Title: Innovations of Maurice N Brearley in Directional Hearing Aids
Introduction
Maurice N Brearley is a notable inventor recognized for his contributions to the field of hearing technology. He is based in Williamstown, Australia, and has developed a unique patent that enhances auditory experiences for users. His innovative approach to directional hearing aids has the potential to significantly improve sound localization for individuals with hearing impairments.
Latest Patents
Brearley's patent focuses on a directional hearing aid that utilizes a pair of sensitive microphones or transducers. These microphones are strategically mounted on the user's body, spaced apart by a distance equal to one-half a wavelength of the center frequency of the desired frequency range. By summing the outputs of the two microphones, sounds coming from the direction the listener is facing are emphasized, while sounds from other directions are minimized. This design includes the option of adding a third microphone to enhance the hearing aid's effectiveness across a broader frequency range, specifically between 1-4 KHz. The final output is achieved by summing and amplifying the outputs from bandpass filters, which are designed to optimize sound reception.
