• The Center for Operator Performance (COP) announced May 1 that new research it sponsored shows that some standard alarm tones in distributed control systems (DCS) may be undetectable by older operators with age-induced hearing loss, especially in the presence of control room noise. A pilot study by John Casali and Kichol Lee of Virginia Tech University conducted spectral analyses of alarm sounds in two refinery control rooms. They found that some common DCS alarm sounds such as chimes are mostly in the same frequency range affected by age-induced hearing loss, which means older operators may not be able to hear alarms using these sounds. A more detailed study to determine optimal alarm sounds and make recommendations is being planned. 

Yokogawa Corp. of America and Dover Energy Automation announced May 1 they're joining forces to create the Well Managed product portfolio that will give users an optimized business operations solution.
