Anti-noise headsets prices _ Houma anti-noise headsets _ Greek giant to create the perfect sound

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 significant local maximum, called formants. At these frequencies point, the reflected wave superposition, wave energy strengthened. Formant can identify phonemes, 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 cyclical anti-noise headsets manufacturers, namely the pitch appears a peak corresponding to the pitch is the pitch frequency at a certain frequency. And latent energy frequency born to focus on the low frequency spectrum only after the rapid decline over 4kH. For example, for the audio live transmission of anti-noise headsets sold by the recipient must be precisely the same sound as the original time series play, that the recipient of the incoming data must be accurately generated when their order of play, while selling anti-noise headsets, in order to accurately reproduce the input signal, the receiver must know the exact time of each packet generated when. Recipient of the data is converted back to analog form and put the pieces played by the analog signal accurately in accordance with the input time.
