At how many pack-years does risk become noticeable?

Measurable from 10-15 pack-years. The first damage is often subclinical (only visible on an audiogram).

When to have a hearing test?

Ideally every 5 years after 50 in a smoker, or earlier in case of symptoms (tinnitus, difficulty in noise). Sooner if hearing is perceived as worsened.

Will tinnitus disappear if I quit?

Often improvement is reported within 3-12 months. Not always full disappearance, especially if tinnitus is long-standing.

Does second-hand smoke affect my hearing too?

Yes, moderately, especially in prolonged exposure (living with a smoker). Around 30 % more risk of sensorineural hearing loss in cohabiting non-smokers.

Do hearing aids work in ex-smokers?

Yes, no difference. But quitting before damage is advanced avoids or delays the need for aids.

Smoking and hearing: how cigarettes damage the inner ear and accelerate hearing loss

Tobacco raises hearing-loss risk by 70 %. Vascular mechanisms on the inner ear, more frequent tinnitus, recovery after quitting.

May 15, 2026 Aria

Hearing is one of the senses we lose silently. Here too, tobacco is a little-known but well-established risk factor. Smokers have 70 % more risk of developing hearing loss than comparable non-smokers.

Why the inner ear is vulnerable

The inner ear (the cochlea) contains ultra-fragile hair cells that turn sound vibrations into nerve signals. These cells do not regenerate after destruction. They depend on extremely fine microcirculation and constant oxygen supply.

+ 70 % hearing-loss risk in regular smokers, compared with comparable non-smokers, according to a Japanese cohort study on more than 50,000 people.

The concrete consequences

Smokers' hearing loss is insidious. It starts at the high frequencies, which are no longer caught in a group conversation. The family notices before the patient.

Myth vs reality

Second-hand smoke and child hearing

Passive exposure also affects children: raised risk of recurrent otitis, which can disrupt language development and cause transient hearing drops.

Recovery after quitting

A few months cochlear microcirculation recovers, tinnitus may decrease.
1-2 years hearing-degradation pace slows clearly.
Several years risk of severe hearing loss approaches that of a non-smoker.

⚠️ Important: hearing loss already in place does not heal. Destroyed hair cells do not grow back. Quitting stops degradation, but does not restore what was lost.
