Resistor Types Does It Matter?

Depending on the tube type and input stage topology, the resistor noise may be greater than the tube's referred input noise. To reduce the noise to a minimum, use the smallest possible input grid resistor value that still provides RF suppression. Also, since resistor noise is proportional to current flow, a 100K grid resistor is going to be

How do wind turbines work Ecotricity

While wind turbines have been problematic due to noise in the past, most modern windmills make very little noise and are unlikely to cause disruption. Wind turbines are usually placed a minimum distance of 300 meters away from residential homes, with sound levels reaching just 43 decibels. That's about the same noise level as a fridge.
