Evidence-Based Audiology

Our Commitment to Best Practices in Audiology Care

Why an audiologist's expertise is worth the investment:

At Doctors of Hearing, Inc. exceptional hearing care starts with a commitment to evidence-based best practices. Our audiologists follow nationally recognized clinical standards to ensure every patient receives accurate evaluations, personalized recommendations, and long-term support.

Clinical Standards

Guided by National Audiology Standards

Our providers practice in accordance with the best-practice guidelines and professional standards established by:

ASHA— The American Speech-Language-Hearing Association

AAA— The American Academy of Audiology

ADA— The Academy of Doctors of Audiology

These organizations set the benchmark for ethical, patient-centered, and scientifically supported audiology care.

By aligning our clinical approach with these standards, we ensure that your care is grounded in the latest research and proven clinical methods.

Ongoing Education & Professional Development

Hearing technology and treatment approaches are constantly evolving — and so are we. Our audiologists are committed to attending annual professional conventions, conferences, and continuing education courses to stay current with:

  • Advances in hearing aid technology

  • Best practices in hearing aid selection and verification

  • Improved fitting techniques and outcome measures

  • Counseling strategies that support long-term success

  • Comprehensive diagnostic methods for audiological assessment, tinnitus evaluation, and vestibular examination.

This ongoing education allows us to bring the latest innovations and clinical insights directly to our patients.

Comprehensive, Patient-Centered Care

Our best-practice approach means we focus on more than just hearing aids. We emphasize:

Accurate & Thorough Hearing Evaluations

  • A detailed case history

  • Otoscopic Examination

  • Tympanometry, Acoustic Reflex (Ipsilateral and Contralateral) Testing, and Reflex Decay Testing

  • Distortion Product Otoacoustic Emissions (DPOAE)

  • Pure Tone Threshold Testing including Air Conduction & Bone Conduction

  • Word Recognition Scores (WRS) & Speech Reception Thresholds (SRT)

  • Tone Decay Testing at 4000 Hz

  • UCL & MCL Testing

  • Speech in noise testing, tinnitus evaluations, and high-frequency testing

  • Other assessments or questionnaires including COSI, APHAB, or THI

Individualized Hearing Aid Selection

  • Learning about your lifestyle, budget, listening needs, hearing aid style preference, type of hearing loss, most suitable hearing aid brand, various levels of technology and personal goals

  • Recommendation of the most appropriate type and model of hearing aids such as RICs (receiver-in-canal), CICs (completely-in-canal), BTEs (behind-the-ear), IIC (invisible hearing aids), BAHAs (bone-anchored), or cochlear implants

  • Customization of the fit including the receiver length, receiver power, and dome size or need of custom receivers/earmolds

  • Recommendation of other accessories such as a remote mic, FM system, or TV connector

  • Assisting with requesting complimentary caption telephones

Evidence-Based Hearing Aid Fittings

  • In-person programming using advanced computer-based unique algorithms and standardized mathematical formulas to customize gain at each affected frequency carefully adjusting overall gain, maximum power output, and compression for optimal hearing

  • In person running an in-ear feedback calibration to map the ear canal acoustics, allowing maximum amplification without causing "whistling" or feedback

  • In-person professional verification of programming via real ear measurements/speech mapping

  • In-situ testing measuring hearing thresholds directly through the hearing aid for a more accurate, personalized fit that accounts for individual ear canal acoustics

Ongoing Counseling, Follow-Up Care & Support

Designed to help you and your family adapt, thrive, and learn how hearing loss affects daily life.

  • Strongly recommend additional services such as lip-reading classes or auditory training programs

  • Test box measurements (acoustical analysis of hearing aids)

  • Ongoing professional cleaning of hearing aids, minor repairs in office

  • Ongoing updates with software firmware

We believe optimal outcomes are achieved through the integration of advanced hearing aid technology, state-of-the-art equipment, and clinical expertise, and when patient and family education are combined.
