Inverts a channel’s phase. (To understand this key audio concept, see How sound waves interact.) Inverting all channels causes no perceived difference in sound. Inverting only one channel, however, can greatly change the sound.DeEsser effectThe...
Another studies showed that the shape of envelope and the frequency contribute to impression of warning sound. This paper describes the unclearpoints of previous, say, the effect of the envelope on detectability of warning sound. Investigations were carried out by using synthesized motor sounds which...

You may be tempted to think that the signal at 0Hz has no effect, but this is not the case. It still has an amplitude (of half the Modulator amplitude) and this manifests itself as an offset in the signal. We call this a DC (direct current) offset because, being at 0Hz, it ...
with the more intense frequency components shown in the third dimension or more simply as a darker point on a two-dimensional graph. The so-calledvoiceprintis an example of a sound spectrograph. At one time it was believed that people have voiceprints that are asuniqueas their fingerprints, ...
Acoustic holography method for measuring moving sound source with correction for Doppler effect in time-domain基于时域多普勒修正的运动声全息识别方法 The conventional acoustic holography method is not suitable for the measurement of the moving sound source, because the Doppler effect exists in the sound ...
Therefore, the boundary layer effect can be ignored in the manipulation of reflection amplitude and phase13,14. Such a significant feature of independent control of reflection amplitude and phase enables a complete manipulation of sound in 3D space. High-fidelity acoustic hologram First, we show ...
Numerical simulations based on the nonlinear parabolic wave equation are used to investigate time reversal of sound beams radiated by unfocused and focused sources. Emphasis is placed on nonlinear propagation distortion in the time-reversed beam, and specifically its effect on field reconstruction. Distor...
The use of a sound wave created by an external source and directed along the positive column of a nitrogen discharge in order to make the discharge pass to the contracted state is studied experimentally. A phenomenon involving a jump in the sound wave amplitude, caused by the discharge contract...
