Diagnosis of hearing loss
Diagnosis of Hearing Loss
Diagnosis of hearing loss (/daɪəɡˈnəʊsɪs ɒv ˈhɪərɪŋ lɔːs/), from the Greek words diagnosis meaning "through knowledge", and hearing loss, meaning "loss of the ability to hear", is a medical process used to determine whether a person has a hearing impairment and, if so, to what extent.
Definition
The diagnosis of hearing loss is a medical procedure that involves the identification and assessment of the severity and type of hearing impairment in an individual. This process is typically conducted by an audiologist or otolaryngologist.
Types of Hearing Loss
There are three main types of hearing loss: sensorineural hearing loss, conductive hearing loss, and mixed hearing loss. Each type has different causes and may require different diagnostic methods and treatments.
Diagnostic Methods
The diagnosis of hearing loss typically involves a series of tests, including:
- Pure tone audiometry: This test measures the quietest sound that a person can hear at different frequencies.
- Speech audiometry: This test measures how well a person can understand speech.
- Tympanometry: This test measures the movement of the eardrum in response to changes in air pressure.
- Otoacoustic emissions: This test measures sounds that are produced by the inner ear.
Related Terms

- Audiologist: A healthcare professional who specializes in diagnosing and treating hearing loss and balance disorders.
- Otolaryngologist: A doctor who specializes in diseases and disorders of the ear, nose, and throat.
