Large bore LB horn effect A 4 to 5 mm bore at the end of the canal that mimics the horn effect and helps increase high frequencies Small bore SB reverse horn effect A 1mm bore that helps boost perceived low frequencies by reducing high frequencies Open bore OB Commonly used with gently sloping high frequency losses The canal is cut short and hollowed An example is Westone s Style No 10 Earmold Fishmouth FM bell bore Not a true acoustic modification but rather a beveled cut in the end of the sound bore that acts as a cerumen trap Damping primarily affects frequencies between 1 and 3 kHz due to the effect the damper has on the resonant peaks of the hearing instrument As the name suggests the damper dampens or smooths out the frequency response of a hearing instrument As a result the sound quality of the hearing instru ment is much more natural with feedback less likely Dampers can be fit to the ear hook the earmold tub ing or the sound bore of the earmold The location determines the amount of smoothing the damper will achieve The closer the damper is to the end of the signal chain the greater its effect on smoothing response peaks The size and shape of the sound bore can also control the frequency response of the earmold hearing instrument combination Changes in bore diameter can affect frequencies at 1 5 kHz and above Larger sound bore diameters and tubing can result in a 3
