Directional microphones work best in the near field, like face to face discussions, up to a distance of 1.5 meters (~5 feet). 1.5 m 1.5 m 1.5 m 1.5 m 3 4 How Do We Overcome oise and Distance Limitations? oisy environment Quiet environment oise oise oise? 1. Bring the microphone to the source, cutting the distance 2. Optimize signal-to-noise ratio (R) at the source with beam former 3. Adaptively adjust wireless transmitter signal and/or increase the gain of the receiver when the ambient noise level becomes higher 4. Reduce the receiver gain if no voice is present What technology can deliver all of this? Distance Distance Face to face discussions 5 6 1

It is the practice that based on a hearing and listening needs assessment, which includes the assessment of the hearing and listening situations, and a full audiological assessment A single product approach will in most cases not meet all listening and communication needs A complete solution is more likely to address all needs and leads to happier patients Hearing Aids Aren t Always Enough The solution will often include more than just hearing aids, as there are limitations based on physics in the capabilities of hearing aids to address all the needs. It is important to look at how hearing loss impacts the individual s whole life and that of his or her significant others, as the partner or friends. Customers need support which encompasses more than just hearing aids and involves more than just the person with hearing loss

3 % Recommended hearing aids 1/29/2016 Benefits Of the olution Approach Timing Is Everything For your client: Achievement of higher satisfaction by covering effectively more hearing situations. This will lead to: improved quality of life of the client improved quality of life of the partner better performance on the job For you, the hearing care professional: Improve your business by offering more customer satisfaction Increased referrals Position your clinic as a provider of overall solutions Though many fitters like to wait to introduce accessories, the complete solution works best when recommended at the first visit Fitting of the different components can be spread out over time, starting with the hearing aids This early introduction of the complete solution will automatically adjust the expectation level of the hearing aids only, as these are no longer the full solution Do not wait until hearing aids don t meet expectations before introducing full solution, because it is less likely to be successful ergei Kochkin Multiple Environmental Listening Utility Research has effectively shown that customer satisfaction increases if more listening situations are addressed by the hearing solution(s) ergei Kochkin: Increasing hearing aid adoption through multiple environmental listening utility. The Hearing Journal 2007; 60(11): From This Research: Customer satisfaction with hearing aids is strongly associated with what we call multiple environmental listening utility or MELU. When consumers are satisfied with their ability to function in many listening situations, their overall satisfaction is very high. When they are satisfied in few situations, their overall satisfaction is very low ituational atisfaction = Overall atisfaction More From This Research A wireless approach to increasing MELU Clearly, hearing aid performance must be improved if we are to achieve wider-scale acceptance of hearing aids as a solution to hearing loss. In an earlier paper,* a wireless solution was proposed for hearing aid wearers. This paper recommended: Miniaturized internal wireless receivers in every hearing aid implicity of operation for end-user Listening ituations atisfied Probability of recommending hearing aids as a function of multiple environmental listening utility (MELU) (n=2066) * Boothroyd A, Fitz K, Kindred J, et al: Hearing aids and wireless technology.

Provides best possible R by adjusting based on input and environment More appropriate for a wider range of Rs For remote talker, a higher advantage is desirable, especially in higher ambient noise levels For own voice and nearby signals, no advantage is required For speech in quiet conditions, 10 db advantage is still a good starting position R At Ear Level HIT Results o FM Traditional FM Dynamic FM (HIT) Words % correct (10 subjects) urrounding oise (db PL) db (A) Dynamic FM Traditional FM Thibodeau, 2007 What Is Roger?
