WinFlag ver. Educational Description

WinFLAGAcoustic Performance Estimation SoftwareNew: WinFlag 2.1 is now released. We have also released the software WinRT60. Do you need to estimate the acoustic performance of constructions combining different material layers such as porous materials (e.g. mineral wool), solid and perforated plates (slotted, with circular holes, microperforated)? Download and evaluate WinFlag 15 days for free from here. From the same link you may also download and evaluate our low price alternative WinFlag ver. 1.0. For pricing and for purchasing WinFLAG, click here. If you have questions about WinFlag, please use the WinFlag/WinRT60 forum. User Reviews"Personally, I think it is a great program!" - Walter Lauriks, KU-Leuven, Belgium ?I have to say I love this program. It is a matter of seconds to design an absorber panel for a specific frequency, and adjust its Q. Compared to similar software it is more straightforward, quicker, and looks overall more professional.? - Thalis Menexelis, Athen, Greece "The manual and program looks very intuitive and good with references for the models. I think this program is an useful tool for acoustics consultants and even producers of absorbers." - Anders Buen, Brekke & Strand Akustikk AS, Norway WinFLAG Overview WinFLAG does the job calculating absorption coefficient, impedance and sound reduction index for constructions combining different material layers such as porous materials (e.g. mineral wool), solid and perforated plates (slotted, with circular holes, microperforated). WinFLAG version 2.1 also calculates the attenuation of noise in ducts, e.g. air-conditioning ducts, lined with the chosen layers. Calculations may be performed at single frequencies or as mean values in one-third-octave bands, for free and diffuse field sound incidence. For exported data (MS-Excel or ASCII) values in octave-bands are presented. One may estimate the absorption coefficient measured in a standard reverberation room according to ISO 354. These absorption coefficients may be directly exported to the program WinRT60 that calculates the reverberation time in rooms. WinFLAG uses for calculations a transfer matrix method with two physical variables; sound pressure and particle velocity. This implies that porous materials are treated as equivalent fluids, which will not fully represent certain foam materials. The program will, however, give a proper model in a vast number of cases and certainly be useful both for acoustic consultants and for students in acoustics as well. For details please see the WinFLAG manual. · Calculates the absorption coefficient for 14 different types of layers, including 4 different models of porous materials. The absorption coefficient may be calculated, with some exceptions, for any combination or any number of these layers limited to a total of 20 layers. A 15th type of layer, the infinitely hard wall, may be included in the case of absorbers placed against a hard wall in a room. · Absorption coefficients obtained in a standard reverberation room (the commonly used product data after ISO 354) may be estimated, as well as the weighted sound absorption coefficient aW according to ISO 11654. · The sound reduction index in dB (sound transmission loss) is simultaneously calculated for all combinations not including the infinitely hard wall. The weighted sound reduction index Rw according to ISO 717 Part 1 is also calculated when applying a diffuse field option and calculating results in one-third-octave band. · The acoustic impedance is also simultaneously calculated in all cases when an angle of sound incidence is specified. · All the data mentioned above may be calculated for a given angle of incidence or in a diffuse field. · Calculations are performed at single frequencies or as mean values in one-third-octave bands. There is also an option for exporting calculated results as mean values in octave bands. · WinRT60 is an accompanying program calculating the reverberation time in rooms, and absorption coefficient data are transferred directly from WinFLAG via the Clipboard. · As an add-on to the program the attenuation of noise in ducts, e.g. air-conditioning ducts, lined with the chosen layer configuration may be calculated. · A report window in Rich Text Format (.rtf file) is implemented where specifications, tables of results and diagrams may easily be imported. · Results, together with specifications for the combination of layers, may be exported to a plain text file (ASCII), alternatively to a Microsoft Excel file. · A chosen combination of layers, a configuration, may be saved to a file and later imported for additional calculations. The same applies to single layers, which enables the user to build up a library of material layers. New features in WinFLAG version 2.1 (upgrade from version 2.0) Two new types of layers have been added. In relatively thick perforated panels, 9?10 mm or more, both calculations and measurements show that using conically shaped apertures, as opposed to normal holes or slots, may greatly enhance the absorption capabilities of resonator panels. The figure below shows measured and calculated reverberation room data. In addition to the normal hole-perforated panels one may now design resonator absorbers that have conical apertures instead of the cylindrical ones. In case of slotted (slatted) panels, the beams (slats) have a trapezoidal form. · When exporting calculated results, either to a plain text or Microsoft Excel file, the data will be preceded by a list specifying the properties of the layer configuration. Furthermore, calculated results in octave bands may be added to the results calculated in one-third octave bands. · Results may also be exported, via the Clipboard to the program WinRT60 that calculates reverberation time in rooms. · As the menu Add layer had became quite long, submenus have been introduced for porous materials and perforated or slotted panels. The specific layer is no longer automatically added to the end of the list, but may be directed by the user. · Deleting a layer in the list, using the Delete button, has been replaced with a Cut and Paste button. · A submenu Properties of materials has been added to the Help menu, calling up a table of material data.
