Why do the people sitting at a distance hear sound at the same time as the people sitting nearby?

This will only happen if the distances are not that great so the difference in time is so small that it is not detected. Sound travels a few hundred metres per second in air. An explosion heard a mile away will be about 5 seconds after those near the explosion hear it.

Can a loud sound be heard in a nearby room?
There are a lot of uncontrolled variables here. First of all, how loud is the sound? How thick are the walls? Is the door shut? At what frequency is the sound? But generally, people will be able to hear loud sounds in a nearby room.
Can you write a sentence using the word nearby?
There was a sound nearby but I couldn't make it out.
The pitch of a sound is the distance from the sound source?
The pitch of a sound means the frequency. That stays constant with distance. You mean the sound pressure level that decreases with distance.
Ways to measure sound from an distance?
to measure sound from distance use decibels
How can people observe the Doppler effect?
For example when firemen car passes around them. The sound is distorted according to distance in which the car is.
Why did my coffee make a buzzing sound when sitting on my desk?
You coffee might have made a buzzing sound when sitting on your desk from the vibration that went through the building. It could have vibrated against your desk and made this sound.
What distance is loudness of sound measured?
There is really no standard distance from the sound source where the sound pressure level (SPL) is measured.
What is the effect of distance on sound?
The sound pressure decreases with distance r in a free field (direct field).The next question is. How does the sound decrease with increasing distance? After which law?The sound pressure p diminishes with distance after the 1/r law. Sound pressure decreases inversely as the distance increases with 1/r from the sound source. The Sound pressure level (SPL) decreases by (−)6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.Sometimes it is said, that the sound decreases with with 1/r², the inverse square law. That is really wrong.Scroll down to related links and look at "Damping of sound level with distance".p2 / p1 = r1 / r2 and p2 = p1 x r1 / r2p1 = sound pressure 1 at reference distance r1 from the sound source.p2 = sound pressure 2 at another distance r2 from the sound source.Scroll down to related links and look at "How does the sound or the noise decrease with distance?"
What is the use sound to find distance?
Are you looking for the inverse distance law? How sound pressure decreases with distance? Scroll down to related links and look at "Sound pressure p and the inverse distance law 1/r".
Does the mars rover take in sound or distance?
sound
What distance is the loudest sound made by a spider?
At a very close distance to the spider you hear the loudest sound.
What effect does distance have on sound?
The sound pressure decreases with distance after the distance law 1/r. (No squre!) Our ear drums are only moved by the sound pressure of the air. Scroll down to related links and look at "Inverse Distance law".
