Accoustics & Vibration Control Development and Software
|
Active noise cancellation using anti-phase sound waves to cancel unwanted noise has been around for many years but it's application is now rapidly expanding due to the capability of modern digital electronics and the ability to achieve performance that cannot be achieved with traditional passive approaches. Cancelling noise and vibration has moved on from simple feed-forward or feed-back systems targeting isolated, specific areas, to composite systems with more complex algorithms targeting larger areas and multiple sources.
Tactiq takes a system modelling approach to ensure that the physical systems, electronics and algorithms work together allowing different system architectures to be evaluated without costly prototype development. This approach coupled to our extensive algorithm development, acoustic signal processing and active noise cancellation and vibration control systems experience, enables predictable, lower risk development of demanding acoustic and vibration control systems.
Active Noise Control
Active control systems are often complimentary to traditional passive approaches with the passive systems controlling high frequencies effectively and the active control systems handling lower frequencies. The nature of the physical system and type of noise determine the choice of system architecture. Options for these architectures are listed below but combinations are also used for more complex applications:
A number of different algorithms can be employed such as Filtered XLMS/ULMS, RLS or Lyapunov tuned LMS, and determination of these and the best architecture are driven by answering the following basic questions:
Tactiq's total system approach includes modelling the physical system and control solution at the concept design stage to identify the technical challenges early and predict the likely performance. This approach ensures the final product can be realised, has the performance expected and gives a platform for further features.
