How Do Vents Affect Hearing Aid Performance ?

  title={How Do Vents Affect Hearing Aid Performance ?},
  • Published 2007
with an occluding earmold; data above “0” suggest a gain increase (from resonance) while that below “0” suggest gain reduction with the specific vent dimension (length and diameter). The solid line shows the result of a 6 mmlong vent, while the dotted line shows that of a 22 mm-long vent. For both vent lengths, one sees more low-frequency gain reduction as the vent diameter increases. For example, one sees that the output at 200 Hz is reduced by 7-8 dB with a 1 mm vent diameter, but as much as… Expand

Impact of the vent size in the feedback-path and occlusion-effect in hearing aids
Results indicate power variations of up to 10 dB for both feedback-path and occlusion-system in the 0 to 3mm vent diameter range, which should be taken into consideration in the design of feedback cancellers as well in fitting procedures. Expand
The vent effect in instant ear tips and its impact on the fitting of modern hearing aids
A large variation in REOG and VE both between ear tips and across subjects within the same ear tip type, and a high correlation between VE and perceived occlusion are showed, implying that the acoustics of instant tips need to be assessed and considered as part of the hearing aid fitting process to ensure that fitting targets are matched.

Use of frequency transposition in a thin‐tube open‐ear fitting
It is shown that frequency transposition improves the perception of everyday sounds and may enhance consonant recognition for some people fitted with thin-tube openear devices. Expand
Open Versus Closed Hearing-Aid Fittings: A Literature Review of Both Fitting Approaches
The occlusion effect and its consequences for perception while using hearing aids are described, and the advantages and disadvantages of open compared with closed fittings and their impact on the fitting process are addressed. Expand
Open‐canal fittings: Ten take‐home tips
These five factors combine to offer a wide range of potential patient benefits, and OC products have rapidly taken over a sizable share of the total hearing aid market. Expand

ing (inner diameter of 1.9 mm). Although the ear canal is typically occluded, the use of vents of various dimensions allows degrees of sound leakage into and out of the ear canal. StandardExpand
Feedback reduction system influence on additional gain before feedback and maximum stable gain in open-fitted hearing aids
user satisfaction and performance with hearing aids might be improved by identifying the feedback reduction system optimal for the individual patient by updating existing data on additional gain before feedback and maximum stable gain in commercially available, open-fit hearing instruments. Expand
Perceived occlusion and comfort in receiver-in-the-ear hearing aids.
Self-perceived occlusion was greatest for power domes, although average level of Occlusion did not exceed moderate occlusions on the rating scale, and perceived physical comfort was highest with the open dome and participants' own aids. Expand
The Acceptable Noise Level Benefit From Directionality for Listeners With Severe Hearing Loss
Directional microphone technology can provide the benefits of listening comfort to listeners with severe hearing loss and the ANL increased with the severity of hearing loss, and ANL and hearing loss degree were significantly related. Expand
Subjective and objective evaluation of noise management algorithms.
The results suggest that the directional microphone and the SII-based noise reduction algorithm may improve the SNR of the listening environments, and both the HINT and the ANL may be used to study their benefits. Expand


Vent configurations on subjective and objective occlusion effect.
The results showed a systematic change in the objective OE and subjective ratings of OE as the vent diameter was modified, and a significant correlation was seen between subjective rating and objective occlusion effect. Expand
Evaluation of the Computer-assisted Speech Perception Assessment Test (CASPA).
Although interlist differences have only a small effect on confidence limits, some clinicians may wish to eliminate them by excluding lists 3, 6, 7, and 16 from the test by administering one 10-word practice list before beginning the test. Expand
