This type of correction is about the background noise. | This type of correction is about the background noise. | ||
There are three methods to define the K1 correction factor (Manual, File or Measurement). | There are three methods to define the K1 correction factor (Manual, File or Measurement). | ||
======K1 manual determination====== | |||
The manual method allows you to enter the K1 value for each frequency between <nowiki>[</nowiki>20 Hz; 20 KHz<nowiki>]</nowiki> or <nowiki>[</nowiki>20 Hz; 10 KHz<nowiki>]</nowiki> according to the frequency range you have selected. | |||
The Standard requirements are for user information (given by the selected standard). | |||
[[Image:Sp_corrections_02.png|framed|none]] | |||
Double click on the '''K1 values''' setting, the following window is displayed: | |||
| |||

[[Image:Sp_corrections_01.png]] | |||
'''K1 file determination''' | |||
The file method allows you to load the K1 value from a saved setup. | |||
The Standard requirements are for user information (given by the selected standard). | |||
| |||
[[Image:Sp_corrections_04.png|framed|none]] | |||
Double click on the '''Correction mode''' setting, the following window is displayed: | |||
[[Image:Sp_corrections_05.png|framed|none]] | |||
'''Average correction mode:''' source average in relation to the background noise average. | |||
'''Position by position correction mode:''' each source position in relation to its background noise equivalent. | |||
======K1 measurement determination====== | |||
The measurement method allows you to measure the K1 value. | |||
The Standard requirements are for user information (given by the selected standard). | |||
[[Image:Sp_corrections_06.png|framed|none]] | |||
You have two possibilities to do the Measurement: | |||
'''One position for all:''' determines the K1 only for one position then the value is assigned to all positions (select the position number). | |||
'''All positions:''' determines the K1 for each position. | |||
Double click on the '''Correction mode''' setting, the following window is displayed: | |||
[[Image:Sp_corrections_07.png|framed|none]] | |||
'''Average correction mode:''' source average in relation to the background noise average. | |||
'''Position by position correction mode:''' each source position in relation to its background noise equivalent. | |||
=====K2 correction===== | =====K2 correction===== | ||
This type of correction is about the measurement environment. | This type of correction is about the measurement environment. | ||
There are five methods to define the K2 correction factor (Approached method, File, Manual, Reference source or RT 60). | There are five methods to define the K2 correction factor (Approached method, File, Manual, Reference source or RT 60). | ||
The File and Manual methods are explained in the K1 topic. | |||
======K2 Approached method determination====== | |||
This type of method is mainly used for the room tests. | |||
The Standard requirements are for user information (given by the selected standard). | |||
[[Image:Sp_corrections_08.png|framed|none]] | |||
Enter the values of the '''mean absorption coefficient''' of the room (depends on the type of material constituting the room) and the '''room surface''' by double clicking on the settings. | |||
======K2 Reference source determination====== | |||
The reference source method allows you to load the K2 value from a file. | |||
The Standard requirements are for user information (given by the selected standard). | |||
| |||
[[Image:Sp_corrections_09.png|framed|none]] | |||
This method means that the sound power of the source with K2=0 was previously measured and saved in a file (get the file by double clicking on '''Ref srce Lw measured with K2=0'''). | |||
'''Ref srce Lw method''' (Manual or File): select the reference source measurement method in the measurement environment. | |||
======K2 RT 60 determination====== | |||
This type of method is mainly used for the room tests with known RT60 values. | |||
The Standard requirements are for user information (given by the selected standard). | |||
[[Image:Sp_corrections_10.png|framed|none]] | |||
Enter the values of the '''RT60''' of the room and the '''room volume''' by double clicking on the settings. | |||
