If you've ever seen a Jewish man with strings hanging out of his clothing, this is probably what you were seeing. There is no particular religious significance to the tallit (shawl) itself, other than the fact that it holds the tzitzit (fringes) on its corners.
Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average, or equilibrium) atmospheric pressure, caused by a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unit of sound pressure is the pascal (Pa).
Sensitive hearing can develop from hyperacusis, phonophobia, or recruitment. Hyperacusis, or hypersensitivity of hearing, is a rare hearing disorder in which tolerance to ordinary or everyday levels of sound or noises is lowered, so that they are heard as unusually and uncomfortably loud and intense.
