- Conductive hearing loss occurs when a problem in the outer or middle ear prevents the sound from reaching the inner ear.
- Common causes include earwax buildup, fluid in the middle ear, ear infections, or perforated eardrum.
- Individuals with conductive hearing loss may go through reduced sound intensity and difficulty hearing faint sounds.
2. Sensorineural Loss
- Sensorineural loss results from damage caused to the inner ear or auditory nerve pathways leading to the brain.
- The causes can be aging (presbycusis), noise exposure, genetic factors, certain medications, or medical conditions.
- Individuals who face sensorineural hearing loss often grapple with speech clarity, difficulty comprehending conversations, and hearing sounds at different frequencies.
3. Mixed Hearing Loss
- Mixed hearing loss is an amalgamation of conductive and sensorineural hearing loss where both the middle or outer ear, as well as the inner ear, are affected.
- It can occur when an individual with existing conductive sensorineural hearing loss also develops conductive hearing loss.
- Individuals with this type of hearing impairment may face a combination of symptoms from both conductive and sensorineural hearing loss.
4. Central Hearing Loss
- This type of hearing loss results from damage or dysfunction caused to the central auditory pathways in the brain.
- The causes behind this could be neurological conditions, brain tumors, stroke, or traumatic brain injuries.
- Individuals with central hearing loss may also face difficulty processing, and comprehending auditory information even when their ears are functioning properly.
5. High-frequency Hearing Loss
- It is defined as a particular type of sensorineural hearing loss where individuals face difficulty hearing high-frequency sounds.
- It is commonly linked to noise-induced hearing loss and can result from prolonged exposure to noises.
- People with high-frequency hearing loss may grapple with hearing consonant sounds, resulting in speech comprehension difficulties, especially in noisy environments.
