads to me is that if the -400 was putting out 130 dB the -8 will put out <100 dB.
