Understanding what the rules are is only half of the battle with noise. The other half is assessing noise levels and utilizing effective controls. Occupational noise exposure and hearing conservation ...

According to the Occupational Safety and Health Administration, 22 million people—including nearly all power plant workers—are exposed to potentially damaging noise at work each year in the U.S.

Figure 1 depicts the nature of the information provided by measuring a signal in the time domain vs. the frequency domain. Both provide insight into the content of the signal and possible approaches ...

Engineers are not just adding more insulation, they are reinventing how interior noise is captured, modeled, and judged so ...

In order to control noise, designers must first determine where the noise source or sources are how much each is contributing to the overall level, and their frequency signatures. In order to control ...

Phase noise is a critical parameter in most phase-locked loop (PLL) synthesizer applications. In radars, for example, phase noise at low-offset frequencies translates to the ability to discern between ...

Noise-induced hearing loss is a prevalent workplace injury in the modern industrial plant. Employers must manage workplace noise exposure. Doing so is complex in terms of accurately assessing sound ...

Sounds that are lower pitched are less studied than other types. Some say it’s a health hazard. Others have doubts. By Lourdes Medrano/Undark Published Apr 17, 2024 8:00 AM EDT This article was ...

Brown noise has a low, natural sound, so many people find it easier on the ear than white noise. Examples of brown noise include rushing waterfalls or rivers, heavy rainfall, and rumbling thunder.

A white-noise source can be constructed based on the random noise of a Zener diode or reverse-biased base-emitter junction. While these circuits work, they are temperature sensitive and not ...

Noise isolation in over-the-ear headphones depends on fit materials, cup design, and sealing rather than technology alone ...

Having trouble falling and staying asleep is a common problem many people have. The American Academy of Sleep Medicine with the Sleep Research Society found that over one-quarter of American adults ...
