CONVERSATIONAL CHAT INFORMATIVE BOOK Ghost frequencies and infrasound are two topics that have been of interest to paranormal investigators for many years. Ghost frequencies are said to be the sounds that ghosts make, while infrasound is a type of low-frequency sound that is below the range of human hearing. There is no scientific evidence to support the existence of ghost frequencies, but there is some evidence to suggest that infrasound can have a psychological effect on humans. For example, infrasound has been shown to cause anxiety, fear, and even hallucinations. In recent years, there has been some new research on the topic of ghost frequencies and infrasound. For example, a study published in the journal "Frontiers in Psychology" in 2021 found that infrasound can cause people to feel uneasy and anxious. The study also found that infrasound can make people more likely to believe in ghosts. Another study, published in the journal "PLOS One" in 2022, found that infrasound can cause people to experience hallucinations. The study found that infrasound can cause people to see and hear things that are not there. While these studies do not prove the existence of ghosts, they do suggest that infrasound can have a significant impact on human psychology. This suggests that infrasound may play a role in some of the paranormal experiences that people report. It is important to note that more research is needed to fully understand the impact of infrasound on humans. It is also important to note that infrasound is not the only explanation for paranormal experiences. There are many other possible explanations, such as psychological factors, environmental factors, and even fraud. Overall, the latest developments in the research on ghost frequencies and infrasound are intriguing. However, more research is needed to fully understand the impact of infrasound on humans and to determine whether it plays a role in paranormal experiences.
