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.
How loud is 90 db?
90 dB is considered very loud and can cause hearing damage with prolonged exposure. It is equivalent to the sound of a motorcycle or a lawnmower from a close distance. It is recommended to use ear protection in environments where the noise level reaches 90 dB or higher.
How many times more intense is a 90 dB sound than a 60 dB sound?
A 90 dB sound is 1,000 times more intense than a 60 dB sound. This is because the decibel scale is logarithmic, with every 10 dB increase representing a tenfold increase in intensity.
If sound A has an intensity that is 100 times that of sound B then how many dB's higher is sound A?
Sound A would be 20 dB higher than sound B. Sound intensity level (in dB) increases by 20 log (I1/I2) when the intensity ratio changes by a factor of 10. Since A is 100 times greater than B, the dB difference would be 20 log (100) = 20 dB.
What is a decibel of a bullhorn?
It depends on how loud it's being played.
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 distance increase is needed to reduce a sound's intensity from an initial 100dB to a final 80dB?
Sound intensity is inversely proportional to the square of the distancefrom the source.-- Increase the distance from the source by 10 times.-- Sound intensity decreases to 1/102 = 1/100 .-- 10 log ( 1/100 ) = -20 dB-- 100 dB - 20 dB = 80 dB
What is the decibel of a chainsaw?
The sound pressure level in decibels depends on the distance to the chainsaw. In 1 m distance we can get 110 dB. In 10 meters distance we get 90 dB. So keep off the noise maker.
How loud is 90 db?
90 dB is considered very loud and can cause hearing damage with prolonged exposure. It is equivalent to the sound of a motorcycle or a lawnmower from a close distance. It is recommended to use ear protection in environments where the noise level reaches 90 dB or higher.
Is a sound that measures 100-dB ten times louder than a 10-dB?
90
How many times more intense is a 90 dB sound than a 60 dB sound?
A 90 dB sound is 1,000 times more intense than a 60 dB sound. This is because the decibel scale is logarithmic, with every 10 dB increase representing a tenfold increase in intensity.
How loud is a panda on a decibel scale?
This is a typical wrong believe that a panda has 100 dB, a jackhammer has 110 dB, and a rock band must have 120 dB. Every one seems to be content with these wrong numbers. If there is no given distance with the measured decibel value, such numbers are really nonsense. With doubling the distance from a sound source the decibels decrease by 6 dB. So a panda sound can be at 12.5 m distance 110 dB. At 25 m distance 104 dB, at 50 m distance 98 dB and at 100 m distance only 92 dB. You see how important it is to tell always the distance with the measured decibel level. Don't believe that only a specific decibel value belongs to noise source.
If sound A has an intensity that is 100 times that of sound B then how many dB's higher is sound A?
Sound A would be 20 dB higher than sound B. Sound intensity level (in dB) increases by 20 log (I1/I2) when the intensity ratio changes by a factor of 10. Since A is 100 times greater than B, the dB difference would be 20 log (100) = 20 dB.
What decibel level is created by a helicopter?
If I say: Level of a helicopter = 130 dB, most people are content. Laymen think that a specific decibel value belongs to a noise source. Like heavy truck = 100 dB, jackhammer = 110 dB, rock band 120 dB. That is not correct. Alway is forgotten that the distance from the sound source to the measuring point plays an important role. Sound level decreases by (−)6 dB per doubling of distance from the source. Without any distance a dB value is really nonsense.
How loud is a jet engine in decibels?
This is a typical wrong believe that a jackhammer has 110 dB, a rock band has 120 dB and a jet engine must have 130 dB. Every one seems to be content with these wrong numbers. If there is no given distance with the measured decibel value, such numbers are really nonsense. With doubling the distance from a sound source the decibels decrease by 6 dB. So a jet engine sound can be at 12.5 m distance 130 dB. At 25 m distance 124 dB, at 50 m distance 118 dB and at 100 m distance only 114 dB. You see how important it is to tell always the distance with the measured decibel level. Don't believe that only a specific decibel value belongs to noise source.
How loud is 60 db?
60 dB sound pressure level is about conversational speech listened in 1 meter distance.
What is a decibel of a bullhorn?
It depends on how loud it's being played.
