Sound and Vibration Analysis Working Group

A research data announcement conference “Singing Ring Vibration and Resonance Analysis Vol.2” has taken place at the Tokyo Metropolitan Industrial Technology Research Institute (HQ) on the 8th of December 2017 by Society of Damping Technology, Vibration and Sound Analysis Working Group. The announcement was done by Associate Professor Yoshio Kurosawa from Faculty of science and technology

Department of Mechanical and Precision System at Teikyo University.

Three sounds create impossibly beautiful integer multiple

In 2017, the research has taken place to find out more about the reason how and why the Singing Ring creates the long, wavering, and complex sounds.

The research group measured the individual frequencies and compared the three different sounds that the Singing Ring make (the sound of 4, 6, and 8). As a result, they found out that the three sounds configure integer multiple. This is very outstanding and it’s a beautiful integer multiple that cannot be made by coincidence. This means that these three sounds’ wavering frequency don’t clash with one another and it can sustain the long resonance in a harmony.

 

They also used a computer simulation system called “FEM” to identify whether the forms of the bowls are holding the secrets to why the three sounds of Singing Ring create beautiful integer multiple.

In this research, they used three different forms that has the same diameter of Singing Ring Daichi, and three different forms of elliptical, a combination of columnar and hemisphere, and columnar shape which are made to create the three sounds and tested to see what kind of multiples the three sounds configure. As a result, any of those forms “did not create integer multiple. This result shows that the three sounds creating the harmonious frequencies was not just a coincidence, but “the result of many elements combined such as the unique form of the Singing Ring, the balance of the thickness of the bowl material and other elements” and it concluded that “in order to create the same sound effect, the ”design factor is too complicated and unable to create it just by calculation”.

 

There was another experiment result announcement. They compared the Singing Ring before and after the coating to figure out whether the coating affected the sound or not. The result concluded that “the effect to the sound by urushi coating wasn’t detected.” Through this experiment, the result scientifically proves the effectiveness of applying the urushi coating for rust and degradation prevention.

 

We identified the individual frequency of the sound emitted.

We have simulated the sound of 4, 6, and 8 creating the beautiful frequency and analysed them. The result shows that each frequency creates integer multiple and creates long resonance with wavering sound of low frequency.

Scientific analysis of the harmonic resonance

Also, they also used FEM for measurement to prove the sound resonance phenomenon (when you strike one bowl, the other bowl nearby starts ringing) and they have concluded that “it caused the sound resonance phenomenon”.

When you strike one Singing Ring, another Singing Ring will start ringing without being struck.

Red: Singing Ring that’s being struck.

Blue: Singing Ring that resonated to the first bowl.

 
Relaxation effect of Singing Ring resonance for the elderly
Professor Yasue Mitsukura, Keio University

In June 2018, there was an experiment on the elderly taking brainwaves data using KANSEI Analyzer. This is following a 2017 experiment run on 110 people between the ages of 20 to 60. This experiment was held on elderly people above 60 to find out the relaxing effects of the sound of Singing Ring.

Each examinee’s change in average value 60 seconds before the Singing Ring session and 60 seconds after the session.(Using the data of the 23 examinees)

Stress Value Decreased and Calmness Value Increased in Elderly's Session Too

After analysing the result of the experiment aimed at 23 elderly people, when we look at the change in average value, 83% of the 23 people’s (19 people) stress had decreased and 78% of the people’s calmness had increased.

From the research we conducted among 110 people in 2017, we confirmed the stress decrease in 81% of the people, and calmness increase in 79% of the people. Taking a look at the experiment results from this time, we can see the same tendency of the stress decrease and calmness increase for the elderly people.

From these results, we can say that elderly people also gain relaxation and calmness from the Singing Ring session.

 
“Emotion Analyzer” proves that it calms the mind.
Associate Professor Yasue Mitsukura, Keio University

Keio University Associate Professor Mitsukura who developed “Emotion Analyzer,” the world’s first device which enabled to measure the person’s emotion real time, in collaboration with Dentsu Science Jam after 15 years of experiments, measured the people’s brainwaves data after they listened to the sound of Singing Ring.

She successfully removed the noise caused by blinking and swallowing, and accurately measured and numerized the emotions such as “Like” “Interested” “Focus” “Stress” “Calmness”.

