【實用工具app】Leak Detector|最夯免費app-綠色工廠好玩App

Find compressed air leaks using your cell phone! Leak Detector uses your phone's built in microphone to listen for high frequency sound in a narrow band around 20 kHz, then plays it back at lower frequencies.

Listen to almost anything that's happening just above the range of human hearing!

What will it hear?

• Turbulence

• Friction

• Impact

• Very high frequency chirps and whistles

What will it ignore?

• Normal conversation

• Most ambient noise

Just position your device's microphone within a couple feet of a suspected leak, press Listen, then watch the red/green indicator, and listen for the tell-tale hiss. Small leaks may require close proximity. Larger leaks can be detected farther away. Use of headphones that do not have a built-in microphone is highly recommended.
