Recently, the research activity has been focused on cooperation with universities, research centres in our country and abroad. The results gained from academic research is then applied and used in practise. The research is concentrated on the question of creating numerical models of individual parts of the piano having influence on its acoustic features. For that purpose, measuring methods are developed in order to allow for the obtaining input data for numerical models and to allow for assessing the validity of such models. At the same time, the developed measuring methods serve directly to objective assessment of the quality of our production.
Empirical knowledge obtained by cooperation of manufacturers and musicians have been more and more significantly completed with music acoustics and technical physics recently. The development of these branches actively solves the related improvement of the sound of the instruments.
Research of the influences of changes of the materials and technologies used is possible and very necessary, both from the point of view of long-term stability, and from the point of view of acoustic qualities of all instruments.
The possibilities of the research are almost inexhaustable thanks to the experience passed on from generation to generation, maturity, detached view with certainty and at the same time with respect, devotion and humility. With regard to the wish to know the not known and to discover new cooperation between the science and the building of music instruments, the creative work is based on systematic activity extending the accuracy of understanding, which leads to the use of the obtained knowledge and creation of hypotheses in new or considerably improved technologies introduced into the practical production of musical instruments. Petrof wants to help the client to recognize high-quality goods. PETROF brand is based on tradition - tradition of our instruments made by qualified people with long-year experience.
