                                        I’d like to recognize and thank the Program Task Force (see page 2). And a special thank you to Lynnette Bardolf who
                                        both stepped in early as Program Chair AND agreed to serve in the role for next year (until the 2022 conference).
                                        Thanks also to Dee Hightower for getting us off to a running start with this year’s conference.

                                        Thanks to our Annual Sponsors, TSI Inc., Starkey, ASHA, Benson Medical Devices, Moldex-Metric, Inc., NIDCD –

                                        We have combined conference sponsorship with commercial membership to create more value and greater interac-
                                        tion between our sponsor organizations and NHCA members.

                                        As you can tell by the variety of airport codes that we can use, this year’s conference offers more flexibility than
                                        ever! The virtual conference allows flexibility to attend by blocking off 2 ½ days (don’t forget our Thursday after-
                                        noon roundtables and Thursday evening happy hour) OR to attend part of each day OR to consume all content on-
                                        demand. Whatever works for you!

                                        Please see pages 8-9 of this Supplement for more info on how to attend.

                                        Whichever virtual airport you land at, you’ll find your fellow NHCAers and lots of first-time attendees there to
                                        welcome you!

Hi Everyone!

I am Dr. Lynnette Bardolf, and I am this year’s Program Chair for the first (and hope-
fully only) 2021 NHCA Virtual Conference. The Conference is being held right in the
comfort of your own homes this year! We are very excited about this year’s Virtual
Conference, and what NHCA has to offer the Conference attendees. Even though
this year’s Conference will be quite unusual compared to what we have been used
to in the past, we are still coming together virtually, via Crowdcast and Zoom, and
doing our part to help everyone stay healthy this year. And with that, we plan to do
our best to make this Virtual Conference a rewarding experience for all.

To kick things off starting Thursday afternoon (since we aren’t having workshops
this year), we have several interactive “hot topic-Zoom rooms” planned, each last-
ing 20 mins each. These will give attendees the opportunity to engage with others
in relevant topics that are current in the world of Hearing Conservation. And the best part about the Zoom rooms is
that you will be able to attend any, or all, that you wish to attend on Thursday afternoon.

Following the interactive Zoom rooms will be a Thursday evening “Meet and Greet,” which is a “happy-hour” social
event (note: as you have probably suspected, you will need to provide your favorite beverage). The Thursday evening
meet and greet will allow Conference attendees to engage with others who will be attending the Conference, as well
as to meet the students who are attending the Conference this year. Other social events and happy hours will also be
made available during the conference.

Not only are we going to have some great live session lectures by several of our NHCA favorites, but we also have
great breakout session lectures planned, and a Gasaway lecture brought to us this year by the one and only Don
Finan. In addition, we will be wrapping up the conference on Saturday with the ability to earn additional CEUs by inter-
acting with the poster presenters as well, and with a Ted Talk. The Ted Talk is called “The Birth of a Word,” by Deb Roy
and will include a moderated discussion time for interaction after the talk.

During this Conference, we have planned for you a fun Vendor event on Saturday, which will feature some trivia! Who
doesn’t like a little trivia?

So, get comfy, put on your slippers and your patience, and enjoy the Conference this year. And even though we can’t
do the things we would normally do together at an NHCA Conference in person this year, we can still have some
Crowdcast and “Zoom-time” fun together, to make this the best virtual experience ever – and at a fraction of the cost!

Those of us on the NHCA Program Task Force Committee and on the Executive Council have all worked hard to make
this Conference engaging for all, despite the challenges of COVID-19, and it being virtual. With this in mind, we would
all like to thank you in advance for your support and we hope that everyone enjoys their Virtual Conference experi-
ence this year! And as you attend the Conference this year, please keep in mind that these are new waters we are all
traversing together for the first time! So, let’s all hop in the boat together, grab your paddles, and let’s navigate these
                                                                                                                              NHCA Spectrum Vol. 38, Suppl. 1, 2021

                                        Sometimes crowdcast needs you to validate your email so check your inbox if you aren't put right into the meeting!
                                                     Make sure to type your name as you’d like it to be visible to other attendees.


STEP 4: Sit back, relax, and enjoy the presentation! We are using a
one-way streaming platform which means you as an attendee will
not be able to unmute or come on camera without NHCA inviting
you, this is done in order to make sure there are no interferences
with the live presentations.
    • Don’t forget to take advantage of the “ask a question” feature to ask session specific
      questions to the live speakers and use the chat feature to interact and communicate
      with other conference attendees.

           TIPS AND TRICKS
  • When you receive the know before you go email on February 22nd, make sure to follow the
		 above steps early in the week so you may familiarize yourself with logging in and accessing
		 the sessions. It will make the day-of much smoother!

  • Always make sure to use the GOOGLE CHROME internet browser for the best experience
			 ° Make sure you have the Learning Center open in only ONE tab.
				 If you have multiple tabs open, you will hear a lot of echoing.

  • Make sure you have a strong internet connection, if your wi-fi is unreliable we recommend that
		 you hard-line/direct ethernet into your computer for the best streaming experience
			 ° To help increase your wi-fi bandwidth, disconnect other devices such as an Alexa,
				 Google Home, Smart TV, etc. and exit as many tabs and open applications (Teams, Slack, etc.)

  • The TED Talk and its associated discussion, and the poster session are intended to be more
		 interactive. Therefore they will be will be hosted on Zoom and you will be provided with a link to join
		 these meetings within the learning center
                                                                                                             NHCA Spectrum Vol. 38, Suppl. 1, 2021

                                        NHCA is conferring this award to the CDC NIHL Workgroup for their recent high-profile activities. They include: From 2018 to 2019 CDC’s NCEH group
                                        worked to develop unique communication tools highlighted as part of the Superbowl and posted throughout the Atlanta Jackson-Hartsfield Airport
                                        to raise the awareness of travelers regarding the hazards of high levels of noise. Similar advertisements were featured in the programs for NBA’s Allstar
                                        game, NASCAR and Indy-car racing events, and the NHL games in Atlanta. In the fall of 2019, animated images to instruct people about how to properly
                                        fit an earplug and a short video about NIHL were developed. These formed the basis of two communication products featured on the large displays in
                                        Times-Square in New York City during the 2019 Thanksgiving Day festivities and the 2019 New Year’s Eve celebration. More than a million persons had
                                        opportunity to learn about how to protect their hearing because of these efforts!

                                        Previously, the CDC NIHL Workgroup has also been active. In 2017, they published the Vital Signs article NIHL Among Adults – United States 2011-
                                        2012 in the Morbidity and Mortality Weekly Report. Several infographics were created to accompany this article to communicate the magnitude of NIHL
                                        in the U.S. Also in June 2017, they organized and hosted the Public Health Grand Rounds: It’s Loud Out There: Hearing Health Across the Lifespan.
                                        NCEH, NIOSH, Dangerous Decibels and the World Health Organization each presented reaching more than 90,000 persons worldwide!

                                        The CDC’s Noise Induced Hearing Loss Workgroup is an outstanding example for the 2021 NHCA Media Award.
