MYSPHERE 3 has been developed by LB-acoustics Messgeräte GmbH applying their core competences in sound and vibration measurement technology.
Meeting the requirements of the audiophile community all measurements are carried out according to the latest technical standards. This includes simple sound measurement as well as mechanical vibrations and psychoacoustic tests. But the final examination is made by the human ears of our test persons, which significantly influences the whole design concept.
