Introduction
Meningitis is a serious infection of the membranes that surround the brain and spinal cord. It can be caused by bacteria, viruses, or fungi. Bacterial meningitis is the most serious type, and it can be fatal if not treated promptly.
One of the most common complications of meningitis is hearing loss. In fact, up to 30% of people who survive bacterial meningitis will experience some degree of hearing loss. The hearing loss can be mild, moderate, or severe, and it can affect one ear or both ears.
There are two main types of hearing loss that can be caused by meningitis: sensorineural hearing loss and conductive hearing loss. Sensorineural hearing loss is caused by damage to the inner ear or the auditory nerve. Conductive hearing loss is caused by a blockage in the ear canal or middle ear.
Sensorineural Hearing Loss
Sensorineural hearing loss is the most common type of hearing loss that can be caused by meningitis. It is caused by damage to the hair cells in the inner ear. The hair cells are responsible for converting sound waves into electrical signals that are sent to the brain. When the hair cells are damaged, they cannot send these signals to the brain, and this results in hearing loss.
Sensorineural hearing loss is usually permanent. There is no cure for sensorineural hearing loss, but there are treatments that can help to improve hearing. These treatments include hearing aids and cochlear implants.
Conductive Hearing Loss
Conductive hearing loss is less common than sensorineural hearing loss. It is caused by a blockage in the ear canal or middle ear. The blockage can be caused by a number of things, including earwax, infection, or a tumor.
Conductive hearing loss is usually temporary. Once the blockage is removed, the hearing will usually return to normal. In some cases, conductive hearing loss may be permanent.

Treatment Options
There are a number of treatment options available for people who have hearing loss caused by meningitis. These options include:
- Hearing aids: Hearing aids are small, electronic devices that amplify sound. They can help people with hearing loss to hear better.
- Cochlear implants: Cochlear implants are surgically implanted devices that bypass the damaged hair cells in the inner ear and directly stimulate the auditory nerve. They can provide a significant improvement in hearing for people with severe hearing loss.
- Speech therapy: Speech therapy can help people with hearing loss to improve their communication skills.
Prevention
There is no sure way to prevent meningitis, but there are a number of things that can be done to reduce the risk. These include:
- Vaccines: There are vaccines available that can protect against some of the bacteria that cause meningitis.
- Good hygiene: Good hygiene practices, such as washing your hands frequently, can help to prevent the spread of infection.
- Avoiding close contact with people who are sick: If you are around someone who is sick, avoid close contact with them. If you must be close to them, wear a mask.

Mimi Hearing Test (iOS and Android)
Mimi Hearing Test stands out for its ability to integrate with Apple Health and its sleek, user-friendly interface. The app provides a comprehensive hearing test, resulting in a ‘hearing age’ that offers a simplistic way to understand one’s hearing capabilities. However, some users have reported that the test may be overly sensitive to background noise.
uHear (iOS and Android)
uHear provides three types of tests – a hearing sensitivity test, a speech in noise test, and a questionnaire about daily hearing situations. These three tests combined provide a rounded evaluation of one’s hearing. However, some users have noted that instructions could be clearer, especially for those who are not tech-savvy.
HearWHO (Android)
Developed by the World Health Organization, HearWHO allows users to check their hearing regularly and track changes over time. The app is praised for its simplicity and the credibility of its parent organization. However, it does not provide as many features as some of its competitors.
Phonak Leo – Interactive Stories (iOS)
Primarily designed for children, Phonak Leo uses interactive stories to test hearing abilities, making the hearing test a more engaging experience for young users. It’s colorful and fun, but it might not provide the level of detail required for adults seeking a comprehensive hearing analysis.
Decibel X (iOS and Android)
Decibel X is not a hearing test app per se. Instead, it’s a noise meter that helps users identify potentially harmful noise levels in their environment, making it a preventative tool. It’s highly accurate and professional-grade but does not offer personalized hearing tests.
