    examples of infrasonic and ultrasonic sound

    Infrasound is the range of sound pitches that are below human hearing bottom limits (under 20 Hz). Infrasound, sometimes referred to as low-frequency sound, describes sound waves with a frequency below the lower limit of audibility (generally 20 Hz).Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. HTRZ stands for number of vibrations per second. Whales also use infrasound to communicate over large distances, even hundreds of miles. STUPID - Smart Talented Unique Person In Demand. Figure 1: Categorization of frequencies that are audible and inaudible to the human ear. A sound of 100 Hz needs a volume of at least 23 decibels before we can hear it.
