Ultrasonic vs. Hypersonic: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on November 22, 2023
Ultrasonic refers to sound frequencies above the range of human hearing, while hypersonic pertains to speeds exceeding five times the speed of sound.

Key Differences

Ultrasonic and hypersonic represent two distinct realms within physics. While ultrasonic is related to sound and its frequency, specifically those beyond the human range of hearing, hypersonic concerns itself with speeds, specifically those that are five or more times faster than the speed of sound.

In the realm of acoustics, ultrasonic frequencies are those that exceed the human hearing range, typically above 20 kHz. These frequencies are utilized in various technologies such as medical imaging and sonar. On the other hand, hypersonic refers to aerodynamic speeds and is often used in aerospace contexts, denoting velocities that are multiples of the speed of sound.

An ultrasonic wave can travel through various mediums, including air, water, and solid materials, often used in applications like cleaning delicate items or detecting flaws in metals. Meanwhile, hypersonic speeds, which start from Mach 5, represent challenges for engineers, especially in the design of aircraft, due to the immense heat and pressure at such velocities.

It's important to understand that while ultrasonic describes a kind of sound wave that cannot be heard by humans, hypersonic describes an object or phenomenon moving at extreme speeds. The former is about frequency, and the latter is about velocity.
