Infrasound is sound that is below the lower limit of human hearing, below 20 Hz, and ultrasound is above the upper limit of human hearing, above 20,000 Hz.Infrasonic Sound has a frequency less than the audible frequency range. Example.Quartz crystal (c) Infrasonic wave : A longitudinal elastic wave whose frequency is below the audible range i.e. Some of these weapons have been described as sonic bullets, sonic grenades, sonic mines, or sonic cannons. Infrasonic sounds are those which are below 20Hz. Whales also use infrasound to communicate over large distances, even hundreds of miles. You might have herd of animals using ultrasonic sound before. The eruption of the Fuego volcano located in Guatamala created infrasonic sound in excess of 120 decibels in the range below 10 Hz. Audible: any voice or sound you hear. Infrasonic, is sometimes referred to as low-frequency sound, this sound is lower in frequency than 20 Hz (hertz) or cycles per second, the "normal" limit of human hearing. Less than 20 Hz.Sources: Volcanoes, Earthquakes, etc.Ultrasonic Sound has a frequency greater than the audible frequency range. If the frequency of a sound is greater than 20 kilohertz, it is called ultrasonic sound or ultrasound. Sources: Bats, SONAR… For my physics 20 Sound Unit project.

Ultrasonic is considered an energy form generated by a longitudinal mechanical wave with one-dimensional propagation and frequency of vibration above 20,000 cycles per second (20 kHz) as shown in Figure 4. The particles of dirt, grease and dust get detached and drop out due to the high amount of frequency. Ex: Sometimes sound produced by bats, dolphins are ultrasonic. moths can hear the high frequency of bat and can escape from it. ultrasonic sounds have a frequency above the upper limit of human hearing. Earthquakes produce low frequency infrasound before the main shock waves begin which possibly alert the animals. Avalanches, volcanoes, earthquakes, ocean waves, water falls and meteors generate infrasonic waves. The roars and purring of big cats, like tigers, have some infrasound frequencies. Ultrasonic sounds are those which are above 20000Hz. An example of ultrasonic is an ultrasound image of an unborn baby. Bats, whales and other animals often use these sound wave ranges for echo location. More than 20000 Hz. Create your own unique website with customizable templates.

In this episode, we discuss the mysteries of infrasound and what are the possible effects made by these strange sound waves. Ultrasound—which we will discuss more throughout this lesson—is also undetectable because of the limitations of our ear. Sources: Bats, SONAR, etc. Some sources of man-made infrasound are nuclear and chemical explosions, engines, machinery and airplanes (Figure 1). Lower sounds, in other words frequencies of 2-16 Hz, are called infrasonic. However, a good deal of noise may be present at 10 kHz, the first subharmonic frequency of the 20 kHz operating frequency, and is therefore audible to most persons. Some examples of ultrasonic … More than 20000 Hz. For example. 4 Hz needs as many as 120 decibels before we can pick it up. Ultrasound is no different from 'normal' (audible) sound in its physical properties, except in that humans cannot hear it. what is infrasonic and ultrasonic. Avalanches and meteorites also produce infrasonic waves, which are perceived as noise by some creatures.

This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy, young adults. Ultrasonic sound is when anything is above the frequenices of an audible sound. By definition, they have a long wavelength (from 17 meters at 20 Hertz up to 340 meters at 1 Hertz) Hertz) 1. Figure 1: Categorization of frequencies that are audible and inaudible to the human ear. Infrasonic is applied to sound that refers to sound waves below the frequencies of audible sound, and nominally includes anything under 20 Hz. Scientists have found newer applications in the field of medical sciences, notably being that of treating patients and conducting minor surgeries. The Tunguska event included seismic waves and infrasonic disturbances that were recorded around the world. Telekinesis and Quantum Field Theory . In addition to varying in physical description, infrasonic and ultrasonic sounds come from different sources. Ocean waves and storms generate a lot of infrasound. Less than 20 Hz.Sources: Volcanoes, Earthquakes, etc.Ultrasonic Sound has a frequency greater than the audible frequency range. It has frequency less than the audible frequency range. These sound waves are used as 'sound radar', recording and interpreting reflected sound to analyze tissues in medical sonography, and to conduct non-invasive scans of the body.
