Feelings are different from person to person. So don't talk of "measuring" the "loudness". You can really measure the sound pressure with a sound pressure level meter. At 8 ft from the speaker sound pressure level (SPL) is 28 decibels. What is loudness 4 ft from the speaker? You get 6 dB more level at half the distance r = 1/2, that is 34 dB. The sound pressure varies with distance 1/r from the sound source. There is nothing squared! Scroll down to related links and look at "Sound pressure p and the inverse distance law 1/r".
What else can I help you with?
Loudness is measured in decibels were the threshold of pain 120 decibels What does this mean?
That means, a higher sound pressure let you ears ache. You can become deaf.
Decibels of human voice?
Loudness of normal adult human voice is about 70 db at three feet according to http://www.businessdictionary.com/definition/decibel-dB.html
Which loudness measure unit?
The unit of loudness N is "the sone" and the unit of loudness level (volume) LN is "the phon". Scroll down to related links and look at "Conversion of sone to phon".
Gradual increase in loudness?
crescendo
80 decibels is how many times louder than 60 decibels?
The sound pressure level of 80 dB is a 10 times higher measure than the sound pressure level of 60 dB. Louder ist not the correct word, because it belongs to psycho acoustics and tells the loudness feeling.
Which element of music is measured in decibels?
The loudness or volume of music is measured in decibels. Decibels are a unit used to quantify the intensity of sound.
What is loudness measured with?
Decibels
What loudness increased by?
Decibels?
Loudness or sound level is measure in units called?
Loudness or sound level is measured in units called decibels (dB).
Decibels are a measuremeant of what?
Decibels are a measurement of the loudness of sound.
How do decibels measure loudness?
Decibels measure loudness by quantifying the intensity of sound waves. The higher the decibel level, the louder the sound.
What is the relationship between the distance from the source and loudness?
The relationship between distance from the source and loudness is that as distance increases, the sound intensity decreases, resulting in lower perceived loudness. This follows the inverse square law, meaning that the sound intensity is inversely proportional to the square of the distance from the source.
What measures the loudness of a sound wave?
decibels
What is the unit of measurement for the loudness of the sound?
Decibels
Is decibel a unit of loudness?
Decibels are a unit used to measure the intensity or power level of a sound. While it is commonly associated with loudness, decibels specifically quantify the level of sound pressure.
Is the measure of loudness frequency or decibels?
The measure of loudness is typically quantified in decibels (dB). Frequency, on the other hand, refers to the pitch of a sound and is measured in hertz (Hz).
What is loudness and distance?
Loudness is the perceived intensity of sound, measured in decibels (dB). Distance affects loudness by causing sound to decrease in intensity the further it travels, as sound waves disperse in all directions. The inverse square law states that the sound pressure level decreases by 6 dB for each doubling of distance from the sound source.
