Created under the auspices of two composers, the Veme® is the first musical instrument to combine two physical phenomena : a non linear vibratory system and an aeriel coupling between a metal plate and a double membrane resonator.This technological innovation was submitted for patent in October 2014.
Mickaël Elbisser, an engineering student from the national engineering school l’Ecole nationale des Arts et MétiersParisTech worked on the project with one of his teachers, Nicolas Bonnet.Starting out from the idea of a sound which only existed in the imaginations of the two composers, they began to define a scientific approach to tracking down that sound.
The two composers described to them the type of sound they were trying to obtain as follows :
- Avoidence of overtone saturation as is the case with cymbals
- Avoidence of distinct notes such as those created by bells,
- A significant volume of low frequency sound,
- A sound which lasts,
- A powerful sound of around90 dB to 1m(the equivalent of barking dogs).,
Using these indications, the student engineer began working.
He established a scientific technical specification which would enable the realisation of the predefined objectives : the description of the sound, the aesthetic aspect of the instrument, the playing technique required, the storage of the instrument etc. Everything was taken into consideration and reviewed.
As a result, a rich sound and a beach of high frequency.
What's a sound ?
The intensity perceived depends amongst other things on the amplitude of the wave : The sound can be loud (forte) or soft (piano).
In acoustics (the science of sound), sound intensity is measured in decibels (dB).The sensitivity of the ear varies according to the frequency of the sound : the ear is less sensitive to low frequencies.0dB corresponds to the minimum intensity which the human ear can perceive., which is known as the threshold of audibility ( and isnot therefore absolute silence).From 80dB upwards the ear risks being damaged.The pain threshold is 130dB.
Timbre, determines the colour of sound..It is different for each type of sound medium.The ear is capable of distinguishing two sounds which have the same frequency fundamental and the same intensity.For example, the same note played with the same intensity by a trumpet or a violin has a different timbre.
