Effect of Hearing Aid Labeling on Speech Understanding Measures

June 20, 2023 updated by: Sonova AG
New and experienced hearing aid users will be fit with two hearing devices. One will be labeled as an OTC (Over-The-Counter) device, the other will be labeled as a Prescriptive (i.e. professionally fit) device. Both devices will be generically programmed for a mild to moderate hearing loss. An objective speech in noise test will be completed with both devices.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 95 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Adults age 18 or older with bilateral mild to moderate hearing loss
  • Experienced users must have at least 6 months Hearing Aid experience
  • New users must have no prior hearing aid experience, defined as never owning their own devices

Exclusion Criteria:

  • Self-reported ear related pathology (otorrhea w/in 90 days, dizziness, sudden hearing loss or worsening of hearing w/in 90 days, otalgia)
  • Visible deformity of the ear
  • Chronic, severe tinnitus
  • Unilateral hearing loss
  • Cognitive impairment

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Naive listeners
Participants who have never worn a hearing aid before. This group will be tested with both sets of devices, those labeled as "OTC" and those labeled as "Prescriptive"
Device: Audeo P hearing aid labeled as "Prescriptive"
The Audeo P is a commercially available hearing aid that is fit by a hearing care professional. The devices will be labeled as "prescriptive" in view of the participant.
Device: Audeo P hearing aid labeled as "OTC"
The Audeo P is a commercially available hearing aid that is fit by a hearing care professional. The devices will be labeled as "OTC" in view of the participant.
Experimental: Experienced users
Participants who have at least six months experience wearing hearing aids. This group will be tested with both sets of devices, those labeled as "OTC", and those labeled as "Prescriptive"
Device: Audeo P hearing aid labeled as "Prescriptive"
The Audeo P is a commercially available hearing aid that is fit by a hearing care professional. The devices will be labeled as "prescriptive" in view of the participant.
Device: Audeo P hearing aid labeled as "OTC"
The Audeo P is a commercially available hearing aid that is fit by a hearing care professional. The devices will be labeled as "OTC" in view of the participant.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Quick Speech in Noise Test (QuickSIN)
Time Frame: Day 1 of 1 day study
A speech in noise test in which participant repeats sentences in variable levels of background noise. Test result is reported as the signal to noise level at which participant can repeat 50% of the words correctly. A lower score/dB SNR (decibel Signal to Noise Ratio) level indicates better speech in noise perception. For example, a score of 0 dB would indicate that the participant can repeat 50% of the words presented when the speech signal and the noise are presented at the same level. A score of 6 dB would indicate that the participant needs the speech signal 6 dB louder than the noise in order to correctly repeat 50% of the words presented. Scores can range from negative db SNR (e.g. -5 dB, which would be a good score and indicate little difficulty in noise) to quite high (e.g. +15 dB, which would be a poorer score and indicate much difficulty in noise) In this case, the scores ranged from +2 to +18 dB.
Day 1 of 1 day study

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Satisfaction of Amplification in Daily Life (SADL)
Time Frame: Day 1 of 1 day study
Validated subjective questionnaire for experienced hearing aid users rating their satisfaction with their hearing devices in daily activities, on a scale from 1(Not at all) to 7 (Tremendously). A higher score indicates more satisfaction with hearing aids in daily life.
Day 1 of 1 day study
Expected Consequences of Hearing Aid Ownership (ECHO)
Time Frame: Day 1 of 1 day study
Validated subjective questionnaire for inexperienced hearing aid users rating their expectations of hearing aid satisfaction and performance, on a scale from 1(Not at all) to 7(Tremendously). A higher score indicates higher expectations, including higher expected satisfaction from hearing aids.
Day 1 of 1 day study
Big Five Personality Inventory
Time Frame: Day 1 of 1 day study
A validated, 44 item inventory that measures an individual on the Big Five Factors of personality. Participants rate themselves on different characteristics using a scale from 1 (I disagree strongly) to 5(agree strongly).Subscales on extraversion, agreeableness, conscientiousness, neuroticism, and openness are scored and a higher number indicates a tendency toward that particular trait.
