Hypersonic® sound (HSS®) is an audio technology that uses the interaction between ultrasonic waves and air to generate audible sound. Human ears cannot detect ultrasonic tones. Traditional speakers generate sound by vibrating a fixed material that creates waves of pressure that travel through the air.

Can humans hear hypersonic?
The hypersonic effect is a phenomenon reported in a controversial scientific study by Tsutomu Oohashi et al., which claims that, although humans cannot consciously hear ultrasound (sounds at frequencies above approximately 20 kHz), the presence or absence of those frequencies has a measurable effect on their
What is hypersonic frequency?
The hypersonic frequency range corresponds to the frequencies of electromagnetic oscillations in the decimeter, centimeter, and millimeter ranges (the so-called superhigh frequencies, or SHF).
Can humans have ultrasonic hearing?
Ultrasonic hearing is a recognised auditory effect which allows humans to perceive sounds of a much higher frequency than would ordinarily be audible using the inner ear, usually by stimulation of the base of the cochlea through bone conduction.
What makes ultrasonic sound?
Crystals of materials such as quartz vibrate very fast when electricity is passed through them —an effect called “piezoelectricity.” As they vibrate, they manipulate the air around them and the fluids they come in contact with, producing ultrasound waves.
Is supersonic hearing real?
Hyperacusis is not “ super hearing” But what they do have is reduced tolerance and increased sensitivity to specific sounds and sound levels that are not normally regarded as loud.
What sounds can humans not hear?
Here are just a few sounds most people are missing out on:
- Sounds for young people.
- Music designed for cats.
- A dog-specific Beatles’ song.
- Ultrasonic finger friction.
- Infrasonic elephant calls.
What sound frequency is harmful to humans?
The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.
What frequency is ultrasonic?
Sounds with a frequency of 20 kHz and higher are referred to as ultrasound (or ultrasonic sound). High frequency sound is sound of which the frequency lies between 8 and 20 kHz. High frequency sound with a frequency over 16 kHz can hardly be heard, but it is not completely inaudible.
What does the word hypersonic mean?
1: of or relating to speed five or more times that of sound in air — compare sonic. 2: moving, capable of moving, or utilizing air currents that move at hypersonic speed hypersonic wind tunnel. Other Words from hypersonic More Example Sentences Learn More About hypersonic.
What happens if we hear ultrasonic sound?
“If you’re in the zone [of an ultrasonic sound] and you’re one of the sensitive people, you’ll get headaches, nausea, tinnitus [ringing in the ears ] and [various other symptoms],” Leighton said. “And once exposure stops, you recover.
Is ultrasonic sound waves harmful to humans?
Although Ultrasound cannot be heard by humans, at high decibels it can still cause direct damage to human ears. Ultrasound in excess of 120 decibels may cause Hearing damage. Exposure to 155 decibels causes heat levels that are harmful to the body.
Who can listen ultrasonic sound?
Bats, Insects like beetles, moths, praying mantis, dolphins, dogs, frogs and toads, etc. communicate using ultrasonic hearing. Infrasound, is a low-frequency sound less than 20Hz.
What are the examples of ultrasonic sound?
An example of ultrasonic is a dog whistle that cannot be heard by humans, An example of ultrasonic is the detection of ships and objects underwater by bouncing a high frequency sound wave off their hulls, a process discovered by Paul Langevin, a Frenchman.
What are the methods to produce ultrasonic waves?
There are three methods for producing Ultrasonic waves. They are: (i) Mechanical generator or Galton’s whistle. (ii) Magnetostriction generator. Merits:
- Magnetostrictive materials are easily available and inexpensive.
- Oscillatory circuit is simple to construct.
- Large output power can be generated.
