Directional microphone (near field). We'll give you a through-hole PCB board, all parts, and instructions to make your own directional microphone.  All step by step instructions and video tutorial are included via a link to our website. The case is not included in the sale.   The kit incorporates a low profile miniature, patent pending, directional microphone technology that creates a 6 foot zone which captures, focuses and clarifies conversations in noisy environments, while reducing the effects of extraneous noise. Latency (delay) imposed by digital signal processing is detrimental to the hearing impaired due to lip sync (lip reading) difficulties. For that reason we used an analog circuit design in Wear with no measurable latency. We incorporate a technology using a beam-forming array of 9 microphones that create a circular 6 foot zone. Acoustic waves generated in that zone (coherent) reach the microphones at the same time so they are amplified. Sounds from further away (non coherent) reach the microphones at different times so they are not amplified. This creates a near field to far field signal level difference of 10 to 11 db. That voice to noise ratio level difference of 10 to 11db improves the intelligibility of near field conversation.  Our research over the past two years has allowed us to reduce the size of beam forming arrays to unprecedented small form factors in a lightweight package using low power. All of this is done without digital signal processing while maintaining hi fidelity sound quality so that the Wear directional microphone can also be used for general recording applications as well as an assistive listening appliance.
