We are interested in working with individuals with and without hearing loss who would like to participate in research. All of our research participants are compensated for their time and offered counseling about their auditory abilities as part of their involvement in our studies.

Northwestern University Hearing Aid Lab Studies

We are seeking research participants for the following studies:

A hearing aid research study at Northwestern University

Hearing aids are customized to your hearing abilities. Could where you listen affect the hearing aid fitting too?

The focus of the study is on listening environments. Audiologists ask patients to describe their listening experiences, and the audiologists use that information to adjust the hearing aids. Our goal is to develop a predictive model in which the hearing aids could use your hearing ability and listening environments to customize advanced features and improve communication.

Individuals interested in this study will have their hearing tested and complete a brief cognitive assessment to determine eligibility. We will ask you to complete questionnaires about your listening experiences and hearing loss.  During the study, you will wear study hearing aids daily for approximately 5 weeks. We will ask you to complete short surveys (less than 1 minute) about your listening environments on a smartphone app a few times each day while wearing the hearing aids. As a volunteer in this study, you will be paid up to $300.

You may be eligible for the study if you:

  • are 18 years or older
  • are not currently using hearing aids
    • You will be screened to confirm you qualify for the study

We are seeking adults aged 50 or older with mild cognitive impairment or early Alzheimer’s Dementia and hearing loss, along with one of their communication partners (such as a family member), to participate in a hearing aid research study. We hope to better understand how cognition impacts our ability to benefit from different kinds of hearing aid processing. In part of the study, participants will wear the hearing aids at home. Most of the testing will take place on either the Evanston or Chicago campus and requires a few visits over a 2-month period. There will also be some remote visits using telehealth or video conferencing software. Listeners will be compensated for their time.

More information about participating in a study:

Our research studies wouldn’t be possible without our participants who have been so generous with their time (and ears!). Because our research focuses on how aging, cognition, and hearing loss all interact, we work with adults of all ages, and with normal hearing up to severe hearing loss.

Newspaper ads, flyers, and social media postings are the most common way people first hear about us. We are lucky that some of our participants enjoy the process so much that they share their experience with friends and family.  We may also contact you if you’ve entered your name in a research registry, where people interested in research participation sign up to be contacted when they meet the criteria for studies.

Besides a general interest in research, people are drawn to our studies because they are interested in a specific topic. Other times a participant may have a desire to find out more about their own hearing abilities. We are a research lab and do not sell hearing aids, but our research staff includes licensed audiologists who can counsel a participant about their test results, recommend next steps for clinical care, and provide appropriate referrals.

The first step when someone is interested in a study is to contact us, either via phone or email. We will review the study criteria to see if the person is eligible for the study. In many cases, we may schedule a screening appointment to confirm eligibility.

After reviewing and signing the consent form, we will take a detailed hearing health history, complete a hearing test, and perform a cognitive screening. Some studies may have additional screening requirements. Most studies involve a listening task. For example, a participant might wear earphones or hearing aids while listening to speech in noise.

Our studies are based in Evanston or Northwestern’s medical campus in Chicago.

Our current studies can be found here. We are also happy to discuss our studies, either via phone or email.
