Most audiophiles   still  regard Shun Mook as black magic  or perhaps psycho-acoustics and imagination.  The belief of traditional science in what is known is known and must be proven by measurement and tests.. Yet there are so many things that science still do not know and cannot explain.

Shun Mook is not black magic but very simple physics.  Sympathetic resonance is the main principal behind it.  As in high school you have experimented with tuning forks.  Strike one fork of one frequency and bring it next to a same stationary fork, this one will start to react without even touching it.

Sound as we know it is movement of air caused by the pulsation or vibration of some material. The quality of this movement is the result of resonance of the material providing this vibration.  Different material gives out a difference resonance character.  For example steel, glass, marble, wood all has their resonance signature. 

Musical instruments produce sound from vibration of its material - to give us different pitches and frequencies of sound.                                                      

The inherent cellular resonance produces the type of sound produced.   Strings - from a box of wood of various sizes and shape.  Woodwind - from sections of tubes with holes in varies positions.  Brass - by forcing of air through a metal tube..  Precussions - by beating of skin on frames of wood etc etc.
All these are the result of resonance of the material at the cellular level producing sound as we know it.

Shun Mook is made from mpingo ebony wood. Mpingo - in Africa means tree that sings.   Ebony wood has the most musical properties in its resonance characteristics or else the string instruments will not be using them as fingerboards and woodwinds will not use it for its body. 

Looking at a section of the wood it consists of thousands of tubes, or its cellular structure is like a micro-sized pipe organ.  When energy makes contact with this material it creates multiple vibrations of the most complexity within its body.  Vibrating strings when stretched on this wood gives out a complex but musical

tone to the human ear.  On the other hand a plastic fingerboard on a string instrument will create another pattern, but a pattern of a not so musical sound.

The Shun Mook disc is like a musical instrument, receiving sound energy from the speaker and then become excited, resonates and releases a sympathetic resonance of a musical character to its surrounding.   Our invention is making a disc that will resonate at an enhanced rate with the effect of masking the non-musical frequencies and harmonics while amplifying the natural musical tone spectrum.  It is acting like a tiny amplifier in a sense that it will energize, absorb, resonate and radiate to its surroundings.

Most tuning devices aims to cancel or absorb resonance, these are actually resonance from non-musical materials, like steel, brass, lead, glass, marble, granite, plastic, rubber, MDF wood, etc.  The resonance from these material are damaging to sound produced by the loudspeaker and therefore has to be controlled.

Energy cannot be destroyed, that is a given in physics, that is as far as we know. Most devices attempts to damp, absorb or isolate the vibrations from these material but cannot cure the fundemantle problem.  You think the rubber feet at the base of the amplifier dampens the vibration, yet it only stores the energy for the moment and delay a release back to the system with the rubber resonance mixed in as a feed back.  That’s why air bags and pressurized air suspensions does not work well due to the time delay feed back of the negative energy (non-musical).  Heavy composite of steel, lead and plastic also just delays the bad resonance and smear up the signal in micro seconds delay.

With Shun Mook we channel away the bad sounding resonance energy because it cannot be destroyed.  Just as you cannot stop a flood with a wall you have to dig a cannel to divert it.   In this case we use our diamond tipped resonators.   The diamond crystal being the hardest material on Earth can release the vibration instantly while the ebony wood body acts like a reservoir for the musical energy to excite the resonance energy in its body. Hence this musical energy is feed back into the system while the diamond acts like a mechanical diode – pass the unwanted vibration out one way.

Of course we have some trade secrets as how to enhance this wood and determine the maximum direction of the flow resonance energy in a piece of ebony.  Anyone can make an ebony disc with real ebony, in fact 20 years ago when our disc first hit the market in Hong Kong, within a few hours it was dissect by some copy cat who did try and make some disc of their own but of course was never successful.  All they have are some duds - not alive.

A simple test by yourself or your clients is to hold the disc with the Chinese logo up or down in one’s palm and feel the weight. Flip the disc over and weigh it the other way, you will feel the logo side down is heavier then the other way.  Why?
This is crazy, nothing is added, same disc.  There is an energy flowing through the disc to your palm that is enhanced within the ebony.  The energy from your palm is the aura of your body that is reacting to the disc energy. 

For a male human the aura flows out of your left hand and flow towards your right hand, while for a female its the other way around.  The disc is not as simple as it looks and there is a complex process involved in the making of it.

We also make other tuning devices such as the diamond tipped resonators, LP record clamp, dowsing pendulums, vacuum tube resonators etc.  All of them can give you real improvement in sound in your hi fi system.

Last five years we have been involved in applying our technique in concert hall design and tuning. To this day three major concert halls has applied our Shun Mook devices to enhance the acoustics in South Korea.

I hope this explains a little bit about how and why Shun Mook works.  Most human have very acute senses and therefore can pickup the changes sound of their Hi Fi system. The human senses are far more superior then any sound measuring instruments.

You can hear the result of Shun Mook by trying it in your system.



Shun Mook Mpingo™ Discs Acoustic Test

The objective of this paper is to measure the acoustic characteristics with and without Shun Mook Mpingo Discs (SMD as follow) under the same HiFi setting.

3 SMDs were put in the domestic environment under Shun Mook Instructions and the Sound Pressure Level (SPL as below), Phase and harmonics were measured. The 2-D Waterfall diagram was adopted to determine the output
reverberate time (RT60).

Measurable and repeatable result can be made by acoustic equipment. 3 SMD enhance the harmonics effect in the audio band. Over the past 30-year practical experience from the Shun Mook founders, Shun Mook Mpingo discs were
created and applications of them were developed in order to reinforce the analog sound by special structure of Ebony and tweaking the SMD.

There are series of instructions of application of SMD. However, instruction 8, Simplified Spatial Control was selected to test the SMD effect on acoustics. The placement of SMD in the HiFi setting was recommended by the Shun Mook

The results of measurement show the enhancement on RT 60 and harmonic reinforcement.
