ENC is software that works like a tool box for sound and vibration calculations according to the book Engineering Noise Control developed by Causal Systems in Australia.
ENC is comprehensive software divided into nine modules, corresponding to various sections of the text book Engineering Noise Control by Prof Colin Hansen and David A Bies (sixth edition).
- Fundamentals and criteria
- Sound source calculation
- Sound propagation (incl. meteorological, barrier and ground effects)
- Room acoustics and sound absorption
- Transmission loss, enclosure design, barriers (indoor and outdoor) and pipe wrappings
- Dissipative and reactive muffler design and duct breakout noise calculations
- Vibration isolation and damping
- Sound power estimates for specific source types
- Statistical energy analysis (SEA)
ENC has been developed by Prof Colin Hansen, University of Adelaide in Australia, the author of many books about noise and vibration control, active noise cancellation etc. (The picture shows the sixth edition)
The nine modules are presented in the brochure that you can download below. ENC_brochure_vibraphon
ENC is unlocked with a hardware USB-dongle. The software can be installed on unlimited number of computers, but the dongle has to be moved. There is also a network version available, where ENC and the dongle is installed on one of the computers on the network, normally the server. ENC can be operated from all computers connected to the network up to a limited number of users.
