The theory of traditional Chinese medicine suggests that qi is one
of the fundamental substances in human bodies. Modern scientific
research of the essence of the emitted qi has yielded some positive
results. In order to find out the relation between the emitted q7 and
infrasonic waves, to explore the mechanism of the emitted qi, to find out
how a person generates and receives the emitted qi, to provide a
quantitative physical scale for indicating the strength of the emitted qi
for experimental studies of the effect of it, we measured and analyzed
the infrasonic waves from the qi emitted by qigong masters.
The test which was done by an infrasonic testing system made in
Denmark was conducted in a noiseproof room in the Institute of Sound
and Electronics under the Ministry of Electronic Industry. The
background noise in the room was lower than 30 dB (decibel) . The
microphone was hung in the air over Laogong (P 8), the distance being 2 '
0. 5 cm with no contact.
Twenty-seven qigong masters were put to the test. Among them
twenty-four were males and three were females. Their ages ranged from
20 to 53 years old. The period of practice of qigong ranged from 4 to 32
years. While on testing, the patterns of qigong were not restricted. Non-
qigong masters were used as controls. The tests were done during the
daytime. The tested persons lay on their backs in a noiseproof room,
The experiment tested the release of the emitted qi at Laogong (P
8). Mingmen (Du 1), Baihui (Du 20). Dantian and Jianzhi. Special attention
was paid to the test of Laogong (P 8).
1. The top frequency of the infrasonic waves from the tested qigong
and non-qigong masters ranged from 8 to 12.5 Hz. In one case the
frequency reached 16 Hz. In another two it reached 6 Hz.
2. The infrasonic waves from the qigong masters ranged from 45 to
76 dB and those from the non-masters, 45-50 dB. Comparison of the
intensity of infrasonic waves during the qigong state and the non-qigong
state before and after the emission of qi showed a statistically significant
increase (P<O. 01). The increase of wave intensity of the qigong masters
compared with that of the non-qigong masters was also obviously
significant (P<O. 01 ) . The energy of the qigong masters was over 100
times higher than that of ordinary persons.
3. Different qigong patterns called for the exercisers to concentrate
their minds on different acupoints and the testing results were different.
When we tested the same qigong master at the same point, the intensity
of the infrasonic waves decreased with the increase of distance.
4. The masters who had practiced qigong for many years and often
emitted qi to treat patients had a higher intensity of infrasonic waves,
reaching over 70 dB. Those who started to practice qigong a short time
before and mainly practiced Nei Yang Gong had a lower intensity of the
infrasonic waves (lower than 60 dB).
5. While on testing, some qig±ng masters in the Valsalva state, or
non-qigong masters who simulated Valsalva, showed a higher intensity of
the infrasonic waves.
Infrasonic and ultrasonic waves are all sound waves which cannot
be detected by human ears. The frequency of infrasonic waves is below
20 Hz. Many natural phenomena and artificial actions may generate
infrasonic waves. Human bodies may act as a source or a receptor of
infrasonic waves giving rise to a biological effect. The infrasonic
information we acquired from the measurement of the emitted qi makes
it possible to study the effect of the emitted qi.
The Valsalva state in which a qigong master emits his qi is the
breath-regulating state of qigong and also the state of emitted qi in the
breath-holding exercise. Non-qigong masters who simulate the Valsalva
state also send out more intense infrasonic waves. It shows that every
person has infrasonic characteristics. A long period of practicing qigong
helps increase the radiative intensity of infrasonic waves. Entering the
Valsalva state helps in the emission of qi. The qi emitted by masters who
adopted Song Jin Gong (relaxed and quiescent pattern) had more intense
infrasonic waves (reaching 72 dB) . Thus, the mechanism of the emitted
qi released by different exercise patterns is different.
We have found by a series of tests that very able qigong masters
can keep the energy of infrasonic waves at a relatively high level (over
70 dB) . So tests on infrasonic waves can be used to screen qigong
The human body can generate and emit infrasonic waves. As far as
acoustics is concerned, the most suitable resonant frequency of human
tissues is within the range of infrasonic waves. It shows that the human
body readily receives infrasonic waves.
Infrasonic waves are a strong, effective part of the emitted qi
because of their quick, long distance transmission, strong penetration and
non-decreasing vibration. It is possible that infrasonic waves themselves
transmit the messages between the qigong masters and the subjects, or
serve as a carrier.
