A study carried out by Spanish researchers has shown that the presence of chemical contaminants can interact with noise and modify, for good or for bad, the way in which work-related "deafness" "“ which is increasingly common among young people "“ manifests itself. Noise-related hearing loss is the most common occupational disease in Europe. "Workers exposed to noise in the presence of metalworking fluids exhibit a delay in hearing alteration in comparison with those exposed only...

The widespread use of true random number generators (TRNGs) has taken a step closer following the creation of the most lightweight designs to date by researchers at Queen's University Belfast's Institute of Electronics, Communications and Information Technology (ECIT). Members of the Institute's cryptography research team have produced a series of circuits that are up to 50 per cent smaller than anything else currently available. Optimised for digital circuits, FPGA and ASIC, they push...

ROCHESTER, N.Y., July 14 /PRNewswire/ -- Revolutionary new ZEM headphones use just a simple amplifier to produce pure sound in the earpieces, unchanged by electronics. They simultaneously cancel background noise using patented technology invented at Syracuse University by renowned acoustic researcher Dr. Jozef Zwislocki. The result is pure, unaltered sound that feels as if you're in the recording studio. The absence of complex electronics also lowers cost and produces a headset weight of...
