How Do Sound Wave Characteristics Affect What You Hear? So now that you know these different characteristics of sound waves, how does it affect what you actually hear? Well, there is a direct relationship between frequency and pitch and between amplitude and loudness. ...
Pitch is a characteristic of sound by which a correct note can be distinguished from a grave or a flat note. We can identify a female and male voice without seeing them. The term ‘pitch’ is often used in music. Pitch depends upon the frequencies of the sound wave. A note has a hig...
This paper elucidates mainly how to extract the pitch signals from speech sounds and how to indicate the pitch inflections by curves, and discusses further the characteristics of the pitch curves in Standard Chinese. The "maximum peaks" of voiced sound wave forms are extracted by means of the ...
The results for one example paragraph are listed in Table I, where each line corresponds to a perceived intermediate rhythmic unit, and the amount(G: ms)at the end of each line is measured duration of silent pause at that position, and the numerals under each Chinese character(syllable)repres...
In this paper, an attempt has been made to present the dynamic characteristics of a high-speed catamaran hull form. The two-dimensional strip theory method (using Lewis-form sections) has been used to predict the heave and pitch motions in frequency domain. Finally the response amplitude ...
The superimposition is mainly due to the interaction of the young swells propagated from the northern Red Sea and the local breezes prevailing along the coast at certain periods in a diurnal cycle. Based on the wave speed calculations and the estimated time shifts between the wind and waves, ...
In deep-sea mining, the coupling dynamic response between the mining vessel and the lifting pipe is a significant problem, which directly affects the structural design of the lifting system and the safety of field operation. The characteristics of couple
Furthermore, Fx.b (x-axis force at tower-base) and My.b exhibit obvious responses at the natural frequency of pitch motion. As the wave height increases, the wave-frequency response of the tower base load also strengthens, but the high-frequency response still accounts for a certain ...
shortcoming for PWM-based intermittent spray is the short lifetime of its solenoid valve due to frequent turning-on/ off for valve spool. However, this problem can be solved if a high-speed acting electromagnetic valve is chosen. (3) For PWM-based cont i nuous var i abl e spr ay,...
2.3 Pitch bearing design Because the NREL 5 MW reference wind turbine does not include a pitch bearing design, a design is specified as described in this section. The main restriction for the bearing design is the blade’s root dimensions. According to definition of 5 MW RWT [10], the...
