Calculating Noise Reduction Coefficients Decibel Drop

To determine the coefficient (C) of sound reduction, use the decibel drop (d) in the following formula: Example: for a 23.1 dB drop, the coefficient is 0.93: Therefore, the coefficient for this material combination at 1 kHz is 0.93. This test will need to be repeated for different frequencies. Get price

Hot Mix Asphalt

Overview Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together. Our HMA is mixed at our asphalt production Get price

3. CALCULATION OF MACHINE RATES

3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for $60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.

Management Measures: How to calculate your maintenance

Jun 14, 2013The KPI "Weeks of Maintenance Backlog" reflects the amount of work that is lined up to be planned, scheduled, and performed by the maintenance department. Derivation: As usual, the concept is simple — how much work does the department have piled up? But the data still have to be developed and standardized. To minimize random noise in the KPI, some guidelines need to be in place. Get price

A procedure for rapid determination of the Bond work index

The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (W i). This index is determined on a laboratory-scale using a Bond ball-mill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained. Get price

Process costing

May 14, 2017Process Costing Overview. Process costing is used when there is mass production of similar products, where the costs associated with individual units of output cannot be differentiated from each other. In other words, the cost of each product produced is assumed to be the same as the cost of every other product. Get price
