The quietest sound that a human ear can typically detect is around 20 decibels, which is equivalent to the sound of leaves rustling or a ticking watch in a quiet room.
The threshold of hearing, or the quietest sound humans can hear, is typically around 0 decibels (dB) at a frequency of 1,000 hertz. Sounds below this threshold may not be perceivable by the human ear.
The quietest sound ever recorded is generally considered to be around 10-20 decibels, which is close to the threshold of human hearing. This level of sound is almost imperceptible and is often associated with the quietest environments or the sound of atoms moving.
The animals that make the quietest sounds are the ones that humans can't hear. These typically include animals like rattle-less snakes.
The quietest sound ever made is believed to be around 0 dB, which is the threshold of human hearing. At this level, sound waves are essentially non-existent and cannot be detected by the human ear.
The human auditory threshold (absolute threshold of hearing) is a sound pressure of 20 µPa (micropascals), at 1000 Hz, as determined by the RMS (root mean square) method*. It is, as close as can be determined, the quietest sound that human hearing can detect.* This is an average, so by definition, at least some of the subjects probably were able to hear slightly quieter sounds.

Does a heart make decibels? Never heard a heart.
The generally accepted threshold of hearing is around 0 decibels, which corresponds to the quietest sound that can be detected by the average human ear in ideal conditions. However, this can vary depending on the individual's hearing sensitivity and external factors.
The threshold of hearing is typically around 0 decibels (dB), which is the quietest sound that can be detected by the human ear under ideal conditions. However, this can vary depending on individual differences and frequencies.
