Low Reduced Frequency Tubes

LRFTubes a Python computer program for computing one-dimensional acoustic waves in ducts and other lumped elements. LRFTubes is used by ASCEE for modeling:

• Acoustic ducts and ventilation systems, to obtain first indications below the cut-on frequency of higher order acoustic modes, and optimize Helmholtz and quarter wave resonators and the like.
• Modeling of the insertion loss of in-ear hearing protection systems
• Modeling and designing the performance of micro-speakers for in-ear headphones (earphones)

These modeling efforts are done to reduce the amount of design trial and error procedures, effectively resulting in shorter design improvement cycles. LRFTubes contains a large amount of pre-defined models, such as for (micro)speakers, ducts with several cross section types (circular, rectangular, narrow slits), transitions, cones, the IEC 711 ear coupler, etc, which quickly enables us to model your system. Moreover, we can use the code programmatically for optimization purposes.

LRFTubes is propietary code.
