as well as other psychological problems.However, psychologists distinguish between“sound”and“noise”.“Sound”is measured physically in decibels(分贝).“Noise”cannot be measured in the same way because it refers to the psychological effect of sound and its level of“intensity(强度)”depends on ...
Based on this estimation, it is possible to provide information about the reliability of a measured signal and whether the difference between intensities is mainly caused by noise or by biological relevant cellular alterations 展开 关键词: biomedical measurement maximum likelihood estimation medical signal...
However, psychologists distinguish between "sound" and "noise". "Sound" is measured physically in decibels. "Noise" cannot be measured in the same way because it refers to the psychological effect of sound and its level of "intensity" depends on the situation. Thus, for passengers at an ...
field intensity,field strength- the vector sum of all the forces exerted by an electrical or magnetic field (on a unit mass or unit charge or unit magnetic pole) at a given point in the field candlepower,light intensity- luminous intensity measured in candelas ...
The other physical factor that has been considered in recent years is sound. Noise/sound and light can affect the quality of human performance. Therefore, the aim of this study was to evaluate the intensity of light and sound in the Faculties of Babol University of Medical Scie...
Intensity noise spectra of LD pumped Nd:YVO4,Nd:YAG and Nd: YAP single- frequency ring laserare measured experimentally and compared with the spectra calculated with laserquantum model.The results show thatthere is an intensity noise about tens d B higher than the shot noise level(SNL) at the...
The noise characteristics of a 1.3 μm InGaAsP/InP laser diode were measured together with spectrum characteristics applying modulation and wide range quantitative reflection for the first time. The portion of reflected light which is fed back to the active region by a near mirror is estimated by...
The relative intensity noise (RIN) spectra of DC driven 1.3 μm distributed feedback laser diodes under the influence of external reflections are measured for various currents and reflection lengths. The effective power reflectivities are 3×10^lt-4gt-3×10^lt-3gt. The enhanced noise is obser...
