One aspect of the present subject matter includes a hearing assistance device, such as a completely-in-the-canal (CIC) type hearing aid, that includes a battery door with a microphone slit and a battery contact including a microphone port. In various embodiments, the microphone slit and the microphone port are configured to create a nonlinear acoustic path to a microphone of the hearing assistance device. In various embodiments, the acoustic path is configured to prevent earwax from blocking and/or damaging the microphone, such as during insertion, removal or cleaning of the hearing assistance device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hearing assistance device with improved microphone protection","description":"Disclosed herein, among other things, are methods and apparatus for improved microphone protection for hearing assistance devices.
