Here, examples include tweaking an automobile door latching mechanism to impress a consumer with a satisfying click or modifying an exhaust manifold to change the tone of an engine's rumble. Aircraft designers are also using acoustic instrumentation to reduce the noise generated on takeoff and landing.
Noise control is a set of strategies to reduce noise pollution by reducing noise at its source, by inhibiting sound propagation using noise barriers or similar, or by the use of ear protection (earmuffs or earplugs). [20] Control at the source is the most cost-effective way of providing noise control.
An experiment free of the locality loophole is one where for each separate measurement and in each wing of the experiment, a new setting is chosen and the measurement completed before signals could communicate the settings from one wing of the experiment to the other.
A fanless CPU cooler based on heat pipe technology. A quiet, silent or fanless PC is a personal computer that makes very little or no noise.Common uses for quiet PCs include video editing, sound mixing and home theater PCs, but noise reduction techniques can also be used to greatly reduce the noise from servers.
Wood frame windows provide better insulation, but they are a poor choice for durability or maintenance (unless you choose wood-clad windows). Vinyl and fiberglass are better insulation and noise reduction materials. Certain windows have vinyl or fiberglass frames that feature chambers, to further enhance insulation and noise reduction. [7]
