چکیده
The farm tractor fleet in the Brazilian market has increased. They are machines known to emit much noise. Noise can cause severe damage and disturbance people who work directly with around these machines. Therefore, aimed evaluate noise levels emitted by two cab tractors of different engine power, analyzing effect speed distance radius from source on occupational health. level outside inside cab, attenuation index, reduction provided sound insulation were determined. Attenuation indexes ratings satisfactory studying cab. most power better compared those lowest power. that operators exposed lower than limits established government laws. On other hand, greater not safe for workers' health if they at a less 7 m, requiring use an ear protector.

Outside and Inside Noise Exposure in Urban and Suburban Areas

By relating traffic flow to population density, a model of outdoor noise exposure has been developed for estimating the cumulative 24-hour noise exposure based upon the population density of the area. This noise model has been used to p...

We consider a model of liquidity demand arising from a possible maturity mismatch between asset revenues and consumption. This liquidity demand can be met with either cash reserves (inside liquidity) or via asset sales for cash (outside liquidity). The question we address is, what determines the mix of inside and outside liquidity in equilibrium? An important source of inefficiency in our model...
