Sensurround pseudorandom number generator circuit on the patent, to create low frequency rumble. The original Sensurround design used for Earthquake employed a pseudorandom noise generator , designed by D. Broadus "Don" Keele, Jr., to create the low-frequency rumble, using recordings of the 1971 Sylmar earthquake as a reference. [ 3 ]
The Hum is a name often given to widespread reports of a persistent and invasive low-frequency humming, rumbling, or droning noise audible to many but not all people. Hums have been reported all over the world, including the United States, the United Kingdom, Australia and Canada.
In this system all the low-frequency rumble was in the left channel and all the high-frequency distortion was in the right channel. Over a quarter of a century later, it was decided to tilt the recording head 45 degrees off to the right side so that both the low-frequency rumble and high-frequency distortion were shared equally by both channels ...
A rumble is a continuous deep, resonant sound, such as the sound made by heavy vehicles or thunder. [1] In the context of audio reproduction rumble refers to a low frequency sound from the bearings inside a turntable. This is most noticeable in low quality turntables with ball bearings. Higher quality turntables use slide bearings, minimizing ...
Although the ear is the primary organ for sensing low sound, at higher intensities it is possible to feel infrasound vibrations in various parts of the body. The study of such sound waves is sometimes referred to as infrasonics , covering sounds beneath 20 Hz down to 0.1 Hz (and rarely to 0.001 Hz).

A "rumble filter" is a high-pass (low cut) filter with a cutoff typically in the 20 to 40 Hz range; this is the low frequency end of human hearing. "Rumble" is a type of low-frequency noise produced in record players and turntables, particularly older or low quality models.
