Mostly there is a composition of high-frequency sounds, which are inaudible by themselves, and carrier sounds.

1. High frequency / Subliminal sounds

• These are sounds that a person does not hear / is not aware of, but the brain reports them.
• These sounds are solved using several methods: high-frequency resonance (phase shifts), high-frequency modulation, and the most primitive – ordinary whispering.
• Subliminal information is often communicated concurrently with some other attention-grabbing sound.

The following are the sounds that usually serve as carriers (but not always). This means that they do not sound suspicious in themselves, but it is precisely these sounds that direct attention to a certain tone, emphasize specific “lines”, etc.

2. Resonant noises and tones

• The basis can easily be ordinary noises (white, pink, brown, etc.)
• The easiest way to create a resonant sound is when one sound (in this case, noise) is duplicated and shifted, for example, by a few milliseconds. Due to interference (some frequencies are interrupted) a resonant tone is created.
• Noise can be generated using JAVASCRIPT.

3. Resonant sound, which is created by the composition of many voices together.

• The individual voices that make up the sound follow clearly defined patterns. Especially specific melodies / rhythms that are created by combining different frequencies.

4. Sequences / fragments of different voice recordings that are put together one after the other.

5. Primitive sounds that are composed, for example, of only two, three or four signals (sine, triangle, square, trapezoid, etc.)

• Only three sinusoidal signals are enough to produce intelligible speech.
• Can be generated by javascript

6. High frequency pulses / clicking.

1. Modulation of words / Whispering

• Impulses similar to the letters K, T, P are particularly prominent.
• Some variations of these impulses can be compared to whispering.

2. Impulses that they have that are supposed to disrupt and change the current activity

• If the victim is e.g. watching TV or working on the computer and keeps going for a cigarette >>> this impulse can be used to make him decide to take a break (he does not realize that thanks to that impulse it is a precisely timed event)
• In this way, the perpetrators try to influence a number of small decisions. It is something like “pushing”, “startling”, disrupting concentration.

3. Mapping space / Measuring distance using ultrasonic reflections

• To be completed

4. However, VF sounds also include sounds similar to the sound of a projectile / bullet being reflected. These sounds can also be created, for example, by clapping a corrugated sheet.

7. Simple, sinusoidal sounds.
