Plantronics office headset on its charger. In the 1980s, Plantronics created a line of cordless products using infrared technology. Though the technology utilized was the same one being used by television remote controls, the link did not require a Federal Communications Commission (FCC) telecommunications approval. One of the first products ...
After successful sales for the DSP-500 and the Xbox Communicator headsets, [3] In 2004, Plantronics announced the GameCom brand with four new headsets for Xbox Live and Online PC gamers: GameCom X10 and X20 for Xbox Communicator, and GameCom 1 (analog) and GameCom Pro 1 with digital signal processing built-in sound card and connected to a PC via USB port.
Radio noise near in frequency to a received radio signal (in the receiver's passband) interferes (RFI) with the operation of the receiver's circuitry.The level of noise determines the maximum sensitivity and reception range of a radio receiver; if no noise were picked up with radio signals, even weak transmissions could be received at virtually any distance by making a radio receiver that had ...
At this time, Koss pioneered the high-end "electro-static" "ES series" headphone market. These headphones set the standard for wide-range frequency response. Being very durable, they required service for wear and tear on cords and earpads during their lifespan, by K&M Electronics (Klenworth & Midwest based in Minneapolis), working out of the TV ...
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.
A LectroFan white noise machine A clock radio that includes a white noise machine. A white noise machine is a device that produces a noise that calms the listener [citation needed], which in many cases sounds like a rushing waterfall or wind blowing through trees, and other serene or nature-like sounds.
A headset is a headphone combined with a microphone. Headsets provide the equivalent functionality of a telephone handset with hands-free operation. Among applications for headsets, besides telephone use, are aviation, theatre or television studio intercom systems, and console or PC gaming.
