There are really three factors here: dishonesty, dramatics, and the overall noise level.
Round tables are more expensive, but they allow students to talk, not shout, reducing overall noise in a school.
With that sort of increase, it's going to be pretty hard to argue that overall noise levels won't increase.
Mostly, the effect on overall noise is less than 3 dB.
Because of the low loss of these coatings, the overall noise of the test cavity is dominated by contributions of the Zerodur spacer and silica substrates.
All Infinium HD BeadChip markers have an average 15-18 fold redundancy, yielding low overall noise (average std dev log R ratios < 0.2) for copy number measurements.
Whine noise of main gearboxes is an important contributor to overall noise and acoustic discomfort in helicopters cabins.
Thus, reducing airframe noise makes a great contribution to the overall noise reduction of a civil aircraft.
Although rail transport has a low environmental impact overall, noise from goods trains remains a major problem.
The sound pressure level shows that while some surface imperfections are not affecting the overall noise, certain types of such imperfections can increase slightly the overall noise level at low rotational speeds, or can decrease slightly the overall noise level at high rotational speeds.
Noise levels generally vary with time, so noise measurement data are reported as time-averaged values to express overall noise levels.
