The ___ of sound can be measured in decibels. A. intensity B. volume C. pitch D. tone 相关知识点: 试题来源: 解析 A。“intensity”强度,声音的强度可以用分贝测量;“volume”音量;“pitch”音高;“tone”语气,这里指声音强度,所以选 A。反馈 ...
Figure 1: Sound pressure, sound power and sound intensity can all be expressed in decibels (dB) even though they represent different measured quantities. The measurement units used in sound pressure, sound power, and sound intensity are different. Often the measurement unit is omitted ...
Sound Pressure Level In subject area: Engineering Sound pressure level is a logarithmic measure of the effective pressure of a sound relative to the threshold of human hearing (20 μPA) measured in decibels (dB). From: Energy Research & Social Science, 2019 ...
It’s important to note that the loudness of a sound is measured in decibels (dB) and is a relative measure that depends on the context and the source of the sound. The concept of “loudness” on a phone might refer to the maximum volume output of the device’s speaker, which is usu...
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 ...
The volume of a sound is measured in decibels (dB). This is a measure of intensity, which relates to the amount of energy in the pressure wave. Decibels are a measure of relative volume. They relate the intensity of a pressure wave to a normal or standard pressure. The greater the inte...
Sound Pressure Level | SPL Meaning, Measurement & Examples from Chapter 12 / Lesson 3 87K Learn the definition of sound pressure level and explore the SPL meaning. Explore examples of sound pressure levels, a db SPL chart, and how...
Sound intensity and pressure (the physical correlates of loudness) are measured in decibels (dB). A dB is a unitless figure that compares 2 values and is defined as the logarithm of the ratio of a measured value to a reference value, multiplied by a constant: dB = k log (Vmeasured/Vref...
That is why there is the advice: In sound recording try to avoid the use of sound power and sound intensity as sound energy sizes. How many decibels (dB) is the sound energy W = I×t×A in J = W×s? This question is asked quite rare. For calculations we use more the following ...
