If you live or work in lcoations with a ton of extraneous mouse (the author look meaningfully out the window at the rumbling carpet cleaning van 15 yards away), noise-cancelling headphones can be a godsend if you need to be able to hear details in audio or music, rather than just recognize bits and pieces as they go by. To that end, high-end audio company Bose has announced its QuietComfort 15 Acoustic Noise Cancelling Headphones, which… Read More

Of all the new technologies LG highlighted at its press conference on Thursday, the demo that got perhaps the biggest reaction came from relatively mundane noise cancellation tech. The laughs of disbelief may not quite have been quite the reaction the company hoped for, though. LG’s new DSE noise reduction uses dual microphones within a phone to digitally filter out background noise. The company’s Chief Technology Officer, Dr. Woo Paik, showed… Read More

Many people who have succumbed to the temptation of noise canceling headphones can give an opinion about how effective the noise-reduction technologies can be: suffice to say some are more effective than others. But one thing the majority of users seem to agree on: as far as audio quality goes, noise-canceling headphones usually aren't anything special, and sometimes they're downright terrible. JVC aims to change that with its… Read More

Audio and electronics manufacturer JVC has announced its new HA-NC80 noise cancelling headphones. The NC80s featur dual-mode noise cancellation circuitry which enables users to adapt the noise-cancellation feature to different environments: a “wide” setting cancels frequencies across a broad range (like, say, noise on a commercial airliner), while a “low” mode cancels a narrower set of frequencies (like, say, typical… Read More

Electronics maker JVC showed off a bundle of products at CEDIA this week, including a pair of new 40- and 46-inch LCD televisions which support native 1080p resolutions and offer optional RS-232C control interfaces for integration with home or business automation systems. The 40-inch LT-40FN97 and LT-40FH97 and the 46-inch LT-46FN97 and LT-46FH97 (the model numbers with the “H” denote the RS-232 interface) each offer full 1,920 by… Read More

Noise-canceling technology uses a built-in microphone that detects environmental noise from low-frequency sources (20-1500hz), such as jet engines, leaf blowers, subway trains, server fans, and household appliances. Sony engineers have improved a noise canceling circuit that creates an equal an opposite sound wave to cancel such noise, creating a better environment for listening to in-flight movies or portable audio devices. For example,… Read More

A recent study compared the performance of Shure sound isolating earphones against three models of noise-canceling headphones and found that the sound isolating design was more effective at reducing the level of a broadband noise signal. The tests were conducted in accordance with recognized industry standards for measuring the noise attenuation capabilities of hearing protection devices and noise-canceling headphones. The study results… Read More

Designed for on-the-go music or multimedia lovers who demand the best in quality, the AHP712 measures ambient noise across an unusually wide range of frequencies, then creates counteractive soundwaves that reduce outside distractions to deliver the best audio experience possible. “Altec Lansing's new AHP712 is ideal for frequent travelers who love movies, music or games, but who often deal with outside distractions like jet engines… Read More

“Sometimes noise is a good way to identify mechanical faults — where noise isn't a problem but can lead you to problems,” SenSound president Sergio Mazza said. “We analyze over several frequencies, to tell the manufacturer where and at which frequency noise is leaking.” Read the full story at CNN.com.

Quote from the review at HiTechMods: “Zalman is mainly known for silent cooling products in their Computer Noise Prevention System line. The newest product to come from Zalman has nothing to do with lowering noise levels but rather creating noise. They have changed focus away from cooling products to create a new set of 5.1 channel headphones. During the night or at LAN parties loud speakers are not very practical because you… Read More
