What is the time interval between direct sound and reflected sound?

The time interval between direct sound and reflected sound is the time taken for the reflected sound to travel from the reflecting surface to the listener. This time interval depends on the distance between the reflecting surface and the listener.

The formula for calculating the time interval between direct sound and reflected sound is:

```

t = 2d/c

```

where:

* \(t\) is the time interval in seconds

* \(d\) is the distance between the reflecting surface and the listener in meters

* \(c\) is the speed of sound in meters per second

For example, if a reflecting surface is 10 meters away from the listener, the time interval between direct sound and reflected sound would be:

```

t = 2(10 m) / 343 m/s = 0.058 s

```

This means that the reflected sound would arrive at the listener 0.058 seconds after the direct sound.
