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 in the world is generally considered to be around 0 decibels, which is the threshold of human hearing. At this level, the sound would be so faint that it would be very difficult, if not impossible, to perceive.
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.
