SELECTION SOFTWARE OF RECTANGULAR SILENCER

Required data:

1. Sound power at the appropriate frequency in front of the silencer, eg:
   

   63, Hz [dB]	125, Hz [dB]	250, Hz [dB]	500, Hz [dB]	1000, Hz [dB]	2000, Hz [dB]	4000, Hz [dB]	8000, Hz [dB]
   64	74	84	85	81	77	72	68

2. Maximum sound power in front of the silencer, e.g. 45 dB(A)
3. Air volume, e.g. 2400 m3/h
4. Desired silencer dimensions, B = 800 mm, H = 400 mm, L = 1500
5. Maximum acceptable pressure loss Pa, e.g. 60 Pa

Entering data:

1. Enter the sound power in front of the silencer in each frequency band. The weighted sound is calculated automatically, for example: 63dB: 64, 125dB: 74, 250dB: 84, 500dB: 85, 1000dB: 81, 2000dB: 77, 4000dB: 72, 8000dB: 68
2. Enter the desired sound power after the silencer, e.g.: 45dB (A).
3. Enter the air volume m3/h, for example: 2400 m3/h or 0.67 m3/s or 667 l/s.
4. Enter the desired silencer dimensions in millimeters, width B (e.g. 800 mm) and height H (e.g. 400 mm).
5. Enter the maximum possible length of the silencer in millimeters, e.g. 1500 mm. The program will provide all possible options up to 1500mm in length. If a check mark is placed, then only the specified dimension will be selected.
6. Enter the maximum acceptable pressure loss Pa, for example: 60 Pa. The program will provide all options that will not exceed this limit.
7. After expanding the menu, enter the project data, which will be displayed in the report
8. Click the "Calculate" button and select the most appropriate silencer from the list.
9. Clicking on the link of the selected silencer opens a table where you can check the obtained numbers, and clicking on "Send PDF" generates a report on the technical characteristics of a specific silencer. All you have to do is print it out or save it on your computer.
