A decibel is a unit used to measure the?
decibels measure the intensity of sound.
How loud is the loudest alarm clock?
Sound is measured in decibels. Decibels are units used to measure the intensity of sound. The highest decibel alarm clock available is 120 decibels, which can be compared to be as loud as the sound of a fire engine siren.
What units are used to measure sound energy?
The total energy in a specific sound can be measured but that is not the normal way of reporting sound energy.Sound energy is typically characterized as power (energy per unit time) per unit area. The standard units (SI) of sound intensity are W/m2 (watts per square meter).When sound is measured by a sound meter, the result is often reported as a "Sound intensity level" that is expressed in decibels and compared to a defined standard of one picowatt per square meter.There are other measures, such as "sones" which are meant to characterize perceived loudness, but that it not a standard (SI) measure.In standard units then, total energy would be joules, power would be watts, intensity would be watts per square meter.
What units are used to measure sound loudness and softness?
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness".
What are decibels a measure of?
The intensity of sound is measured in a unit called the decibel (dB), which describes the relative intensity of a sound based on an algorithmic decibel scale containing values ranging from 0 to 194. A zero value on the decibel scale represents the weakest sound audible to humans and sound intensity increases in correspondence with numeric values, the relationship among the values on the decibel scale is not linear but algorithmic. Here is an example of the decibel scale http://www.explainthatstuff.com/soundlevelmeters.html
What instrment measures the intensity?
A sound level meter is used to measure the intensity of sounds, typically in units of decibels (dB). It consists of a microphone to pick up the sound and electronic circuits to convert the sound into a digital display of the intensity level.
Which of the units is used to measure intensity of noise?
"Decibels"
Is a measure of loudness or intensity of sound?
Sound pressure level (SPL) is a commonly used metric to quantify the loudness or intensity of sound. It is expressed in units called decibels (dB) and provides a relative measure of how powerful a sound wave is compared to a reference level. SPL values are logarithmic, meaning a small change in dB corresponds to a significant change in sound intensity.
What are the units used to measure sound pressure levels?
The units used to measure sound pressure levels are decibels (dB).
A decibel is a unit used to measure the?
decibels measure the intensity of sound.
What is a unit used to measure the intensity of sound called?
decibel
What is the name of the unit used to measure the intensity of a sound?
a decibel
What is a decibel level?
A unit used to measure the intensity of a sound or the power level of an electrical signal. Someones voice could raise by a decibel.It is used to measure the sound intensity and loudness.
What is the unit used to measure the relatice intensity of sound?
Your ears and the sound pressure level meter "measure" the sound pressure of a sound wave. Sound intensity is measured in watts per square meter.Intensity is measured in watts per square meter.Note: Sound power (sound intensity) is the cause -and the sound pressure is the effect.The effect is of particular interest to the sound engineer.
What is the scale used to define sound intensities?
Sound intensities are typically measured in decibels (dB), which is a logarithmic unit used to quantify the intensity of sound. The decibel scale compares the intensity of a sound to a reference level, usually the threshold of human hearing.
What is the unit of sound and light?
Several units are used, depending on what you want to measure. For example, in the case of sound, you can use units of energy, of intensity (energy/area), of wavelength, frequency, speed, and probably a few more.
How is loudness measured and what units are used to quantify it?
Loudness is measured in decibels (dB), which quantify the intensity of sound. A sound level meter is typically used to measure loudness, with higher decibel values indicating louder sounds.
