TRAINING

01 TTF phenomenon

• Transient Threshold Fluctuation
• The result of response to burst firing or neural synchrony
• Causes sudden hearing changes on microstructures within certain critical bands
• Can be examined through micro-hearing test

02 The clinical result from high-resolution hearing examination

• Learn the height of 30 thresholds
• Thorough testing of the auditory filter (threshold band) structure
• Repeated examination on thresholds when examining 134 band
• Possible to observe TTF
• TTF phenomenon observation enables accurate identification of frequency band and height of 30 thresholds level
