The QuietPower output-ripple-attenuation module, dubbed QPO-1, relies on active filtering in a SIP package. It can thereby provide more than 20 dB of conducted differential noise attenuation from 60 ...

Compatible with most switchmode dc supplies from 3 to 30 Vdc, the QPO-1 output ripple attenuation module provides active filtering in a 25 mm x 25 mm x 5 mm SIP. It provides greater than 20 dB of ...

3D printing techniques enable quieter, higher performing designs for final control elements. Control valve noise is a problem in many plant environments. The sound is created by very high pressure ...

Often at noisy facilities, there is one process or area that generates extremely loud noise. It typically is task-specific (such as tank cleaning, motor run-up tests or demolition projects) or ...

One difficulty with hearing protective devices (HPDs) is selecting the right one. Careful forethought is required to select HPDs that will help ensure that workers obtain maximum effective protection.
