[0002] Hearing aids are an assistive device widely used by people with hearing impairments. They help users better understand and communicate by amplifying sounds. With the development of science and technology, hearing aid technology is also constantly improving. Among them, bone conduction hearing aids are a special type of hearing aid device. They convert sound into vibrations and transmit them directly to the inner ear through the skull, thereby bypassing the outer ear and middle ear, providing hearing assistance for the hearing impaired.

[0003] However, traditional bone conduction hearing aids inevitably produce noise during use. For hearing aid users, the noise will interfere with speech understanding and reduce the hearing aid effect. Therefore, the present invention proposes a bone conduction hearing aid with dynamic noise reduction to solve the above problem. Utility Model Content
