Hearing loss is a common condition that affects individuals of all ages, from newborns to the elderly. It refers to a partial or complete inability to hear sounds in one or both ears. Understanding the different types of hearing loss is crucial in providing appropriate treatment and support. In this article, we will explore three main types of hearing loss: sensorineural, conductive, and mixed hearing loss.
Sensorineural Hearing Loss
Sensorineural hearing loss is the most common type of permanent hearing loss. It occurs when there is damage to the inner ear or the auditory nerve pathways that connect the ear to the brain. This type of hearing loss can be caused by various factors, including:
- Aging: As we age, the delicate structures of the inner ear can deteriorate, resulting in sensorineural hearing loss.
- Noise Exposure: Prolonged exposure to loud noises, such as working in noisy environments or attending loud concerts, can damage the hair cells in the inner ear.
- Genetics: Some individuals may inherit genetic mutations that make them more susceptible to sensorineural hearing loss.
- Medical Conditions: Certain medical conditions, such as Meniere’s disease, otosclerosis, or tumors, can contribute to sensorineural hearing loss.
- Medications: Certain medications, such as certain antibiotics or chemotherapy drugs, may have ototoxic effects and damage the inner ear.
Conductive Hearing Loss
Conductive hearing loss occurs when sound waves are unable to reach the inner ear effectively. It is often caused by problems in the outer or middle ear that obstruct the transmission of sound. Common causes of conductive hearing loss include:
- Ear Infections: Infections in the middle ear, such as otitis media, can cause fluid buildup and interfere with sound transmission.
- Earwax Impaction: Excessive earwax can block the ear canal and prevent sound waves from reaching the eardrum.
- Ear Canal Blockage: Objects lodged in the ear canal or abnormal growths, such as tumors or bony growths, can obstruct sound transmission.
- Perforated Eardrum: A hole or tear in the eardrum can disrupt the conduction of sound waves.
- Abnormalities in the Middle Ear: Conditions like otosclerosis, where the middle ear bones become immobilized, can cause conductive hearing loss.
Mixed Hearing Loss
Mixed hearing loss refers to a combination of sensorineural and conductive hearing loss. It occurs when there is damage to both the inner ear and the outer or middle ear structures. Individuals with mixed hearing loss experience a combination of difficulties in sound perception and transmission.
The causes of mixed hearing loss can be a combination of the factors mentioned above for sensorineural and conductive hearing loss. It can result from chronic ear infections that lead to damage in both the middle ear and the inner ear structures or from a combination of age-related deterioration and ear canal blockage.

Diagnosis Process for Hearing Loss
When an individual experiences symptoms or suspects a loss of auditory function, a comprehensive diagnostic process is crucial. This process typically involves the following steps:
Medical History Evaluation: The healthcare professional will inquire about the individual’s medical background, including any known risk factors, exposure to loud noises, previous ear infections, or family history of auditory issues.
Physical Examination: A physical examination of the ears, known as otoscopy, is performed to assess the condition of the ear canal, eardrum, and outer ear.
Hearing Tests: Various tests are conducted to evaluate the individual’s auditory abilities. These tests may include pure-tone audiometry, speech audiometry, tympanometry, and otoacoustic emissions (OAE) testing.
Audiogram Interpretation: The results of the hearing tests are plotted on an audiogram, a visual representation of an individual’s hearing thresholds across different frequencies. This chart helps determine the type, degree, and configuration of auditory impairment.
Further Diagnostic Measures: In some cases, additional tests, such as auditory brainstem response (ABR) testing or imaging studies, may be recommended to assess the auditory pathways or identify any underlying structural abnormalities.
Consultation and Treatment Planning: Based on the test results, the healthcare professional will discuss the findings with the individual and recommend suitable treatment options. These may include hearing aids, assistive listening devices, medical interventions, or referral to specialized healthcare providers.
Audiogram for Diagnosing Auditory Impairment
An audiogram is a standardized graph used to illustrate an individual’s hearing thresholds at different frequencies. This tool plays a crucial role in diagnosing and categorizing auditory issues. By displaying the results of pure-tone audiometry, where individuals listen to a range of tones at varying frequencies and loudness levels, the audiogram helps determine the softest sounds they can perceive at different frequencies.
The audiogram features a horizontal axis representing frequency, measured in Hertz (Hz), ranging from low to high pitches. The vertical axis represents sound intensity or loudness, measured in decibels (dB), ranging from soft to loud sounds. The results are plotted as symbols on the graph, with each symbol indicating the individual’s hearing threshold at a specific frequency.
Analyzing the shape and pattern of the symbols on the audiogram allows healthcare professionals to identify the type of auditory impairment (e.g., sensorineural, conductive, or mixed) and its degree (e.g., mild, moderate, severe, or profound). This information is crucial for developing appropriate treatment plans and interventions.
Newborn Hearing Loss Screening
Screening newborns for auditory impairments is a vital step in early detection and intervention. These screening procedures aim to identify potential hearing problems shortly after birth, enabling prompt support for infants with auditory challenges and facilitating their language development and overall well-being.
The most common screening method is otoacoustic emissions (OAE) testing. This non-invasive test involves placing a small probe in the baby’s ear and playing sounds through it. The device measures the echo produced by the inner ear in response to the sounds. If the OAE response is absent or weak, further diagnostic testing, such as auditory brainstem response (ABR) testing, may be recommended to determine the degree and type of auditory impairment.
Newborn hearing loss screening is typically conducted before the baby leaves the hospital or shortly thereafter. It is a routine procedure that helps ensure early intervention and support for infants with auditory impairments, enabling them to access appropriate treatments and services during the critical stages of development.
