Computer sonar to save energy.

You probably remember the old submarine movies when to find any vessels around them, they would send out a sound that sounded like a ping and then waited for the sound reflection to come back. That is what we are going to do. This should have a greater sensitivity (being all things are equal) than a traditional ping sensor.

Step 1 What's needed.

Computer with working sound card and speakers
Working microphone attached tot he computer.

Software depending on the operating system.
