What is the difference between sound and ultrasound

The vibrations caused by the ultrasound shake apart the kidney stones, breaking them up. Materials can be tested for internal faults and cracks that could lead to the failure of a structure under certain conditions. Ultrasound imaging provides a quick method of detection and perhaps prevents serious accidents.

High frequency sound waves can be used to detect objects in deep water and to measure water depth. The time between a pulse of sound being transmitted and detected and the speed of sound in water can be used to calculate the distance of the reflecting surface or object. The process is very similar to ultrasound imaging. For deep water, 50 kHz is the preferred frequency. This is because water absorbs sound waves at a slower rate for low frequencies and the signal can travel farther before becoming too weak to use.

It can also be used for industrial purposes such as helping in the process of cleaning or speeding chemical reactions. Ultrasound can be used in the process of cleaning jewelry, optical lenses, dental and surgical instruments, and some industrial parts.

The difference between infrasound and ultrasound is that infrasound is the barely audible low-frequency sound that humans can hear whereas ultrasound is the barely audible high-frequency sound. Both sounds are towards the ends of both sides of the human hearing frequency range , it is very difficult for humans to hear.

Therefore, infrasound and ultrasound may be inaudible to many people. Infrasound can affect our ears in different ways. Sometimes, infrasound can cause general discomfort because hair cells are most sensitive to frequencies below 30 Hz even though they may be inaudible. Moreover, infrasound may cause endolymphatic hydrops, which can cause the ear to swell and may even cause vertigo, tinnitus, and more. These low-frequency sounds may even cause noise-induced hearing loss.

Infrasound not only causes feelings of discomfort, but it can also have physical effects, such as breathing and digestive problems. People who live too close to wind turbines may experience some of these effects.

Ultrasound may also contribute to hearing loss especially if the ultrasound is very strong. It may also cause dizziness, migraines, vomiting, and nausea. Therefore, it is important to limit exposure to ultrasound-emitting devices for long periods of time to protect your hearing.

Remember, it is important to be proactive in protecting and maintaining your hearing health. Loud noise exposure can be very damaging, so make sure that you are doing what you can to minimize risks for hearing loss, such as wearing earplugs at loud events and keeping volume in your environment at a safe level.

We hope you enjoyed reading about the difference between infrasound and ultrasound and how you can take preventative steps to ensure that you have healthy hearing. But not all sounds are audible. For instance, ultrasound is not. Musicians call that frequency the pitch. Human ears can hear anything between 20 and 20, hertz. Waves with a higher frequency are known as ultrasound.

Those higher pitches are beyond human hearing. Sounds below human hearing are known as infra sound. In air, sound travels at a constant speed. That wavelength is the distance from the peak of one wave to the peak of the next. Long waves sound low and short waves sound high. Waves of the same frequency can differ in the amount of energy they carry. Sound waves with higher peaks, or bigger vibrations, carry more energy than those with lower peaks.

Within the range of human hearing, for instance, we perceive sound waves with higher peaks as louder. For many decades, medicine has relied on ultrasound to picture soft tissues inside the body.
