CREARE LLC — Department of Health and Human Services SBIR Phase I: NIDCD

Description

PROJECT SUMMARY This proposal responds to RFA DC in which the NIDCD is seeking to support the development of acoustic signal processing tools that have the potential to accelerate research studies and to facilitate the translation of novel algorithms for hearing aids Approximately of American adults report some degree of hearing trouble and of Americans aged and over experience bilateral hearing loss HL The hearing aid industry survey MarkeTrack VIII reports that less than in people with mild hearing loss uses amplification while only in people with moderate to severe hearing loss use amplification leaving still a large swath of the hearing impaired population without rehabilitation While the reasons for poor hearing aid adoption are diverse and complex out of pocket costs rank high as an issue to be addressed And in fact the Senate Report Language for FY appropriations strongly urges NIDCD to support research grants that could lead to less expensive hearing aids so such aids could become accessible and affordable to more people andquot As the lead federal agency promoting the nation s hearing healthcare NIDCD is actively seeking to address accessibility from the public health perspective Aside from cost one of the primary barriers to hearing aid adoption remains sound quality and the sense that hearing aids are still not quite able to meet all the needs of hearing impaired consumers Creare and its collaborators at Boys Town National Research Hospital BTNRH plan to develop and disseminate an open source audio processing platform to spur innovation in Hearing Aid HA research The result of this effort will be a user friendly portable upgradable and wearable master hearing aid MHA that will allow collaborative development and the open exchange of new processing algorithms within the broader hearing research community including both academia and industry The hardware used in the MHA has an open published design architecture using components currently available on the electronics market We envision three levels of users expert users implement and test new algorithms directly in firmware through an interface that gives them access to the basic features of the hardware audio input and output power management housekeeping etc developers users interact at the software application programming interface API level to modify parameters of the algorithms already implemented in firmware and evaluate their performance in a variety of conditions and professional users have access to pre programmed algorithms with some degree of parameter control through a simple user interface to test the relative benefits of amplification variants available with the wearable master hearing aid PROJECT NARRATIVE Over million Americans suffer from hearing loss yet the majority of those who could benefit from a hearing aid do not use one Among other reasons the cost and quality of the hearing aids are partly responsible for this disparity The proposed open source hearing aid research platform will allow researchers clinicians and students to develop new software and hardware concepts at relatively low cost to identify new hearing aid designs that will spur innovation and greatly increase access to hearing healthcare
