何謂聲音壓力,聲音功率與聲音強度(SoundPressure,SoundPowerandSoundIntensity) 聲音壓力,聲音功率與聲音強度 音波造成的壓力變化稱為聲音壓力p(SoundPressure)(Pa) 聲音是種能量,而單位時間所輸出的能量稱為聲音功率P(SoundPower)(W) 單位時間垂直通過單位面積的能量稱為聲音強度I(SoundIntensity)(W/m2) 何謂聲音壓力...
声功率Sound power level是声源单位时间内向外辐射的声能。以往使用声压值(sound pressure level)来描述产品、环境或噪音量大小的指标最为常见,但以此作为描述机器或者产品的噪音放射特性并不足够,主要是声压级会因为音源与测量位置变化而不同。若以声功率作为噪音辐射的标准则会避开这些变化,因为它是一个绝对的参数,是...
Sound Intensity, Power and Pressure Levels Sponsored Links Ad The Decibel Decibelis a logarithmic unit used to describe ratios of physical values like - like power, sound pressure, voltage, intensity and more. The decibel can be expressed as: ...
If you are new to the field of noise and vibration, the terms sound pressure, sound power, and sound intensity may be a bit confusing. This is understandable, as they are all commonly used, as well as interrelated.They are all often expressed in decibels, which can be confusing in it’...
Taipower claims that their simulation and assessment estimated that the sound pressure level at the nearest house would be 25.1 dB(A), while the low-frequency noise would be 22.0 dB(A), both within the EPA's daytime limit of 50 dB(A) and evening limit of 40 dB(A). Bad feng shui ca...
2.3 Sound power, pressure and intensity It is important to distinguish between the various measures of the magnitude of sounds: sound power level and sound pressure level. Sound power level is the power per unit area of the sound pressure wave; it is a property of the source of the sound ...
Question in the title... I see values stated like this and dont know whether they mean sound power level or sound pressure level: Noise level (ISO 2151): 66dB(A
