Research and Development
PETROF is traditionally regarded as an innovator in the production of acoustic pianos. In 1954 we set up the Department of Research and Development, which still exists today. Thanks to the methodical application of its specialists and the collaboration of other technological staff, we can boast an array of awards and patents. Our areas of interest, apart from the musical acoustics of pianos, include vibrations, signal analysis, evaluation of the attributes of wood and metal, development of special measuring techniques, and the like.
