Voice of long correlation. Also airflow pressure out of different intensity corresponds to the sound volume. From the perspective of the frequency domain, after voiced air flows through the channel, the amplitude-frequency characteristics at filtering of the channel will show two notable features. First, the amplitude frequency spectrum envelope has several distinct local maximum anti-noise headsets sales, called formants. At these frequencies point, the reflected waves are superimposed anti-noise headsets businesses, acoustic energy strengthened. Formant can identify phonemes selling anti-noise headsets, and a phoneme duration is relatively short when asked (syllable time), and therefore the spectral envelope reflecting the voice of the short-term correlation. Second, the fine structure of the spectrum is cyclical, that is the emergence of a peak spacing anti-noise headsets, the pitch is the pitch frequency intervals corresponding to a certain frequency. And latent energy frequency born to focus on the low frequency spectrum only after the rapid decline over 4kH. The gateway ARP table can have a buffer, phone-to-phone address resolution can be accomplished in the gateway. If not completed, by ARQ message to the gatekeeper address resolution request, the gatekeeper available ACF message will be sent the results of address resolution to the gateway, the gateway to the new address resolution data stored in the buffer. For card users, the gateway can be a one-time collection of user accounts, passwords, called number, etc., the use of ARQ-time access authentication and address resolution, can also be carried out twice. For pc users, requires a one-time pc will send user information, the called party number and other information with ARQ message to the gatekeeper. Supply of anti-noise headsets | Greek giant to build a bridge | Fenyang anti-noise headsets are provided by Shanghai Giant Network Technology Co., Ltd. Greek.
