Finally, the ability to measure distance with your iPhone! Sonic Ruler allows you to instantly and precisely take measurements using a microphone and an earphone. Measurements can be taken with precision up to the length of your earphone cord.

Using Sonic Ruler is easy. Simply point the left earphone at the iPhone’s built in microphone and press the measure button and that’s it! The distance between the earphone and the microphone will instantly be displayed at the top of the screen.

Please note that the distance being measured is from the left earphone to the iPhone’s built in microphone, which is located at the bottom of the iPhone (see the illustrated instructions Screen Shot).

How does Sonic Ruler work?
Sonic Ruler uses a unique algorithm to emit a high frequency sonic pulse that is received by the microphone. Given the know speed of sound (approximately 1125 ft/s), the distance the sonic pulse has traveled can be computed by multiplying the speed of sound by the amount of time the sound has been traveling. Using this calculation, Sonic Ruler instantly computes the precise distance of your earphone from the microphone and displays this information.

There are only three simple steps to use Sonic Ruler:
1. Plug in your earphones.
2. Turn up the volume.
3. Point the left earphone at the microphone and press measure.

Please see the illustrated instructions screen shot for more information on how to use Sonic Ruler.

Following these three simple steps, the distance from the left earphone to the microphone will be displayed at the top of the screen. You can choose to display this information in inches, feet or meters. In addition, Sonic Ruler will graphically display the magnitude of incoming audio signal. Sonic Ruler can be calibrated to further increase the accuracy of your measurements.

**If you are not getting any measurements after initial installation of Sonic Ruler, TRY RESTARTING YOUR IPHONE**

**Use measurement results at your own risk**
