Industrial amenities include a wide range of applications such as construction sites, processing plants, manufacturing and more. The general sound issue in most of the industrial applications is the requirement to reduce the overall sound level or reduce the decibel level of particular machinery.

Machinery may include pumps, jack hammers, drills, air tools, grinders, crushers, printing equipment, punch presses etc. The noise generated by these machines not only fatigue operators but might not meet OSHA safety needs or other local ordinances.
To reduce the sound level of these machines, the best course of action is to create a soundproof enclosure across the noise source. This will eradicate noise and prevent sound from premeating into the rest of the amenity or neighboring areas. There are several ways to achieve this; nonetheless, most techniques will need some type of dense or massive material and possibly the addition of a fluffy absorptive material.
To create sound proof enclosures, you might want to consider using a blend of the following materials:
Gymnasium and indoor sport halls vary considerably ...
... from other secondary rooms in that they are quite bigger spaces meant in general for teaching groups of active students. Thus, they have a strikingly different acoustic ambience. Sports halls are rated as the hardest learning space to hear in. Though design criteria for the acoustics of gymnasium and indoor sports halls are part of current building regulations, in reality it has been hard for designers to accomplish these standards. Sports amenities like gymnasiums and sports halls are big open spaces made to endure years of use for an assortment of sports. They are made with floor, hard wall and ceiling surfaces making them specifically poor acoustically. These spaces are frequently used for different kinds of activities making their acoustic performance vital to alleviate clear communication and offer an enjoyable ambience whether the activity is a school assembly or one of the different sports that are performed in these settings.
Sports hall acoustics are generally boomy due to a blend of big areas of corrugated steel ceilings, hard block walls, and wooden floors along with high ceilings. To control sports hall acoustics, a big amount of acoustically absorptive material need to be applied across the hall. A spray-on material has a unique advantage over acoustic panels in this situation.
When the sound reflections blend, a phenomenon called echo is created. Echo lessens when the reflection hit surfaces that can absorb sound like chairs, curtains and also people.
Sound absorption and reflection
Once emitted from a source, sound waves in hall travel through the air until they reach a boundary surface or other barrier. When a sound wave hits a surface, it will be partly reflected off the surface back into the hall and keep on travelling in a new direction, and it will be partly absorbed by the surfaces with the absorbed energy dissipated as heat.
