Does wearing one earbud increase the risk of deafness?

I often wear only one earbud. Recently, I've noticed quieter sounds seem like hearing loss. Can wearing one earbud cause deafness? (Long Nguyen, 40, Ho Chi Minh City)

Answer:

Sound enters the ear and vibrates the eardrum, transmitting through tiny bones in the middle ear to the cochlea, which contains hair cells. These hair cells convert mechanical vibrations into electrical signals, which are then sent to the brain via the auditory nerve. The brain processes these signals, allowing us to perceive and understand sound.

Wearing one earbud for extended periods subjects that ear to the full intensity of the sound. The constant stimulation can overload and damage the hair cells, reducing their sensitivity to vibrations. The brain then works harder to compensate for the other ear, potentially leading to an imbalance in hearing over time.

When using a single earbud and struggling to hear, you tend to increase the volume. Hearing loss can occur with volumes of 100 dB for 15 minutes or above 85 dB for eight continuous hours. A safe listening level is generally below 80 dB.

Hearing damage is often gradual. Initial signs include difficulty hearing quiet sounds like whispers or keyboard clicks, especially in noisy environments. This can progress to tinnitus, muffled hearing, or a feeling of fullness in the ear. Continued use of a single earbud can increase the risk of permanent hearing loss or deafness in one ear.

Frequent or improper earbud use can lead to gradual hearing loss. Protect your hearing by limiting earbud use, keeping the volume moderate, and using both earbuds. If you experience hearing difficulties, consult an ear, nose, and throat specialist for a hearing test. Early detection and habit changes are crucial for long-term hearing health.
