how far can humans hear

The range of human hearing is typically considered to be between 20 Hz and 20,000 Hz. This means that humans can hear sounds with frequencies as low as 20 vibrations per second (very low rumbles) and as high as 20,000 vibrations per second (very high-pitched sounds).

In terms of distance, the range of human hearing depends on various factors such as the intensity of the sound, the frequency of the sound, and the environment in which the sound is being heard.

Here are some general guidelines on the maximum distances at which humans can hear different types of sounds:

* Whisper: 1-5 meters (3-16 feet)
* Normal conversation: 5-10 meters (16-33 feet)
* Loud conversation: 10-20 meters (33-66 feet)
* Shouting: 20-50 meters (66-164 feet)
* Sirens or alarms: 500-1000 meters (1640-3280 feet)
* Explosions or gunfire: 1-5 kilometers (0.6-3.1 miles)

It’s worth noting that these distances are approximate and can vary greatly depending on the specific circumstances. For example, a person may be able to hear a whisper from a much greater distance in a quiet, enclosed space than in a noisy, open environment.

Additionally, some people may have more sensitive hearing than others, and may be able to detect sounds at greater distances. However, the general range of human hearing is typically considered to be within the distances listed above.
