propriately wallpapered walls, curtains, and other sound-reducing features.
Loud working equipment, such as matrix printers, should be installed in
sound-absorbing cases. The permissible noise levels for office equipment
are determined in the DIN standards.

An air conditioner should not increase the normal noise level.
Strain caused by excessive noise can also be reduced by an organizational
restructuring of work.

Buying a Screen
If you already have poor sharpness of vision, low-quality screens can make
things even worse. Apart from eye problems, tenseness, fatigue, and many other
disorders can be caused.
things even worse. Apart from eye problems, tenseness, fatigue, and many other
disorders can be caused.
The latest technological developments are triniton, or black-matrix, screens and
TFT flat screens. Unfortunately, flat screens are still relatively expensive. There
are extensive standards that regulate the readability of the depicted information.
When buying a screen, it is recommended to study the extensive standards to
avoid a wrong purchase. One thing is certain: a good screen is usually expensive.
The normal tube screens do not last forever. They only retain their focus and con-
trast for a few years.

All depicted characters should be sharply defined and clearly legible up to
the edges of the screen. A positive representation (dark characters on a light
background, as in a book) is recommended.

As the depicted characters must be large enough, a 17-inch monitor is rec-
ommended, at least for graphical user interfaces (like KDE). For the pro-
cessing of CAD, layout, and graphics, it should be 21 inches.

It is especially important that the screen does not flicker. In concrete terms,
the minimum sync frequency with 15-inch monitors should be at least 73
Hz. However, 85 Hz is recommended. For larger screens, such as 21-inch,
100 Hz is a good value.
