Authors tried to find out acoustic and psychoacoustic changes of occlusion effects (OEs) in completely-in-the canal (CIC) hearing aid with 0.8 mm vent as a function of with/without vent and bony part lengths (BLs). 28 adults with normal hearing (mean ages; 24.4 years) were participated as subjects. OEs were measured by real-ear insertion gain (REIG) with CIC hearing aid when producing a vowel 'ee'. Also self questionnaires were measured. The findings were as follows; first, there were no significant differences between with and without vent. Second, when BL was increased, REIG was decreased in 800, 1,000, 1,500, 2,000 Hz. Third, when BL was increased 2 to 8 mm,psychoacoustic OE was decreased. For improving OE in CIC hearing aid with 0.8 mm, BL should be over 6 mm in averages.
