Speaker(s): Roger Grinnip, Principal Acoustical Engineer at Shure Incorporated
Electrostatic transducers are mechanically simple and can provide a number of performance benefits when used in acoustic applications. However, electrostatic transducers carry a stigma, are viewed as exotic, and have not found mainstream acceptance except in condenser/electret microphones. To most, the complication seems to stem from the unique electrical requirements, but a close look at the basic operation uncovers additional complications that can impede the performance benefits. To shrink the electrostatic transducer down to an earphone driver, with optimal performance, requires recognizing these “potholes” and finding the path to compromise.
About The Presenter
Roger Grinnip is a Principle Engineer with Shure Incorporated. He’s been with Shure Incorporated for 17 years and worked exclusively on acoustical transducers, with his most recent designs ultimately becoming the KSM8 dynamic microphone and the KSE1500 electrostatic earphone. His interests include physical acoustics, structural acoustics, computational acoustics, (a little bit of) circuit design, and most other things related to electroacoustic systems.

Speaker(s): Dr. Ian Corbett - Coordinator, Audio Engineering Program, Professor of Audio Engineering and Music Technology, Kansas City Kansas Community College
Whether you have only one microphone and one recording room, or have a variety of microphones and different rooms available, it’s essential to think about the final mix well before you even get into the recording studio. Join Ian as he presents some of the ideas and concepts from his Focal Press/Routledge book “Mic It! Microphones, microphones techniques, and their impact on the final mix”. What do you need to think about before and during the recording process to optimize your tracks for your mix? What are you trying to control and capture when you record? What should your priorities be? What are the sonic, artistic, time and financial benefits of miking for the mix? Real world and every-day situations will be presented, with plenty of audio examples. For students and professionals alike, understanding these issues and techniques will increase the variety of mix styles and sounds you are able to produce, making you a more versatile audio engineer ready to meet the needs of clients and employers today and tomorrow.

Speaker(s): Mead C. Killion, PhD, ScD(hon), Founder, Etymotic Research & Stavros Basseas, PhD, Founder, Sound World Solutions
Starting in the early 1990s, FDA received repeated requests to create a category of OTC hearing aids. Mounting pressure came from consumers, consumer-advocate organizations, Institute Of Medicine (Now part of National Academy of Science), President’s Council of Advisors, several task forces, and concerned hearing professionals. Even among those adults who saw a medical or hearing professional, a recent study by Northwestern University MBA students found that 55% left the office with nothing: Eighty percent said hearing aids were too expensive and 60% said cost was the primary reason for non purchase. Finally, in August 2017 a bill establishing OTC hearing aids was signed into law.
This talk will cover the efforts of two manufacturers to bring OTC hearing aids to market, the difficulties in honestly labeling Personal Sound Amplifier Products (PSAPs) that "are not intended for hearing loss" according to FDA, and the extensive experimental evidence that the better quality one-size-fits-most PSAPs can perform nearly as well as much more expensive hearing aids for many persons. In some cases, do-it-yourself hearing aids can be easily programmed by the purchaser. At the same time, the professional input can often be as important to satisfaction with hearing aids as the doctor can be in the success of medication.
Other Business: Dinner (optional, but please RSVP) will begin at 6:30pm. Contact Ross Penniman (firstname.lastname@example.org) by Tuesday, September 11 if you would like to join us. Pizza and salad from Lou Malnati's will be provided.
