Multiple-user Wireless Hearing Protection Device Validation and Training System

KCF proposes to build a general wireless hearing protection device validation system with miniature, wireless in real ear microphones. The microphones will be battery-free to enable the reduction in size necessary to fit in the canal for testing with any hearing protection device. KCF has developed a low power wireless protocol that allows the microphones to run on small amounts of power that can be transferred wirelessly to them. Unlike commercial protocols, the protocol also includes multiple concurrent communication channels so that many users can be evaluated at once. The data from the in ear and external microphones will be passed wirelessly to a database, and finally to a handheld tablet computer such as an iPad.
