    These thresholds are plotted on a standard graph called an audiogram. The AVANT Audiometer software controls the hardware, stores the data (if running within NOAH or TIMS) and prints a standard audiogram report.
  • Page 12 NOTE: If the threshold at 2000 Hz is more than 20 dB different (less than or greater than) the threshold at 1000 Hz, repeat steps 5 through 8 at 1500 (the “half octave” between 1000 Hz and 2000 Hz). 11. Repeat steps 5 through 8 for 4000 Hz, 8000 Hz, 500 Hz and 250 Hz. 12.

    QuickSIN (Optional) The primary complaint of hearing-impaired persons is difficulty hearing in background noise. The measurement of SNR loss (signal-to-noise ratio loss) is important because speech understanding in noise cannot be reliably predicted from the pure tone audiogram (Killion & Niquette, 2000). The QuickSIN test was developed to: Provide a one-minute estimate of SNR loss.

Once tinnitus assessment is complete, you can use modulation by: Activating the channel in which the tinnitus assessment was performed. Enter the modulation tab on the right side of Tinnometer software.
