When the sound vibration is (6)s low, we call this a low-pitch (音调) sound. But when the sound vibration is fast, we call this a high-pitch sound. Pitch (7)d escribeshow high or low a sound is. When the sound has less energy, we say it has a soft volume...

loud. Others are quiet. The loudness of sound is called volume. A human baby's crying is louder than the flying of a bee. The more air that vibrates (振动), the louder the volume is. Sound also can be high or low. This is called pitch. Pitch depends on how fast ...
Such fingerprint exhibits strong robustness, due to its statistically stable nature, against various audio signal distortions such as recompression, noise contamination, echo adding, equalization, band-pass filtering, pitch shifting, and slight time scale modification. Experimental results show that in a ...

You can loosen a guitar string and lower the pitch to a point, but eventually it can’t get any slacker. The pitch won’t go any lower. In the same way, human vocal cords can only go so low and still sound “normal”. Once you get below a certain point, the vocal cords just re...
The glottal source was created by converting the pitch and timing information to a glottal source signal (0.1% noise was added to make the signal sound more natural). The duration of the source signal was 150 ms and the pitch fell linearly from 230 Hz at the onset to 200 Hz at ...
FIG. 4 is a diagram showing a relationship between the ground contacting length divided by groove pitch and noise level in decibels; FIG. 5 is a plan view showing a tread pattern used for examination, and FIG. 6 is a graph showing the waveform of the measured sound pressure thereof. ...
