The physical characteristics obtained by SCHUMANN in the partial tone structure of sound from wind instruments are shown in new and original research work. They hold for wood and brass instruments. By means of average value envelopes, which represent a superposition of all spectra of an instrument...
Sound physically consists of pressure waves created by vibrating objects, which travel through a medium (like air or water). Key physical characteristics include: • Amplitude: The magnitude of pressure changes in a sound wave, which relates to how “loud” a sound feels. • Frequency: The...
People found that L has the characteristics of hearing ear index characteristics in the experiment, The sound pressure level is expressed in an exponential form, and it can also accord with the human auditory resolving power objectively. The unit of sound pressure level is dB, which is a ...
METHOD FOR THE OPTIMAL TRANSMISSION OF COMMUNICATION HAVING ANY PHYSICAL CHARACTERISTICS, METHOD FOR OPTIMAL SOUND REPRODUCTION AND SYSTEM FOR REALISING THE SAME, AND METHOD FOR THE ACTIVE, THREE-DIMENSIONAL AND OPTIMAL LEVEL REDUCTION OF SIGNALS HAVING ANY PHYSICAL CHARACTERISTICS...
Experimental techniques where the characteristics of a SMM are evidenced are magnetization and AC susceptibility measurements, through experiments as a function of temperature, magnetic field, and frequency. Complementary, static heat capacity measurements may provide valuable information about electronic levels...

The mechanics of the physical material nature is the table with its characteristics of the important indicators. The elastic constants, wood density, making musical instruments is the choice of indicators panel resonance. In addition wood affected by mechanical vibration characteristics of sound vib ...
Timber by vibration sound different timber has its own unique vibration characteristics of the physical nature of the study wood-based panels to reach the application effect of the wood material, the key is to solve the alternative wood materials as a musical instrument manufacturing. To master the...
PHYSICAL MODELS OF THE VOCAL TRACT SOUND DIFFERENT WITH THE SAME SHAPE BUT DIFFERENT TEMPORAL CHARACTERISTICS AND VICE VERSA 来自 internationalphoneticassociation.org 喜欢 0 阅读量: 12 作者: T Arai 摘要: Two physical models of the human vocal tract have been successfully developed for producing ...
The eigenvalues e_{1,2} of M are given by complicated expressions. To highlight the physical characteristics of the two modes, it is convenient to expand the dispersion relations e_{1,2}=0 for low momenta, thus obtaining \begin{aligned} \omega ^2 =&\ 2 A k^2 + 4 k^2 \bar{\rh...
