100 times louder. You will hardly hear a 20 db(SPL) sound at all.

How many times louder is an 80 dB sound compared to a 40 dB sound?
1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.
How many times louder is a sound wave with a intensity of 83db than a sound wave with an intensity of 70db?
Use the definition of decibel. The factor can be calculated as is 10(83-70/10). = 101.3.
How many times louder is an air raid siren than a lorry?
8 times louder
How many decibel does a car produce?
It depends on how close at the car you measure the sound with a sound pressure level meter.
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.
How many decibels does the human heart make?
Does a heart make decibels? Never heard a heart.
What is the decibel level of animal speech?
dolphins make lots of diffrent noises cause they communicate.if they communicate, they make diffrent noises.
How many times louder is 100 dB that 10 dB?
A 10 dB sound pressure level (SPL) is 0.000063 pascal and 100 dB is 2 pascal. Loudness is a problematic psycho acoustic feeling. I don't know what three times louder really means.
How many decibels in one meter?
24dB Sound Pressure Level (SPL) is about the sound level in a calm room.
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
A sound that measures decibels is 1000 times louder than the threshold of hearing?
The threshold of hearing varies between individuals, but is commonly taken as 0dB. About one-half of the (undamaged, young, non noise-exposed, ... ...) people will have hearing better than the threshold, and the other half will hear worse than the threshold. But to the point, 10dB is 10 times, 20 dB is 100 times, and 30 dB is 1000 times.
What is the loudness of sound of the normal conversation?
The sound of a normal conversation is 60dB (decibels) and a close range jet is 140dB. This makes a jet at close range over 2 times as many decibels than a close range jet. The sound of a normal conversation is 60dB (decibels) and a close range jet is 140dB. This makes a jet at close range over 2 times as many decibels than a normal conversation. The above answer is FALSE: The decibel scale is logarithmic and thus a 140 dB sound would be 10^14 above 0 decibel; the 60 dB sound would be 10^6 above 0 decibel. Thus the close range jet is around 10^(14 - 6) = 10^8, or 100,000,000 times the loudness of a normal conversation.
