Air-conduction hearing aids transmit sound via air → eardrum → ossicles, targeting damage in the inner ear (cochlea/auditory nerve), and are suitable for individuals with sensorineural hearing loss. Common styles and forms include behind-the-ear (BTE) and receiver-in-canal (RIC) custom-fit devices—our BlueWhale, for example, is an RIC model.
Key to Fitting: Precise Diagnosis Is the Sole Prerequisite
Hearing aid fitting is a rigorous medical procedure that must be based on a comprehensive audiological assessment:
Scientific hearing aid selection follows a three-step process: First, subjective testing—using pure-tone audiometry to determine the degree and nature of hearing loss. Second, objective examination—using acoustic immittance testing, otoacoustic emissions (OAE), and other measures to evaluate middle ear and cochlear function. Third, professional evaluation—where an experienced audiologist develops a personalized intervention plan based on the patient's etiology and lifestyle needs.
With the power of AI today, self-fitting can also achieve precise diagnostics.
Choosing the right hearing aid is not just about "hearing" volume—it's about the authenticity, comfort, and hearing safety of truly "understanding" speech. When sound finds its optimal path, life can once again resonate with a beautiful melody.
