The Sound Damper is a device that generates a faint electromagnetic field which slows the vibrations of air molecules within it. The field can be of many sizes, and can be either a solid sphere or a spherical shell. By damping the air vibrations, it slows or stops the transmission of sounds through the field, and also, as a side effect, makes the interior of the field quite cold. | The Sound Damper is a device that generates a faint electromagnetic field which slows the vibrations of air molecules within it.

The Sound Damper is a device that generates a faint electromagnetic field which slows the vibrations of air molecules within it. The field can be of many sizes, and can be either a solid sphere or a spherical shell. By damping the air vibrations, it slows or stops the transmission of sounds through the field, and also, as a side effect, makes the interior of the field quite cold.
Sound Dampers have a number of uses: for instance, they are used to make conversations private, to silence loud machinery, and to allow spies and assassins to move quietly. They also make up an integral part of a vehicle stealth systems.
Sound Dampers come in many sizes, from 500g to several tonnes. They cost approximately Cr2000 per kg, and have a maximum field diameter of 2 metres per kg. Each metre eliminates about 15 decibels of sound. TL 15.
To hear a sound which has passed through a Damper:
