On the decibel scale an increase of 10 decibels means an intensity increase of times?
10 decibels increase mean measured on a sound pressure level meter. SPL meter. Forget the intensity, because the ear drums and the microphone diaphragms are moved by the sound pressure. 10
How much is 110 decibels?
110 decibels means (1011 or 100,000,000,000) times as much as you started with.
I have 15 subwoofers at 180 decibels each how loud would that be in db in case your wondering yes there is a woofer that reaches 180db its called dd 9918Z 18?
15 subwoofers would produce 15 times as much power. log1015 = 1.176; to convert that to decibels, you have to multiply it by 10, so you get an increase of 11.76 decibels, in other words, 180 + 11.76 = 191.76 decibels. Since the 180 decibels probably includes some rounding, it makes sense to round the final result, too - for example, to 192 decibels.
Is a sound that measures 100-dB ten times louder than a 10-dB?
90
How is the volume in math alike to the volume of music?
Volume in math means the amount of space an object occupies. Volume in music means amplitude, loudness, or sound pressure. Scroll down to related links and look at "How many decibels (dB) is twice (double, half) or three times as loud?".
On the decibel scale an increase of decibels means an intensity increase ten times?
ten
On the decibel scale an increase of 10 decibels means an intensity increase of times?
10 decibels increase mean measured on a sound pressure level meter. SPL meter. Forget the intensity, because the ear drums and the microphone diaphragms are moved by the sound pressure. 10
Compared to a sound of 40 decibels a sound of 60 decibels is?
100 times intensity.
What is the si unit of sound intensity?
the sound intensity is measured in work /m .that means , si unit of sound intensity is decibel ( db) .
How does the intensity of a 40-decibel sound compare to the intensity 20-decibel sound?
100 times. Each bel (10 decibels) is ten times as loud thus 20 to 40 is 100 times.
How much is 110 decibels?
110 decibels means (1011 or 100,000,000,000) times as much as you started with.
Which is louder 60 or 70 decibels?
40 dB gain change should give about the ratio of 16 for sensed volume and loudness, 40 dB gain change gives the ratio of 100 for measured voltage and sound pressure and 40 dB gain change gives the ratio of 1000 for calculated sound power and acoustic intensity. Go to the link: Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power).
Is 30 dB 30 times greater than the thresholds of hearing or 103?
Assuming 0 decibel is approximately the threshold of hearing (different scales are sometimes used!), 103 is the correct answer. Every 10 decibels means an increase by a factor of 10, so 30 decibels means you have to apply the factor of 10 3 times: 10 x 10 x 10.
How do the amplitudes of a decibel sound a 100-decibels sound compare?
The power or intensity of the louder one is 10 billion times the power or intensity of the softer one. Since the power or intensity is typically proportional to the square of the wave amplitude, the amplitude of the louder one is a mere 100,000 times the amplitude of the softer one.
State the concept of the decibel?
A unit used to express relative difference in power or intensity, usually between two acoustic or electric signals, equal to ten times the common logarithm of the ratio of the power out to power in.
How loud is a decibel?
A decibel isn't a definite amount of anything. It's a unit used to compare two powers. 1 decibel more = 25.89% more power 3 decibels more = twice as much power 3 decibels less = half as much power 10 decibels more = 10 times as much power 10 decibels less = 0.1 as much power 20 decibels more = 100 times as much power You don't know how much any number of decibels is until you know what it's compared to.
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
