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 much louder is 80dB than 60dB?
quite loud.
A sound of 20 dB intensity is twice as loud as one of 10dB?
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.

Louder at 800 Hz 50dB or 600 Hz 30dB?
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.
Do you have to have 100 percent hearing to be a pilot?
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.
If power is decreased from 6 milliwatts to 6 microwatts the change in power level expressed in decibels is?
Approximately 30dB down.Exactly 30dB down. Or -30dB.
