0 dB is the threshold of hearing. Some people can hear a very soft sound and some cannot hear anything.

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
What is captured zero?
your mom has captured zero
What is the definition of a pointer on a triple beam balance?
It is to show you that the pointer is on the zero mark.
What is the word form for 1.003?
One point zero zero three
What is the average weight of a shed?
The shed is of zero mass and zero weight
A sound of zero decibles cannot be heard and is considered infrasonic?
Zero decibels doesn't exist in the nature, on the earth; zero noise is any sound waves.
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) .
The absolute threshold for hearing is arbitrarily defined?
The absolute threshold for hearing is defined as the lowest intensity of a sound that can be detected by an individual at least 50% of the time. While specific measurement criteria may vary, this threshold serves as a practical reference point for understanding auditory perception.
What is the minimum intensity a sound can have?
The minimum of sound intensity can be theoretically as low as zero decibels. But you seem to mean what the human threshold of hearing is. That reference sound intensity is 10^−12 W/m² equal to 0 dB sound intensity level. Our eardrums are moved by the sound pressure. The reference sound pressure at the human threshold of hearing is po = 20 µPa equal to 0 dB sound pressure level (SPL).
What causes two sound waves to combine and produce no sound?
This is known as 'Sound Cancellation' or deconstructive interference. It occurs when two waves 180º out of phase of and of equal magnitude combine. The resulting wave has zero magnitude and thus cannot be heard.
Does the frequency of a whales sound made underwater changes after being heard in air?
When a sound passes from one medium to another of different [non-zero] density, its speed and wavelength change, but its frequency doesn't. It doesn't matter what either medium is, or what source produced the sound.
In the story a noiseless flash how did john hersey blend fiction and nonfiction in hiroshima?
Most of the survivors did not hear the sound but did see the flash. The ones that heard it were far from ground zero.
Is ground zero haunted?
i have heard rumors and people have been seeing things but there isnt no evidence that it is haunted but we will find out in the future
How do you say 0000 hours in words?
Zero hundred hours if you want to sound military. Normal people would just say midnight.

What the smallest amount of sound is that can be heard?
Zero dB is the quietest sound that may be heard by the average of a group of young men who have not been noise exposed. By definition, one half of these will be able to hear a quieter sound, and the other half will be less sensitive. Nowadays, these limits are more precisely defined in terms of physical units. Some animals hear at a different sensitivity to us, and over a different frequency range.
How many people live in Pompeii?
Zero people live in Pompeii today, or so I've heard. But just to be sure look on Google.
