What Is Hypersonic Sound?

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.

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.

Is sound beaming real?

This is an entirely new type of sensory listening that will change the way people experience audio. With SoundBeaming you can hear audio from a variety of sources privately and without disturbing others. And because the sound is beamed directly outside the ears, listening becomes far more sensory and natural.

Is sound beaming safe?

It’s accurate, safe, and can transmit music and even speech to a target without being heard by others. “Our system can be used from some distance away to beam information directly to someone’s ear,” Charles M. Wynn of MIT’s Lincoln Laboratory said in a statement.

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 do high frequency sounds do to your brain?

The hypersonic effect is a phenomenon in which sounds containing significant quantities of non-stationary high-frequency components (HFCs) above the human audible range (max. 20 kHz) activate the midbrain and diencephalon and evoke various physiological, psychological and behavioral responses.

Why can I hear dog whistles?

Humans are born being able to hear a wide range of frequencies, but we certainly can’t hear everything—especially sounds on the higher end of the frequency spectrum! Consider dog whistles, which canines can hear but we can’t. That’s because dogs’ ears have evolved to detect such high-frequency sounds.

How do I block infrasound?

Infrasound can only be blocked by a solid earplug, either custom fitted to the ear canal or sealed with jelly to generate an air-tight seal.

Why do I hear electricity in my head?

What causes tinnitus? Damage to the middle or inner ear is a common cause of tinnitus. Your middle ear picks up sound waves, and their conduction prompts your inner ear to transmit electrical impulses to your brain. Only after your brain accepts these signals and translates them into sounds are you able to hear them.

Can you play music in your head?

However, my experience is that there are many, many normal people with no psychiatric illness who have music playing in their head almost all the time or all the time. Many people have had a song stuck in their head (often called an “earworm”), but a few people have this continuously.

Is it possible to hear a sound without listening to it?

Can you listen without hearing? The answers are yes and no, respectively. Hearing is part of listening, but listening is an active process that takes time and effort. This is where the sound waves hit your eardrums, and you hear the actual sound of somebody’s voice.

Can you listen to music in your head?

Musical hallucinations are a form of auditory hallucinations, in which patients hear songs, instrumental music or tunes, even though no such music is actually playing. Most patients realize they are hallucinating, and find the music intrusive and occasionally unpleasant. There is no cure.

Can you aim sound waves?

New transmitters can aim sound waves so that only individuals in a crowd can hear them. The U.S. military sees a weapon in the making. Researchers have developed technology that can project a beam of sound so narrow that only one person can hear it.

Is audible an ultrasound?

Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from “normal” (audible) sound in its physical properties, except that humans cannot hear it. Ultrasonic devices are used to detect objects and measure distances.

Can sound be projected?

Most of the work was performed in liquids (for underwater sound use). This technology allows a beam of sound to be projected over a long distance to be heard only in a small well-defined area; for a listener outside the beam the Sound pressure decreases substantially.
