Orthotics can help remedy this situation by: 1  Providing a stable base for movement. 2  Establishing an efficient gait. 3  Minimizing the effects of spasticity in limbs.  Creating an environment in which a child can take repeatable 1  steps. Reducing excessive energy used to move.  Aiding the transition between sitting and standing.
USG Research conducted the tests with a. variety of partition designs. The results: Thermaï¬ ber mineral wool. insulation in the 2.5 to 3.0 lbs/cu.ft. density range proved the best. overall acoustical performance. Densities above the 3 lbs/cu.ft. provided improved sound attenuation at high frequencies, but the. low-frequency performance starts to suffer at higher densities.
