I’m sure I’m not the first person to warn you about the dangers of loud noises. Our ears are remarkably sensitive organs and they can suffer permanent damage after a surprisingly short exposure to sounds in excess of 100 decibels (dB). It’s why people who routinely work with heavy machinery wear hearing protection. But for everyone else who simply goes about their lives doing normal things like listening to music, the threat of hearing damage seems like a faraway risk, not something that needs to be guarded against. And that’s exactly wrong. Noise-induced hearing loss (NIHL) is a slow-moving epidemic. The National Institute on Deafness and Other Communication Disorders (NIDCD) estimates that more than 40 million (about 12%) of American adults ages 20-69 have some kind of hearing loss . Half of these people don’t experience any loud sounds at work. What makes NIHL so insidious is that it’s almost impossible to detect in its early stages. Because it’s cumulative, repeated loud … [Read more...] about A deafening epidemic: The rise of noise-induced hearing loss, and how to stop it

Laptops and desktops running Nvidia’s GeForce RTX 3000 graphics just got a new feature this year called resizable BAR (base address registers). The feature arrived with the debut of the GeForce RTX 3060 , and through software drivers coming in March, it will work across Nvidia’s line of 3000 series GPUs on desktop and mobile . For GeForce gamers, the added support for resizable BAR means you’ll get a performance boost in select games without having to upgrade to a more expensive GPU , which is definitely good news. What is resizable BAR? Resizable BAR is a feature of the PCI Express interface that Nvidia chose to implement on its latest graphics cards, and it allows the processor and the graphics card to share access to resources for faster data transfer. In fact, Nvidia’s implementation isn’t unlike what rival AMD previously demonstrated with its Smart Access Memory, which allows its Ryzen processors to better and more efficiently communicate with its Radeon GPUs. … [Read more...] about Nvidia’s resizable BAR explained: What is it and how can you get a gaming boost?
