When doubling the field quantity factor by 2 the level increases by 6 dB.
When doubling the energy quantity factor by 2 the level increases by 3 dB.
When doubling the sound pressure value by 2 the level increases by 6 dB.
When doubling the sound intensity value by 2 the level increases by 3 dB.
The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity relative to a specified or implied reference level.
You usually don't double decibels - you double the factor (ratio).
Look at the link "Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power)".
What else can I help you with?
How many decibels does a cough produce?
70-100 decibels
You want to measure how much louder 95 decibels is than the threshold of sound?
Take a sound pressure level meter and measure it. 95 decibels means over the is 0 decibels is the threshold of hearing. 95 decibels means the measure over 0 decibels.
Normal conversation is usually about decibels while noise at decibels or higher can start to damage your hearing?
65; 85
How is volume related to decibels?
<p><p> Volume, as in sound volume, is measured in decibels.
How loud is the loudest alarm clock?
Sound is measured in decibels. Decibels are units used to measure the intensity of sound. The highest decibel alarm clock available is 120 decibels, which can be compared to be as loud as the sound of a fire engine siren.
What is the equivalent db level when listening to earphone or headphone volume?
dB is short for Decibel, or one tenth of a bel. Bels and decibels are unlike any other measurement, because an addition of ten means double the loudness of the noise. For example: 60 decibels is the noise generated from a regular conversation, however, 70 decibels is double the noise; and 80 is double that.
What is the recommended level of double hearing protection in decibels (db) for optimal hearing protection in noisy environments?
The recommended level of double hearing protection for optimal hearing protection in noisy environments is around 30 decibels (dB).
Why is the abbreviation for decibels dB?
DeciBels
What is the volume level measured in decibels of a sound that registers at 55 decibels?
The volume level of a sound that registers at 55 decibels is 55 decibels.
Does voltage current or power affect volume in a speaker?
Power (Watts)/ Decibels (if the speaker is efficient) 2 Watts = 93 decibels 4 Watts = 96 decibels 8 Watts = 99 decibels 16 Watts = 102 decibels 32 Watts = 105 decibels 64 Watts = 108 decibels 128 Watts = 111 decibels 256 Watts = 114 decibels 512 Watts= 117 decibels 1024 Watts = 120 decibels Some Volumes to Compare 10 decibels = normal human breathing 60 decibels = normal human conversation 110 decibels = power saw, car horn, shouting in ear, 120 decibels = jet aircraft close by, emergency vehicle siren, rock concert
