Abstract
An acoustically sealed earmold for a hearing aid insertable into the ear of individuals with impaired hearing can be prepared in situ employing the hydrophilic composite polymer materials described herein. Such composite materials include at least one hydrophilic polymer in a powder form and one or more liquid components of which at least one is hydrophilic and which can be polymerized with said hydrophilic polymer. The resulting earmold has a shape-retaining, non-tacky flexible consistency which allows it to be shaped further and also to be modified to accommodate a receiver adapter or external receiver. The earmold can then be cured by any of the conventional curing methods to retain its shape permanently. This method enables an audiologist to fit the earmold and evaluate the hearing aid in a single office visit.
