You can't hear this 7 Hz subwoofer test tone without extremely deep bass subwoofers. Sometimes called sub-sonic or infrasound audio, this sine wave because it is below the threshold of hearing. By request, this is a good subwoofer test and with capable speakers the sound could felt rather than heard.
Listeners will know the sound is present because there is a popping sound when pausing and starting the audio due to the 7 Hz waveform snapping back to the 0 position.
