TL;DR: An earmold as discussed by the authors is a method of manufacturing an earmolds for a hearing aid that conveys amplified sound from the hearing aid into the ear canal to a closed cavity adjacent the tympanic membrane.
Abstract: An earmold and a method of manufacturing an earmold for a hearing aid that conveys amplified sound from the hearing aid into the ear canal to a closed cavity adjacent the tympanic membrane. The earmold includes an acoustic conduction tube having an external diameter smaller than the ear canal and a flexible flanged tip that exerts negligible pressure on the wall of the canal. One end of the tube is held in place in the canal by the flanged tip. The opposite end of the tube may be positioned in the ear aperture by a fitting in the ear concha that may be integral with the tube. The hearing aid and the earmold leave the canal open preferably to a point past the canal isthmus.

TL;DR: In this paper, a modular hearing aid with a base unit and detachable earmolds is presented, where a battery and earmold tip and a receiver can be integrated with the earm mold.
Abstract: The present invention relates to a modular hearing aid having a base unit and a detachable earmold. A battery, and earmold tip and a receiver can be integrated with the earmold. The earmold can also include a removably attached module. The module can have a shell, electronics, a receiver or a microphone. A hearing aid also includes a flexible hearing aid tip having a vibration isolator portion and a mushroom shaped tip portion. The vibration isolator portion mechanically decouples a receiver from a hearing aid base unit while the mushroom shaped tip portion provides an acoustic seal in the ear canal of a user. The internal components of a hearing aid can be potted to attenuate vibrations created by the receiver during operation.

TL;DR: The auditory effects of delays between bone- Conducted sound and aid-conducted sound are likely to become disturbing for delays exceeding 20 msec, and these delays are smaller than the delays at which audio-visual integration is disrupted.
Abstract: Objective:When people who wear hearing aids speak, there are three paths by which they hear their own voices: 1) through the air and leakage around the earmold; 2) via the solid structures of their head; 3) through the air to the hearing aid microphone, and then through the aid circuitry. These path

TL;DR: A new procedure is described for measuring loudness discomfort levels (LDLs) for the purpose of selecting SSPL90 characteristics of hearing aids, defined in terms of SPL developed in a 2 cm3 coupler, thus making selection from hearing aid specification sheets practical.
Abstract: A new procedure is described for measuring loudness discomfort levels (LDLs) for the purpose of selecting SSPL90 characteristics of hearing aids. The person is seated in sound field wearing a high-output hearing aid (with a known amount of 2 cm3 coupler gain) connected to a personal earmold. The loudness of frequency-specific signals is rated from a series of loudness category descriptors. The LDL is defined in terms of SPL developed in a 2 cm3 coupler, thus making selection of SSPL90 from hearing aid specification sheets practical. Experiments on LDL stability over time and validation of the SSPL90 selection are reported.

TL;DR: In this article, the earmolds are designed to fit the majority of people with the minimum number of required sizes, which can be worn within the ear in a comfortable, safe, secure manner.
Abstract: Earmolds (101, 102) for holding communications devices within the ear in a secure and comfortable manner. The earmolds (101, 102) are designed to minimize protrusion into the ear canal, while providing security by extending the helix (103a, 103b, 404) of the earmold to fit under the crux of the ear's helix. These earmolds (101, 102) are also designed to avoid a seal in the ear canal, thereby reducing discomfort, improving wearer's ability to localize sounds. These earmolds (101, 102) are designed to fit the majority of people with the minimum number of required sizes. With this design, communication devices can be worn within the ear in a comfortable, safe, secure manner.
