Echo Distance Calculator
〰 Oscillations & waves. Use the Echo distance formula to find distance to the wall, speed of sound, echo time: pick the value you want, type the others, and the answer updates as you go.
The sound goes there and back.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Distance to the wall | m |
| Speed of sound | m/s |
| Echo time | s |
Worked example
Find the distance to the wall when Speed of sound = 343 m/s, Echo time = 1 s.
Using d = vt/2: Distance to the wall = 171.5 m.
Frequently asked questions
What is the formula for Echo distance?
d = vt/2. The sound goes there and back.
What do the letters stand for, and what units are used?
Distance to the wall in m, Speed of sound in m/s, Echo time in s.
How do you calculate distance to the wall?
Put the values into d = vt/2. For example, with Speed of sound = 343 m/s, Echo time = 1 s, distance to the wall = 171.5 m.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (distance to the wall, speed of sound, echo time) and fill in the others: it rearranges the formula for you.
