The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity
50dB - 30dB = 20dB
3dB is decrease to half
20/3 = almost 7
so 30dB is 7 times more silent than 50
1000 times louder (i.e. the sound pressure is 1000x higer)

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.
quite loud.
No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.
It's 10 times louder. It is easily looked up.. Example of source: http://www.howstuffworks.com/question124.htm

Sound Pressure Level(dB SPL) response , based on Equal- Loudness contours( ISO 226:2003 rev) and the Original ISO Std( set for 40 phons), applied in correlation to Fletcher Edmund - for Psychoacoustics, show that 30 dB @ 600Hz in quieter than 50dB @ 800Hz. ( 3rd Octave diagram range 10Hz to 20 KHz.) . FFT /sound density and 3rd Octave are in line for this particular case.
You don't need 100% hearing. You must be able to clearly hear with both ears and your back turned towards the source, a regular conversational voice in a quiet room from a distance of 6ft.If your medical examiner decides to perform an audiometric speech discrimination test you must pass with scores better than:Your better ear at sound levels 500Hz, 1000Hz, 2000Hz, 3000Hz with 35dB, 30dB, 30dB, 40dB respectively.Your worst ear at sounds levels 500Hz, 1000Hz, 2000Hz, 3000Hz with 35dB, 50dB, 50dB, 60dB respectively.
Approximately 30dB down.Exactly 30dB down. Or -30dB.
Dual is usually louder due to less back pressure. The amount it is louder depends on how it's built.
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.
They are about the same, depending on the pistol. C02 has a tendency to be a little louder on certain pistols but not much difference.
get heavier gauge strings, than you can make it sound much louder

quite loud.
I believe blowing a butt trumpet will produce a sound much louder than the Roots Megasonic.
It can be either. Some gongs are much louder than others. Sirens vary in design. However, most of the sirens used today would be louder than any gong you are likely to encounter.
