最新版 Engineering Noise Control software v6.0 更新於 2023/9/1
有了 Engineering Noise Control (ENC),您就不再需要繁鎖的手工計算過程,也除去了計算錯誤的風險。幾乎所有的計算程序都可在這本書中找到 - Engineering Noise Control: Theory and Practice, Fourth Edition,它是由D.A. Bies和C.H. Hansen所驗證過的計算程序,並且封裝在一個Windows圖形用戶界面,非常易於使用,並且以表格和圖形的形式呈現結果。計算程序已經通過全面測試和檢查。所有的算法都已包含在第四版教科書裡。
這軟體最有用的功能是可做很多次的運行分析,每次運行的結果繪製在同一坐標軸上,去探索不斷變化的各種輸入參數的效果和允許的設計要實現的目標。目標用戶是機械工程師,噪音和振動顧問和噪音控制課程的學生,及對噪音管制或有噪音問題有興趣的任何人。
該軟體分為七個模塊,對應的各個部分的文字書。
A useful feature is the ability to run an analysis several times and plot the results for each run on the same axes to explore the effect of changing various input parameters and to allow a design goal to be achieved quickly. Targeted users are mechanical engineers, noise and vibration consultants and students undertaking noise control courses, although anyone insterested in noise control or who has a noise problem would benefit. The software is divided into seven modules, corresponding to various sections of the text book..
Specail Features
Common to all modules are:
- ability to use your own material properties or use the in-built ectensive data base
- multiple curves placed one at a time on the same axes to compare the effect of parameter changes
- graphical windows interface with pop-up menus and data plots
The software is divided into nine modules that roughly follow the layout of the book, Engineering Noise Control, 5th Edition, by D.A. Bies, C.H. Hansen and C.Q. Howard. Each module is associated with unique tool bar symbols (see example below) that represent different calculation procedures from different sections of the book chapter or chapters associated with the particular module. You can select the module you want from the “Options” menu at the top of the screen. Each module has a number of windows which can be selected by clicking on the appropriate symbol on the tool bar. Each window has a number of panels, each of which represents a particular calculation.
The modules and the chapters of the book that they represent are listed in the following table.
Module number | Book chapters represented |
1 | 1, 2, 3 |
2 | 4 |
3 | 5 |
4 | 6, App. D |
5 | 7 |
6 | 8 |
7 | 9 |
8 | 10 |
9 | 11 (SEAonly) |
When you select a particular module, you will find that a page will pop up that represents one particular window in that module. Each window in the module is represented by an icon in the tool bar (see an example above for the module 5 tool bar). You can tell which window you are currently in because the corresponding icon in the tool bar will appear in one of the corners of the screen and the text under the icon in the menu bar will be highlighted in red.
The symbol on the far right is the “ run” symbol on which you often need to click to make sure a new calculation occurs after you change some input parameters. The three icons to the left on the tool bar allow you to respectively, start a new calculation, open an old calculation previously stored on a file, and save the current calculation parameters for the entire page to file. If the “Save” button is greyed out, you may still save the parameters for the current page to a file by clicking on
