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 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 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.
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.

The animals that make the quietest sounds are the ones that humans can't hear. These typically include animals like rattle-less snakes.

I have a 1.5 cu ft. Samsung and I can barely hear it.
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.

The quietest thing in the world is considered to be a vacuum. In a vacuum, there is no air or matter to carry sound waves, so sound cannot travel through it. This absence of sound makes a vacuum the ultimate quiet environment.
The superlative form of the word quiet is quieter
The quietest room in the world record is held by an anechoic chamber at Orfield Laboratories in Minnesota, USA. This room has been measured to have a sound level of -9.4 decibels, making it extremely quiet and almost completely devoid of any sound.
