Sound and vibrations fundamentals for electrical engineers

50,00 €


This part of the training covers the fundamentals of acoustic noise and vibrations for electrical engineers who are not familiar with mechanical / vibroacoustic engineering. Key notions such as vibrations, structural modes and resonance, sound pressure / power, A-weighting and sound quality are covered. The link with electrical machines is regularly done during the course.
