PBK-50, Low Pass Filter @ 750 Hz

Product Code: C170-7

           
  • This PBK-50 test has been low pass filtered at 750 Hz. The originator of this concept employed a 500 Hz low pass filter, but it is believed by many that a 500 Hz low pass filter is too difficult even for normal listeners and, therefore, tends to produce too many false positives.    
  • AUDiTEC™ has, therefore, recorded three different low-pass versions: 500, 750, & 1000 Hz. Research with the NU-6 low-pass filters supports the belief that 500 Hz is too difficult, and indicates that the preferred cut-off frequency is 750 Hz. Please select the word list(s) and filter(s) that best suits your needs    
  • Recording time 9 minutes and 21 seconds
