Intended Use
The Concha Sol Hearing Aids are intended to amplify sound for individuals 18 years of age or older with perceived mild to moderate hearing impairment. They are adjusted by the user to meet the user's hearing needs. No pre-programming or hearing test is necessary. The device is intended for use without the assistance of a hearing care professional.
Device Description
The Concha Sol OTC Hearing Aids (Model CL-1001) are receiver-in-the ear, self-fitting, wireless air conduction hearing aids (§ 874.3325) intended to amplify sounds in the environment for adult users who have a perceived mild-to-moderate hearing loss. The hearing aids include Ear Tips, Carry Case and the Concha Labs mobile application. The device is indicated for over-the-counter sale (product code QUH) and integrates user input with a self fitting strategy, enabling users to independently derive and customize their hearing aid fitting and settings. Self-fitting wireless air-conduction hearing aids are Class II medical devices. The Self-Fitting hearing aids incorporate microphones for audio input, and sound is delivered to the ear via a receiver that can be coupled with domes. The mobile application contains a self-fitting software known as Soundscope, an innovative software that uses the NAL-NL2 programming formula used globally by hearing aid manufacturers. The hearing profile/personalization system in the Concha Sol Hearing Aid assesses the individual's hearing levels across a frequency spectrum in order to generate and customize the device's amplification specific to their hearing needs. The self-fitting software also assesses the individual's hearing preferences to help fine-tune the device's amplification. In addition to hearing aid functionality for environmental and directive listening; the hearing aids can also be used for telephony and streaming audio from a Bluetooth® compliant mobile device. The hearing aids are powered using Zinc Air size 312 cell batteries.
More Information

Not Found

No
The description mentions "innovative software that uses the NAL-NL2 programming formula" and a "hearing profile/personalization system" that assesses hearing levels and preferences. While this involves sophisticated algorithms for self-fitting, the summary does not explicitly mention or describe the use of AI or ML techniques like neural networks, deep learning, or training data sets for model development. The focus is on a known programming formula and a rule-based personalization system.

Yes

The device, Concha Sol OTC Hearing Aids, is a therapeutic device intended to amplify sound for individuals with hearing impairment, directly addressing a health condition.

No

The Concha Sol Hearing Aids are intended to amplify sound and assess hearing levels to customize amplification, but their primary purpose is amplification for individuals with perceived hearing impairment, not the diagnosis of a medical condition.

No

The device description explicitly states that the hearing aids include microphones for audio input and a receiver to deliver sound to the ear, which are hardware components. It also mentions the hearing aids are powered by batteries. While there is a mobile application with self-fitting software, the device itself is a physical hearing aid with integrated hardware.

Based on the provided information, the Concha Sol Hearing Aids are not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
  • Concha Sol Function: The Concha Sol Hearing Aids are designed to amplify sound for individuals with perceived hearing impairment. They work by receiving sound from the environment, processing it, and delivering it to the user's ear. This is a direct interaction with the user's auditory system, not an analysis of a biological specimen.
  • Intended Use: The intended use clearly states "to amplify sound for individuals... with perceived mild to moderate hearing impairment." This is a functional aid, not a diagnostic test.
  • Device Description: The description details microphones, receivers, and software for sound processing and amplification. It does not mention any components or processes for analyzing biological samples.
  • Performance Studies: The performance studies focus on usability, self-selection, and clinical performance related to speech understanding and hearing aid benefit. These are assessments of the device's effectiveness in its intended function, not diagnostic accuracy based on biological samples.

Therefore, the Concha Sol Hearing Aids fall under the category of a medical device that provides a therapeutic or assistive function, not an In Vitro Diagnostic device.

Description of the test set, sample size, data source, and annotation protocol

The Usability / Human Factors validation test included 15 representative users ranging in age from 25 – 76 (median age of 70) and included 10 females/5 males with 2/3 of all participants aged 60 and above. Five participants self-described a mild hearing loss and 10 indicated a moderate with 9/15 indicating no prior hearing aid experience.
The Self-selection validation study included 27 potential consumers.
The clinical investigation study included 21 participants (13 men, 8 women). Their mean age was 66.2 years (median 73.0 years). 17 users were inexperienced with hearing aids, and 4 were experienced. Audiometric measures were taken to confirm perceived mild-to-moderate hearing status.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Human Factors/Usability:
Study type: Formative Studies (1, 2, and 3) and Summative Human Factors Validation Tests (2 primary studies).
Sample size: 15 representative users (Human Factors/Usability validation test); 27 potential consumers (Self-selection validation study).
Key results:
"After analysis of data per pre-specified 'success' outcomes it was determined that the Concha Sol Hearing Aid and Concha app are able to be used correctly by the intended users under the anticipated condition of use."

Clinical Performance Testing:
Study type: Within-subject, randomized, crossover study design of the clinical investigation.
Sample size: 21 participants.
Key results:
Effectiveness: Quick Speech-in-Noise (QuickSIN) Test and Abbreviated Profile of Hearing Aid Benefit (APHAB) were used. For the clinical study to be deemed successful, the SELF-FIT method needs to yield outcomes (namely QuickSIN and APHAB scores) which are comparable to the CLIN-FIT method, with margins of 1.8 dB for QuickSIN benefit and 9.9 for APHAB. "For both assessed endpoints, the study results indicated comparable performance and satisfaction outcomes as revealed from clinical data as compared to the same hearing aid fit by a clinician."
Safety: "No device-related or other adverse events were observed over the course of the study. Also, no health-related issues due to device fit or discomfort were observed, and no device failures leading to potential safety issues were observed."
