On the acoustic vibration effect of the brain and its benefits to our lives

If we consider the skull as concrete walls, the brain is like a concert hall; when we speak, vibrations propagate and reverberate within it. Research on brain vibrations conducted by the Architectural Acoustics Laboratory at Tsinghua University has scientifically confirmed their existence.

Functional magnetic resonance imaging (fMRI) scans can clearly show hundreds of millions of nerve fibers in the brain. Through the network of connections between nerves, the brain produces higher-level activities such as sensation, judgment, decision-making, and thinking. The nutrition and metabolism of nerves mainly depend on the flow and circulation of cerebrospinal fluid in the interstitial spaces .

Brain vibration is related to the resonance of the three cavities (oral cavity, nasal cavity, and cranial cavity), and a trained way of speaking can generate a greater amount of vibration .

Reading aloud is one of the methods that can produce a brain vibration effect .

The Architectural Acoustics Laboratory of Tsinghua University, in collaboration with Beijing Changping No. 2 High School, conducted an experiment. The results showed that students' grades improved significantly after reading aloud, with an overall score increase of 3.3%, a 4.6% increase in scores for subjects requiring reading aloud, and a 2.2% increase in scores for subjects requiring reading aloud.

Furthermore, an experimental study in a middle school in Nanyang, Henan Province, on the relationship between vocal vibration and academic performance (44 students/semester) also found a positive correlation between vocal vibration and academic performance . An increase of 10,000 vibrations per day was associated with an improvement of approximately 7.5 points in academic performance, with a correlation coefficient of about 30%.

The brain's acoustic vibration effect can not only promote students' intelligence and improve their grades , but also has an auxiliary effect in preventing cerebral infarction.

Intracranial vibration causes blood vessels to vibrate; the reciprocating motion of this vibration helps clear cerebral blood vessels and aids in preventing infarction . The principle is similar to tapping water pipes to prevent rust, using ultrasound to clean eyeglasses, or using ultrasound to break up stones.

Tsinghua University, together with Beijing Xuanwu Hospital and Tsinghua School of Medicine, conducted a 6-month follow-up experiment. Thirty participants (aged 40-75) recited a customized mnemonic for 30 minutes daily (approximately 100,000 tremors). MRI scans were performed to compare changes in cerebral blood vessels and lacunar infarcts (small infarcts) before and after the 6-month period.

Experiments revealed that all lacunar infarcts showed no degenerative changes .

The acoustic vibration effect has a positive impact on brain health , and both children and adults should consciously engage in related exercises to enjoy its benefits .
