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.
