The audio titled "Sine Wave at 30 Hertz" is a sonic experience characterized by a low-frequency oscillation. The sound, represented by a sine wave, is steady and consistent, vibrating at a rate of 30 cycles per second, which is represented by the unit Hertz (Hz). The audio is an embodiment of the 'Low Frequency Effects' or LFE, often used in audio production and sound design, providing a deep, rumbling sensation that resonates within the surroundings. The 30Hz frequency of the sine wave delivers a rich, immersive auditory experience, crafting a pulsating rhythm that can be felt as much as it is heard.
