How can hidden hearing loss be detected?
Cochlear synaptic lesions in HHL have not yet caused changes in hearing thresholds, and routine audiological examinations cannot detect this invisible auditory function defect.
The latest research by Professor Bernstein of the University of Connecticut in the United States proposes a new method for diagnosing HHL. They found that patients with this type of hidden hearing loss may have significant binaural auditory processing impairments despite normal hearing test results.
We know that binaural hearing plays an important role in people’s sound source localization, listening in noisy environments, and multi-person conversations. Therefore, this test simulates various scenes in daily life, sets different loudness, and observes the effect of binaural listening.
At present, the detection methods of hidden hearing loss are mainly objective methods such as ABR, FFR and cochlear electrogram. Professor Bernstein’s new method undoubtedly provides new ideas. However, in general, latent hearing loss is still in the stage of scientific research and exploration. In the future, it is necessary to further clarify its occurrence mechanism and develop relevant clinical testing technologies for its diagnosis and diagnosis.
Exposure to loud noise is the main cause of hidden hearing loss. An explosion or frequent exposure to high decibel noise may cause hidden hearing loss, especially in young people. People who regularly attend loud concerts, work in noisy environments, listen to music with headphones and eat in crowded bars and restaurants appear to be most at risk.
Unfortunately, without timely intervention and treatment, this can turn into more severe hearing loss as we age.
