I'm an Audiologist.
I would really need a better explanation of what you mean by "a few incidents that disrupted my ears" -- can you please add details?
Our ears have three sections, the outer ear which is the visible area and the canal up to the eardrum; the middle ear, which is the air-filled space behind the eardrum, including the eardrum itself, and the bones that are attached to it; and the inner ear, which consists of the cochlea which is the organ of hearing, and the labyrinth, which is the organ of balance. Those inner ear organs stimulate the VIIIth cranial nerve to send auditory and equilibrium information to the brain.
Sound is a vibration that travels through the air, to our eardrum, which then travels along the chain of ossicles (bones) and then into the cochlea. Inside the cochlea are fluids that the vibrations travel through, resulting in the movement of microscopic hair cells. When those hair cells vibrate, they trigger the nerve to fire. As the sound information travels up into the brain, it gets processed and we react to it - whether instinctively (e.g. head turn to a loud bang), or consciously (e.g. speaking to respond to someone else's voice) or both.
The most easily treated type of hearing loss is called a conductive hearing loss, which occurs when the sound vibrations are not being conducted through the outer and middle ears effectively. This can be due to wax build-up or an infection in the ear canal, fluid buildup or an infection behind the eardrum, damage to the eardrum or ossicles, or thickening of the eardrum or ossicles. Some of these are remedied easily, some require medication, and other require surgery, which may not be able to fully restore the hearing.
When the outer and middle ear are clear, but the deficiency is in the inner ear or along the nerve, the hearing loss is known as "sensorineural" and is usually permanent. Damage to the inner ear hair cells is the most common cause of sensorineural hearing loss. The hair cells are very sensitive to metabolic changes and very oxygen dependent. Sometimes, a person can inherit delicate hair cells so they experience a gradual loss with age, some medical conditions and treatments can cause them to break, and of course, exposure to loud sounds can break them off.
If the nerves and brain are no able to effectively process the sound, there is a central hearing loss or a central auditory processing disorder.
Generally good health, especially cardiovascular and metabolic maintenance, good nutrition and hydration, and minimizing or avoiding noise exposure are all you can do to preserve your hearing sensitivity. If you have hearing loss a comprehensive audiological evaluation to determine the nature and degree of the loss, and an otological evaluation to determine if there are any medical options. If you have trouble processing what you hear, there are strategies you can learn to help you compensate for those difficulties.

no subwoofers in the car.
no headphones.
put cotton in your ears when they are sensitive, or wear earplugs if sound is too loud in some places.
