Portable diesel generators, how to reduce the noise in

To reduce noise irritants, it has been suggested that the generator be placed somewhere outdoors. However, it may be too close to neighbors’ walls and is exposed to the weather. It would be far better to place a small portable generator in the garage or garden shed. But there will still be noise. Here are two more techniques to consider.

Identifying grinding mill dynamics using acoustic

The dynamic charge behaviour within mills is the key metric for operational diagnostics. As shown in Fig. 2, under relatively stable ore, ball, water and recycle feed rates, overthrow of the charge will cause extensive wear on mill liners; whereas, reduction in throughput is resulted when underthrow is exhibited.Studies have been conducted to develop on-line measurement solutions for charge

Resistor Types Does It Matter? Aiken Amps

2020-7-16  Shot noise. Shot noise is dependent upon current, so the more average DC current through a resistor, the more noise you get. In order to reduce this type of noise, you must keep the DC current to a minimum. This is best done in the first amplifier stage or in low-level stages such as reverb-recovery amps, where it is the most critical.
