Neuro - Sound effects
Neuro sound effects are special acoustic signals that specifically synchronize, harmonize or activate both hemispheres of the brain. This stimulates the ability to concentrate and think as well as the state of relaxation.
Bilateral hemispheric stimulation
If both hemispheres of the brain are stimulated alternately, they connect and network with each other. This effect can also be achieved with a special type of music in which both hemispheres of the brain are synchronized. Music with bilateral hemisphere stimulation is structured in such a way that the beat goes from left to right, i.e. alternates. Parts of the music change sides with each beat and thus the ear. The cerebral hemispheres are thus activated alternately. The brain becomes better connected, existing neuronal networks are stimulated and expanded or restructured. Music of this kind has a harmonizing and calming effect on body and mind. It has a soothing and relaxing effect on the state of arousal of the entire nervous system. This effect occurs automatically after just a few minutes of listening. Due to the special activation of the brain, the music can also be used when you are awake. It directly influences the feeling of well-being at the level of thought and behavior and increases the ability to concentrate - ideal for creative processes.

Random brain stimulation or pink noise
White noise is the so-called background noise of the universe. It is a noise with a constant power density spectrum, it is continuously noisy across the entire frequency spectrum. This can be observed in older televisions when there is reception interference. In psychoacoustics, white noise is used to combat noise and in the field of Tinniuts retraining therapy. Noise and other disturbing sounds are subjectively perceived as less loud and disturbing if they are overlaid with white noise. However, it is still perceived as a noise with a strong emphasis on high frequencies and is therefore perceived as unpleasant. Pink noise, on the other hand, sounds much more pleasant to the ear. In principle, it corresponds to white noise, which has been optimized for the human ear in various frequency ranges. It is ideal for stimulating the brain in the audible frequency spectrum in random succession. If the noise now changes slowly from left to right using panorama control, a three-dimensional perception of the noise perception is created in the head. This stimulates and synchronizes the brain very finely in the full frequency range. A general feeling of well-being is created.
Binaural beats are perceptible sounds that are produced directly in the brain when two slightly different frequencies are fed separately to the ears via headphones. From a physical point of view, binaural beats are a form of beat. The effect can be understood using a practical example: if you hear a frequency of 100 Hz in the left ear and a frequency of 108 Hz in the right ear, a pulsating, linearly oscillating sound, also known as a beat, with a frequency of 8 Hz is produced. This corresponds to the difference between the two frequencies. A brain oscillation of 8 Hz is in the lower range of the alpha state. The brain is led into a very relaxed state on the verge of falling asleep. With special frequencies, the latter can be generated in a targeted manner. neurotunes places pleasant relaxation music over this vibration. This provides a pleasant listening experience and the effect of the binaural beats can unfold better in the brain. Binaural beats therefore have a subtle influence on the brain. They stimulate the brain waves in a selected area. In this way, they promote relaxation, sleep, attention or the ability to concentrate.

Head Related Transfer Function HRTF
This neuro sound effect simulates completely natural three-dimensional hearing. The sound source comes in all possible combinations either from the front or back, from above or below and from the left or right. Several parameters are relevant when locating the sound source: the time-delayed arrival of the sound in the right or left ear and the unevenly perceived volume (level). In addition, there are sound colorations of the sound that are caused by the individual characteristics of our auricles, head and body. A sound behind me sounds different to a sound in front of me. The auricles reduce the high frequencies coming from behind. Additional reflections and phase differences are created by the ears, head and body. This allows the brain to calculate and recognize what is happening behind, above and below us from the incoming sound waves. The auditory experience is fundamentally very individual and has a significant influence on how we find our way in nature.
In the headphones, it is quite easy to differentiate between right and left. The simulation of top and bottom and front and back is somewhat more difficult due to different reverb levels and a frequency filter. With the "Head Related Transfer Function" (HRTF), all these relevant data of the differences in runtime, level, phase and frequencies are changed accordingly by a specially developed algorithm. This algorithm was created using average data from the human body.
This creates a listening experience that is perceived as very natural. When listening to the sounds of nature, you actually have the feeling of being in the middle of the action. The spatial illusion is enhanced by closing your eyes.
The HRTF neuro-sound effect will be explained in more detail using a practical example:
All instruments are arranged around the head. The pad sound is far behind the head, the percussion is in front of the body in a semi-circle in the first row, the piano and acoustic guitar are placed about 3 meters away from the left and right ear respectively. A relaxing forest atmosphere is created a few meters above the head, the bass plays below the body. Only the voice, as the only mono signal without HRTF technology, seems to be in the middle of the head. A production with HRTF technology therefore sounds very spatial. In comparison, a standard stereo mix sounds correspondingly more boring.
- Extraordinarily impressive listening experience
- Listening via headphones analogous to natural perception
- Stimulation of different brain regions
- Relaxation in authentically simulated nature
- Let go of everyday life and relax more easily
If you listen to music at a tempo that roughly corresponds to your resting heart rate (approx. 60 bpm), your heartbeat adapts to the rhythm of the music. After approx. 10 minutes, the heart beats in sync with the music.
With beat-pulse regulation, the tempo of the music is slowly reduced from 60 bpm to 52 bpm after a short adaptation phase. This means that the pulse rate is also reduced to 52 bpm. As a result, breathing becomes calmer, the muscles relax and the brain frequencies are reduced.
