Providing quiet areas where workers can gain relief from hazardous noise sources. For example, a soundproof or enclosed break room can keep noise significantly below hazardous levels. • Restricting worker presence to a suitable distance away from noisy equipment. This effective (yet simple and inexpensive) administrative control is applicable when workers are present but are not actually working with a noise source or equipment. In open space, for each doubling of the distance between the source of noise and the worker, the noise is decreased by 6 dBA.
Laboratory notebooks and invention record reports are also helpful for that defense. ” The former list describes the “novelty” requirements for an invention. Better yet, these considerations should be thought of as bars to obtaining a patent. Thus, if your invention was published in a printed publication, or on sale, or in public use before you file, you cannot obtain a patent. Under the old statute, inventors had one year to file after publishing, selling or using their invention publicly. The same grace periods appear to be available under the act.
In open space, for each doubling of the distance between the source of noise and the worker, the noise is decreased by 6 dBA. ENGINEERING CONTROLS Engineering controls involve modifying or replacing equipment or making related physical changes at the noise source (or along the transmission path) to reduce the noise level at the worker’s ear. In some instances, the application of a relatively simple engineering noise control solution reduces the noise to the point that no further noise protection is necessary.
