ADNR (free)

A practical and easy-to-use software for structural acoustics and vibration of complex plate-like structures. Excellent tool for preliminary design of noise control solutions and for education.  Useful to pre-design damped panel-like structures in the car, aerospace, marine, train and other industries. ADNR uses a variational approach that allows quick and accurate calculations of the effects of structural complexities on the vibro-acoustics of multi-layered plate-like structures.
