This app features precise low range sound frequencies that allow you to test the capabilities of your subwoofer speakers. Sound frequencies are measured in Hertz (Hz) and the frequencies included in this app range from 15Hz to 100Hz, with a test sound at each 5Hz increment. Including test sounds in 5Hz increments allows you to more accurately pinpoint the lowest range that your audio system can play. Humans can begin to hear tones at around 20Hz, so having an audio system with capabilities to play sounds lower than this typically isn't necessary!

All sounds and pitches are made up of frequencies at varying wavelengths, with lower sounds having a longer wavelength and higher pitch sounds having a shorter wavelength. Commercial speakers vary in quality and ability to play the lowest sound frequencies. Test your sound system today!

Make sure you are getting the most out of your music and not missing out on the low frequency bass sounds! Use these test frequencies to verify the audio capabilities of your car speakers, home sound system or personal headphones.

Turn up your bass and bump the lowest sounds possible!
