Spatial Design of Hearing Aids Incorporating Multiple Vents
The main aim of this study was to investigate the shape variation in the human ear canal and the effects of venting on the spatial design of hearing aids. The second aim was to determine the design feasibility of a multiple venting hearing aid and assess the flexibility of design provided. A statistical shape model based on principal component analysis was created from a dataset of 60 left and ...
متن کاملGuidelines for fitting multiple memory hearing aids.
Fitting guidelines to determine candidacy for multiple memory hearing aids and the choice of amplification for each memory are devised by reviewing studies on the selection of amplification for different listening conditions. The guideline for determining candidacy comprises three factors: (1) difficulty hearing in acoustically diverse conditions, (2) an average high-frequency hearing loss grea...
متن کاملHow Do Vents Affect Hearing Aid Performance?
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 examp...
متن کاملSpatial Hearing in Noise of Young Children with Cochlear Implants and Hearing Aids
The primary goals of this investigation were (1) to determine the sensitivity of the Phrases in Noise Test (PINT) for identifying children with hearing loss who were at risk for educational difficulties in the classroom, (2) to examine the effects of spatial location of the speech and noise sources on the speech recognition in noise of participants using bilateral cochlear implants (CIs), bilat...
متن کاملCustomized Design of Hearing Aids Using Statistical Shape Learning
3D shape modeling is a crucial component of rapid prototyping systems that customize shapes of implants and prosthetic devices to a patient's anatomy. In this paper, we present a solution to the problem of customized 3D shape modeling using a statistical shape analysis framework. We design a novel method to learn the relationship between two classes of shapes, which are related by certain opera...
