Peter studied hearing aid fitting at the world headquarters of Starkey Labs. He was able to have hands on training with the company’s founder, Bill Austin. He has also undergone advanced training in the smallest, nearly invisible style hearing aids, and has expanded his education by traveling to Denmark to learn directly from European hearing aid manufacturers. He continues to attend conferences and training seminars to stay current on the rapidly evolving world of hearing aid technology.

Not all hearing loss happens the same way. Some people notice sounds gradually fading, while others experience a sudden change. Conductive hearing loss is unique because it occurs when something blocks sound from reaching the inner ear. Unlike sensorineural hearing loss, which affects the nerves, this type is often temporary and treatable. Understanding what causes it can help in finding the right solution. Many common conditions, from infections to blockages, can disrupt sound transmission.
Sound waves need a clear path to travel through the ear. When something interferes with that journey, hearing can become muffled or distorted. This interference might come from a buildup of earwax, an infection, or even structural issues within the ear. Some causes are minor and easy to fix, while others require professional attention. Recognizing the source of the problem is the first step toward improving hearing. Here are some common reasons why conductive hearing loss occurs.
Earwax Buildup
Earwax is a natural defense mechanism that helps keep the ear clean and protected. However, when too much accumulates, it can block sound from passing through the ear canal properly. This can lead to temporary hearing loss that often improves after professional cleaning or at-home remedies.
Many people try removing earwax with cotton swabs, which can push it deeper into the ear. Impacted wax can cause discomfort, ringing in the ears, or a full sensation. Regular ear hygiene and professional cleanings can help prevent this issue.
Middle Ear Infections
Middle ear infections, or otitis media, occur when fluid builds up behind the eardrum due to bacteria or viruses. This fluid can block sound vibrations, leading to muffled hearing or temporary loss. Children are especially prone to these infections due to their developing ear structures. Pain, pressure, and fever often accompany middle ear infections. While some infections clear up on their own, others may require antibiotics. In chronic cases, doctors may recommend ear tubes to prevent fluid buildup.
Eustachian Tube Dysfunction
The Eustachian tubes help regulate pressure between the middle ear and the throat. When they become blocked or fail to open properly, sound transmission can be affected. This often happens due to allergies, sinus infections, or rapid changes in altitude. Many people experience ear-popping when flying or driving through mountains. When the tubes remain blocked, however, it can cause long-term muffled hearing. Treatment may include decongestants, antihistamines, or special exercises to restore function.
Foreign Objects in the Ear
Small objects can sometimes become lodged in the ear canal, especially in young children. Items like beads, food particles, or small insects can obstruct sound from reaching the eardrum, leading to sudden hearing loss, discomfort, or even infections.
Attempts to remove objects at home can push them further inside. Hearing health professionals can safely extract foreign objects without causing additional damage. Prompt removal helps restore hearing and prevents further complications.
