Given: Sound intensity level LI = 150 dB.
Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing)
Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level)
Get sound intensity I when entering sound intensity level LI = 150 dB:
I = Io×10^(LI/10) in W/m² = 10^−12×10^(150/10) = 1000 W/m².

Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing)
Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level)
Get sound intensity I when entering sound intensity level LI = 70 dB:
I = Io×10^(LI/10) W/m² = 10^−12×10^(70/10) = 0.00001 W/m².

What is sound intensity measured in?
Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). The sound intensity I is measured in watts per meter squared. The sound intensity LI level is measured in decibels (dB).
How loud is 45 - 50 decibels?
The sound pressure of 45 dB is about a quiet library and 50 dB is about an everage home.
Sound measured in?
If you would like to measure how loud the sound is, dB, decibels, would be good. To give you a rough idea, a whisper is about 30 dB, a baby crying loudly about 100 dB. Also, if you like to measure the frequency or the wavelength, you can use Hertz.
How loud is 1000 db?
That's the sound of the Earth disintegrating.
How is the intensity of sound measure?
You take a measuring microphone with a sound pressure level meter.
How many time more is the orchestra than the soloist if the orchestra has a sound intensity of 90 db and the soloist has a sound intensity of 70 db?
The difference in sound intensity between the orchestra and the soloist is 20 dB. Since the decibel scale is logarithmic, a 10 dB increase represents a doubling of sound intensity. Therefore, the orchestra is 100 times louder than the soloist.
What are two types of sound and their approximate decibel levels?
A normal conversation is about 70 decibels (dB). A gun firing off is about 140 dB.
Which is louder 70 dB or 90 dB?
90 > 70
Where Is The D Flat In The saxophone?
The concert Db (meaning, the sounding Db, like it would sound on the piano) is Bb. The instrument's Db is C#.
What is the Sound in measure is what unit?
If you would like to measure how loud the sound is, dB, decibels, would be good. To give you a rough idea, a whisper is about 30 dB, a baby crying loudly about 100 dB. Also, if you like to measure the frequency or the wavelength, you can use Hertz.
How does intensity of a 40 decibel sound compare to intensity if a 20 decibel sound?
The 40dB sound is (40 - 20) = 20 dB louder than the 20 dB sound.20 dB louder = 10(20/10) = 102 = 100 times louder
When was The Sound of Music - The dB's album - created?
The Sound of Music - The dB's album - was created in 1987.
How loud is 60 db?
60 dB sound pressure level is about conversational speech listened in 1 meter distance.
Normal speech measures 60 dB A busy street measures 70 dB How many times louder is the busy street than normal speech?
70 dB is 10 times louder than 60 dB.
How much louder is a sound wave that has an intensity of 50 dB than a sound wave with an intensity of 20 dB?
A sound wave with an intensity of 50 dB is 1,000 times louder than a sound wave with an intensity of 20 dB. This is because every increase of 10 dB represents a 10-fold increase in intensity.
What is sound mesured in?
Sound is measured in units called decibels (dB). Decibels quantify the intensity or loudness of sound and are used to compare different levels of sound from quiet to loud.
What do you measure noise in?
If you would like to measure how loud the sound is, dB, decibels, would be good. To give you a rough idea, a whisper is about 30 dB, a baby crying loudly about 100 dB. Also, if you like to measure the frequency or the wavelength, you can use Hertz.
