Decoding the information contained in the TFS considerably supports the pitch perception process. Propagating in the nerve fibres of the auditory nerve, the action potentials encode temporal fine structure (TFS) information of the acoustic signal 15, 16. This phenomenon involves the neuron generating action potentials at well-defined phases of a periodic acoustic signal 13, 14. The phase-locking effect is mainly responsible for the mechanism of binaural beats. The phenomenon of binaural beats occurs when tones with slightly different frequencies are presented separately to the right and left ear. There is thus a question of whether home-use binaural beats brain stimulation is safe, as well as whether it is effective at all 12. ![]() Such conditions are completely different from those known from scientific research into binaural beats when exposure to binaural beats is very short (from several seconds to several minutes) and accidental (most often linked to one visit to the laboratory) 9, 10, 11. They suggest that these activities should be carried out every day while listening to accurately selected binaural beats, which is why the recordings available on the Internet are very long (from several dozen minutes to a dozen hours). On the web, there are numerous guidelines on how to use them at home in order to support the process of learning (e.g., when preparing for an exam), solve problems (e.g., when working from home) or carry out other cognitive tasks. On one of the most popular online video-sharing websites alone, there is therefore a huge number of binaural beats recordings labelled as “genius brain frequency” or “reach super focus”. In order to stimulate, a headset connected to a smartphone or computer will suffice. What is more, an audio file for brain stimulation can be placed on the Internet, e.g., on audio/video sharing platforms 8. In this case, a simple computer and a basic program for sound processing are sufficient to build a modulator. ![]() An incredibly widespread brain hacking tool is auditory brain stimulation, in particular binaural beats brain stimulation 7. The movement of neurohackers or brain hackers 4 has also been quickly developing recently on the Internet, they show how to build tools for brain stimulation and how to use such forms of do-it-yourself (DIY) brain stimulation 5, 6. tDCS devices aimed at home use in order to-according to their producers-improve focus, attention, memory, and productivity can also be found in online markets at a very low price. Business dedicated to all sorts of home-use neuromodulators is thriving, a sign of which is the growing number of online brain shops that offer devices for home-use improvement of brain functioning 3. An example of the latter are transcranial direct current stimulation (tDCS) devices 2. They include big and expensive devices that are only used in scientific or therapeutic laboratories, for example the equipment for transcranial magnetic stimulation (TMS), as well as small and relatively inexpensive ones that can be used at home. Noninvasive brain stimulation (NIBS) techniques are currently very popular, both as tools for studying brain functions and strategies for supporting its functioning 1. Thus, home-use binaural beats brain stimulation brings reverse effects to those assumed: instead of supporting the effectiveness of cognitive activities, it may weaken them. We found that listening to binaural beats was not neutral, as it dramatically deteriorated the score irrespective of the condition. The first one was informed that they would listen to sounds that improve the brain's work, the second that neutral sounds, and the third that some sounds the nature of which was not defined. The binaural beats group was divided into three subgroups. ![]() Some took the second part listening to binaural beats, while others took it in silence or listening to other sounds. Here we test 1000 individuals at their homes as they perform a two-part fluid intelligence test. Thus, without belief in it, it may bring no benefits. However, such home-use brain stimulation may be neutral to cognitive processes, and any intellectual improvement may be only a placebo effect. Binaural beats brain stimulation is a popular strategy for supporting home-use cognitive tasks.