We experimented on 110 examinees including many Keio University students at Shinjuku Kagurazaka Salon, we learned that the stress value has decreased by 24.1% in average, and the calmness value has increased by 72.3% in average after the session. The latest science technology has proved that the sound of Singing Ring makes people calm and relaxed.

Singing Ring session was given to 110 examinees with the bowls being placed above the head, side of the ears, on the body, and between the legs.

Cases of the stress value decreased (89/110 people, average 24.1% down)

Cases of the calmness value increased (87/110 people, average 72.3% up)

 
Characteristics of the 3 bowl-shaped instruments
Society of Damping Technology (SDT)

Singing Ring, an instrument that creates long wavering multiple resonances.

The vibration research group, the Society of Damping Technology (SDT) established a working group from March 2016 and has been researching and analyzing the unique resonance of Singing Ring.

I’d like to announce the research data from 2016. These are the findings from the analysis of how the sound and vibration of Singing Ring differ to the Tibetan Bowl and Crystal Bowl in comparison.

 

Tibetan Bowl: A deep sound of multiple tones and the wavering* is short. The sound diminishes quickly.

 

Crystal Bowl: A clear single tone and the wavering is long. Suitable for playing a melody.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Singing Ring: In comparison, Singing Ring creates multiple tones and the wavering is long. We can say that the “rich resonance lasts long”. From this research data, we can say that Singing Ring has a completely different musical characteristic compared to other musical instruments.

 

The research group concluded that the reason for the characteristic sound is the result of the precise shaping and the ratio of the special alloy.

 

*The sound volume gets large and small periodically and sounds like it’s wavering.

 
Measured the frequencies of the sound of
the Singing Ring using Voice Analyzer

We measured the frequencies of the sound of the Singing Ring using Voice Analyzer.

What's worthy of special mention here is that it distributes all the frequency equally. The Ministry of Education and Kyoto University co-researched and they have announced that the music from high to low frequency increases the blood flow of the hypothalamus and brainstem at the 4th International Conference on Neurology and Therapeutics. This suggests that the sound of Singing Ring that contains a wide range of frequencies could bring numerous potential effects such as possibly increasing the blood flow of the hypothalamus and brainstem.

 
EAV(Electro Acupuncture according to VoⅡ)
Dr. Akihiro Shikano

EAV (Electro Acupuncture according to Voll) is measuring equipment invented based on a theory of German doctor of medicine, Fritz Werner. By sending an imperceptible electrical current through a path and measuring current resistance levels, the equipment detects what part of the energy is disturbed. More than 20,000 units of EAV have been used around Germany and they are used actively in the medical field.

We held an experiment using EAV to measure the effects of Singing Ring.

We asked the examinees to cover their head with Singing Ring, listen to the sound for 3 minutes, and then we measured the EAV value of before and after.

A healthy state is 50 to 65. If it’s higher than 65, there is a tendency of hyperfunction. If the measurement is lower than 50, there is a tendency of hypofunction.

All 21 people who had the EAV examination had a measurement close to 50 after listening to Singing Ring.This means that the use of Singing Ring helps correcting the meridians balance and energy balance and overall being in a healthier state. This is a surprising result.

We confirmed that it was effective in all cases. We will keep on studying more cases in the future to prove the effectiveness of the Singing Ring.

 
A quantitative evaluation on stress levels using the biomarker
Dr. Yuko Matsushima, Yamanashi Prefectural University

A quantitative evaluation on stress levels using the biomarker. The level of one of the adrenocortical hormones called cortisol, which is released due to stress, was measured from salivary amylase.

More severely stressed cases showed larger effects on the decrease of cortisol levels, after listening to Singing Ring(R).

The result suggested the possibility of Singing Ring(R) affecting the parasympathetic nervous system.

 
Singing Ring’s sound and the brain waves
Dr. Kimiko Kawano, Nippon Medical School

” Listening to Singing Ring(R) while lying on the stomach seems to relax the person the most and it shows how alpha waves are gradually growing larger. It is significantly shown also that alpha waves move from the vertex towards the front of the brain. This occurrence is similar to what happens in meditation. Being in the resonating sound space, the cerebral neocortex, which is normally active, is restrained: therefore, a state of mind similar to that found during meditation is created.”
