ENC Software for Noise and Vibration Calculations
The Engineering Noise Control (ENC) software offers a complete solution for various noise and vibration calculations within a simple graphical user interface. The software consists of a series of modules written to supplement and simplify all the calculations as they are presented in the book, Engineering Noise Control by D.A. Bies and Colin H. Hansen. Targeted users are mechanical engineers, noise and vibration consultants and students undertaking noise control courses, although anyone interested in noise control or who has a noise problem could benefit.

ENC comprises of 7 modules all included with the software:

  • Module 1: Fundamentals, subjective response to sound and noise criteria
  • Module 2: Sound power of sources and outdoor sound propagation
  • Module 3: Room acoustics and sound absorption
  • Module 4: Transmission loss, enclosure design, barriers (indoor and outdoor) and pipe wrappings
  • Module 5: Dissipative and reactive muffler design and duct breakout noise calculations
  • Module 6: Vibration Isolation and Damping
  • Module 7: Sound power estimation for specific source types
