Concrete Construction: Can Sound Travel Through Concrete

Concrete Construction: Can Sound Travel Through Concrete

Feb 25, 2019 When absorption occurs, the sound wave is converted into heat energy. So, how does sound travel through concrete Concrete walls are designed to reflect noise towards the source and absorb some of the energy from the sound wave. Most of the sound energy isn’t traveling through the wall, which is why it provides such an effective noise barrier.

In general, the STL of a concrete masonry wall increases with increasing frequency of the sound. Many sound transmission loss tests have been performed on various concrete masonry walls. These tests have indicated a direct relationship between wall weight and the resulting STC—heavier concrete masonry walls have higher STC ratings.

Cement reacts well to a vibrator frequency of 3600 vibrations per minute or higher. The high frequency vibration helps to aerate the cement and make it flow freely. Rotary vibrators churn the cement and are better to use than piston and electro-magnetic vibrators that have a ten-dency to pack the cement. 1.

What Industrial Crushers Are. Crushing equipment reduces large materials into a smaller size. A typical impact crusher or other type of rock crusher uses a great deal of force to reduce the size of rocks. They operate on mechanical force for breaking apart the large rocks as opposed to chemical or laser methods of breaking rocks. In many cases, primary crushers are a part of a large materials.
