Speaker Delay Calculator

About This Calculator

This speaker delay calculator helps you determine audio delay time based on the distance between the speaker and the listener. It uses the speed of sound and is ideal for sound system setup, live events, and acoustic planning.

How It Works

The calculator assumes a constant speed of sound at 343 meters per second (m/s). Enter the distance in meters or feet, and it converts it to meters (if needed) before applying the formula:

Delay (ms) =
Distance in meters343
× 1000

Frequently Asked Questions

How do I calculate speaker delay based on distance?

Simply enter the distance in meters or feet. The calculator applies the formula using the speed of sound to return delay in milliseconds.

What is the speed of sound used in this calculator?

This tool uses 343 m/s, which is the standard speed of sound at 20°C in dry air.

Which distance units can I use?

You can input the distance in meters (m) or feet (ft). The calculator automatically handles the unit conversion.
