Example of admissible sound<br />
pressure level at place of immission<br />
To improve the quality <strong>and</strong> to increase the capacity,<br />
the coal logistics belonging to the coking plant got<br />
<strong>new</strong>ly planned <strong>and</strong> organized. The stockyard <strong>for</strong> coal,<br />
served by wheel loaders till now, has been equipped<br />
with automatically-operated machines <strong>and</strong> belt conveyor<br />
systems.<br />

TRANSFER OF TECHNOLOGY<br />
For being capable of detecting <strong>and</strong> analyzing the<br />
admissible acoustic emission levels, 6 test points have<br />
been fixed round the steel works, at the nearest residential<br />
areas. Because of the admissible sound immission levels<br />
to be kept according to „TA Lärm“ <strong>and</strong> the administration<br />
rules being part of it, maximally admissible sound pressure<br />
levels have been defined <strong>for</strong> these measuring points.<br />
