  • What is reverberation time and how it is calculated?

    What is the reverberation time of a room? Reverberation time is the time required for the sound to “fade away” or decay in a closed space. Sound in a room will repeatedly bounce off surfaces such as the floor, walls, ceiling, windows or tables. When these reflections mix, a phenomeon known as reverberation is created. Reverberation reduces when the reflections hit ...

  • In-House Oil Analysis Lab Saves Gold Mine Millions in Downtime, Repair and Replacement Costs

    A low-grade surface mining operation depends upon huge and expensive equipment such as Hitachi 5500 shovels and Caterpillar 793 haul trucks. Oil analysis is essential to identify problems so they can be corrected before they cause equipment to go down for major repairs. In the past, a multinational mining firm sent samples to an outside lab for analysis but the cost of this approach limited the ...

  • Why monitor dust in the workplace?

    Almost any place of employment can present a potential threat to health and safety from airborne particulates and aerosols. It is important to note, however, that dust hazards are not necessarily visible to the human eye and that the finest particles can represent the greatest threat because of their ability to travel deepest into the lungs. Effective monitoring is therefore key to the ...
