Our mobile office based in New Hope, offers a fun, comfortable and non-threatening setting to have your baby’s or child’s hearing tested.  We use objective tests as well as traditional methods.   

We ask for payment at the time of service, and do not submit insurance claims at this time. To schedule an appointment, please call 612-209-8223.

*We do not bill insurance for these services or technologies; most insurance companies do not pay for them.  But because these services and products are considered medically necessary to protect your hearing, you can use your healthcare expense account debit card.  To date, we have not had a denial of this.  If you itemize your taxes, you can deduct these fees; make sure you keep a copy of your receipts.  

**We bundle impressions and sleeves for $200.  If several musicians wanted to have this done at the same time, we would discount another $20 per artist.  

Custom Ear Protection & Sleeves

Custom ER plugs use high-fidelity static filters inserted into custom fitted silicone canal-style earmolds.  The filters can be changed out between solid plugs, versus filters offering approximately 9, 15 or 25dB of relatively flat attenuation, depending on your listening needs.  In general, you can still hear speech and other voices or instruments in a group while wearing them.

Custom sleeves can be solid (such as sleep or swim molds), or can be designed to fit over stock monitors (such as Etymotic or Shure).  Custom in-ear monitors can be built into custom sleeves (such as Sensaphonics ProPhonic or 3D Active Ambient Systems). 

Some benefits of custom soft gel silicone sleeves include: 

  • Medical grade silicone is hypoallergenic and provides a good seal
  • Better fit, comfort and retention than stock or foam options, even with jaw movement
  • Better sound isolation (up to 37dB) allows better hearing and monitoring of your mix at lower levels; better sound quality at lower levels helps to protect your hearing
  • Increased bass response due to complete seal (low frequencies leak through a poor seal)
  • Shock-absorbing silicone protects drivers
  • Very durable, resistant to cracking, shrinking or fading
  • Custom colors available  

We primarily work with Sensaphonics and Etymotic, which are Chicago-based companies. Both companies have done much of the pioneering work in this field.  Dr. Anderson attended Sensaphonics’ two-day “Golden Circle Seminar on Audiology for Musicians” in 2007 and again in 2012.  You can check out their websites:


There are many good labs and in-ear companies out there.  If you need ear impressions for custom in-ears made by another manufacture, we will be happy to help you.  Just bring in your order form and shipping information, or ship the impressions yourself.  Please refer to the information on Ear Impressions and Fees for Musicians’ Services & Technologies.

Looking to conserve and protect your hearing so you can continue to enjoy and perform the music we love? Relax in the recreational setting of my mobile office, a 27 foot Ford Coachman RV.  Your ears will be checked for wax using a standard otoscope.  If you are planning on getting custom musicians’ ear protection (ERs or sleeves for in-ear monitors), then it is a wise best-practice to have a Musician’s Baseline Audiogram done first, to document your current hearing levels.  This is a threshold hearing screening.  Frequencies of 1,000-8,000Hz are tested.  Insert earphones are used, covered by 3M ear protection earmuffs.  You should not be exposed to loud sound for 48 hours prior to our screening, or else you should use ear protection during that time. You will receive a copy of this audiogram for your records, for future comparison.  Appropriate referrals for further testing are made when indicated. 

Ear Impressions are taken for those wanting custom in-ear technologies.  Your canals must be clear to get a good impression and fit.  If there is a significant amount of wax or debris in your ear canal, you will be given a sample of Debrox, an earwax softening agent, and you will be asked to see your primary care provider to have your ears cleaned before we can take impressions and proceed with your order.  A small amount of earwax in the outer ear canal may be removed at our office with a curette.  

If your ear canals are clear, then a small foam or cotton “otoblock” will be rolled into your ear canal using a lighted speculum (a penlight with a pointy light on the end), to protect your eardrum.  We usually put a bit of ear gel on the otoblock so it doesn’t irritate your ear canal, so it may feel cold and “goopy”.  Then, we squeeze silicone impression material into your ear canal, either using a manual syringe or a self-mixing impression system which looks and works much like a calking gun. This material will “cure” or harden up in about 10 minutes. During this time you are asked to work your jaw, sing, play your instrument or mouthpiece, or do whatever you would normally do when you will be wearing your custom in-ears. 

When the impressions are set, we massage your ears and you will work your jaw to loosen the seal.  The impressions will then be gently removed from your ears.  You will sometimes feel a sense of pressure or release of pressure while this is being done, like ascending or descending in an airplane. Your ears will be examined again with the otoscope to make sure all the impression material has been removed, and that your ear canals are unchanged. 

Your silicone impressions will be returned to you after your molds or sleeves have been made. You can keep your impressions for 18 months, and send them in to the lab for another pair of ERs or sleeves, say you’ve lost yours or want to upgrade to a higher level of monitors.

Auditory Processing Disorders

Our Auditory Processing Disorders (APD) model follows a “minimal test battery”, multi-
disciplinary team approach, developed in partial fulfillment of my doctoral degree (CMU, 2005).  Colleagues, David A. Geddes, AuD and Amy Sievert O’keefe, AuD collaborated and reviewed this protocol, and their contributions are gratefully acknowledged. 

Peripheral hearing and middle ear function are measured and should be within normal limits. If hearing loss is measured, when symmetrical, auditory processing testing may be done, with modifications in protocol as needed, to account for hearing levels. However, interventions and accommodations for peripheral hearing loss should be in place for a reasonable time period before interventions or accommodations for APD would be recommended.  Auditory processing sub-types or domains sampled are consistent with recommendations by the American Academy of Audiology (AAA, 2010) and the American Speech-Language-Hearing Association (ASHA, 2005): speech-in-noise (discrimination; performance in competing and/or degraded acoustic signals), pattern processing, temporal processing and binaural processing.  Wherever possible, non-verbal tests are used soas not to confound a potentially language-based disorder with language-based testing. Two abnormal or “failed” tests are required to be considered an APD.
