What type of scale is the decibel scale?
The decibel scale is a logarithmic scale. Scroll down to related links and look at "Decibel - Wikipedia" and "Sound level meter - Wikipedia".
How are fractals and logarithms relate to the real world?
-- The shoreline of any coastal land is a fractal. -- The distant view of any mountain range is a fractal. -- Your eyes perceive changes in light brightness on a logarithmic scale. -- Your ears perceive changes in sound loudness on a logarithmic scale.
What instrument measures decibels?
Most famous is a SPL meter (Sound Pressure Level).
This varies but at sea level it measures 740 miles per hour?
Speed of sound.
Is a sound that measures 100-dB ten times louder than a 10-dB?
90

What db has no sound?
dB is a logarithmic scale, so the answer, basically, is negative infinity.dB is a logarithmic scale, so the answer, basically, is negative infinity.dB is a logarithmic scale, so the answer, basically, is negative infinity.dB is a logarithmic scale, so the answer, basically, is negative infinity.
What are some common logarithmic scales?
The Decibal scale for sound measurement is an example of a logarithmic scale. The Richter scale, the pH scale, the magnitude scale for stars, the multiplicative scales on a slide rule
How is intensity related to loudness?
Assuming we are talking about sound, intensity measures the power in a sound wave. Mathematically, it is the product of the sound pressure and the particle velocity, and is measured in watts per square meter. Loudness usually refers to the (subjective) perception of sound intensity by people. It is related to intensity, but also depends upon frequency. The human ear perceives increases in sound intensity roughly on a logarithmic scale, so for example the sound intensity needs to increase by about a factor of ten to create the perception that the sound is twice as loud. This is the motivation for the decibel system, which measures sound intensity on a logarithmic scale.
What is fullform of pH?
It's the amount of hydrogen ions. (P)otential of (H)ydrogen its a log based scale, a logarithmic scale earthquakes are logarithmic, so is sound pressure(decibles)
Another word for loudness of sound?
Sound is normally measured is naturally measured in decibels (dB) which is a logarithmic scale.
What measurement do you use to measure loudness?
decibles(db)you choose the right answer, don't worry bye xxx
What separates the scale into equal parts?
Equally spaced subdivisions. However, a scale need not be divided into equal parts. For example, the logarithmic scale which, among other things, is used to measure the volume of sound - in decibels. The musical scale is approximately logarithmic.
What would you use to measure sound?
You are looking for a Sound Pressure Level (SPL) meter. The meter will measure on a logarithmic scale in Decibels (dB) to give you a quantifiable numbers. You should look for one with both A and C weighting.
Is intensity directly proportional to loudness?
No - since sound (hearing) operates on a logarithmic scale. So to be twice as loud a sound must be 10 times as "intense".
The pH scale is used to?
The decibel scale is used to measure the loudness of sound.
How are fractals and logarithms relate to the real world?
-- The shoreline of any coastal land is a fractal. -- The distant view of any mountain range is a fractal. -- Your eyes perceive changes in light brightness on a logarithmic scale. -- Your ears perceive changes in sound loudness on a logarithmic scale.
