What is the minimum distance of the obstacle from the source to hear an echo?

The minimum distance for an echo to be heard is approximately 17.2 meters (56.4 feet) from the source. This accounts for the time it takes for sound to travel to the obstacle and then reflect back to the source for the echo to be perceived.


What is the farthest a human can hear underwater?

How far away can a human hear sounds?

The distance at which a human can hear sounds depends on various factors such as the volume of the sound, the environment, and the individual's hearing ability. Generally, a human can hear sounds from a distance of up to 20 feet away in a quiet environment. However, this distance can vary significantly in different situations.


How far can humans hear sounds in their environment?

Humans can typically hear sounds in their environment up to a distance of about 20 feet, depending on factors such as the volume and frequency of the sound.


What is the minimum distance to get an echo?

Depends on the quality of the sound. The minimum distance to hear an echo will be partly based upon the observers ability to resolve different sounds (i.e. so that they can distinguish between the actual noise, and the arrival of the reflected sound - a little 100 year old lady may not be as good as a 15year old!). This will vary between observers, as their auditory reaction times vary In the perfect Physics world though: Assuming a sharp sound (like a gunshot) the minimum distance (d=vt) to hear distinct echo is 17.2m considering the speed of sound to be 344ms. In general the "minimum echo distance" is always equal to half a wavelength from the reflector.
