The effect of music on hearing

Music is a constant companion for many people in their daily lives, whether through headphones, in the car or at concerts. However, whilst music can have positive emotional effects, the question also arises as to what impact it has on hearing in the long term. Risks arise, particularly when listening at high volumes or for long periods, and these are often underestimated. Find out more here about the link between music and hearing from a medical perspective, from the effect on the inner ear to the role of the brain in processing sound.

How music is processed in the ear

The human ear is capable of perceiving an astonishing range of sounds, from quiet background noises to loud sounds at a concert. The sound waves produced by music are first picked up by the outer ear and directed through the ear canal to the eardrum. There, they cause the eardrum to vibrate, which in turn activates the ossicles in the middle ear.

The actual conversion process begins in the inner ear: the vibrations are converted into electrical impulses in the cochlea, a spiral-shaped cavity. This is carried out by specialised hair cells that respond to specific frequencies. The resulting nerve impulses travel via the auditory nerve to the brain, where they are recognised as music, processed and evaluated emotionally.

The role of volume in music

Volume, measured in decibels, is one of the most important factors when it comes to the impact of music on hearing. Even at around 85 dB, the inner ear can be damaged if exposed for a prolonged period. Live concerts, headphones at full volume or loud speaker systems can easily reach levels of 100 dB and above.

The danger lies in the fact that the hair cells in the inner ear are sensitive to excessive strain. If they are overstimulated or permanently damaged by excessively loud music, they do not regenerate. This can lead to temporary or even permanent hearing loss. Teenagers and young adults in particular, who regularly listen to music at high volumes, are at risk.

Listening to music with headphones: risks and recommendations

It is hard to imagine everyday life without headphones. They allow you to enjoy music privately and anywhere. However, the direct proximity to the eardrum and the often prolonged listening time increase the risk of hearing damage. In-ear headphones in particular can direct sound very concentratedly into the ear.

Hearing care professionals and ENT specialists advise following certain rules when listening to music through headphones:

• The volume should not exceed 60% of the maximum level.
  
• Take breaks: the ear needs rest periods to recover.
  
• Noise compensation via noise-cancelling technology can help keep the volume low.

Music genres and their typical volume profiles

Not every style of music affects hearing in the same way. Music genres such as rock, metal or electronic dance music are often listened to at higher volumes than classical or jazz. At many electronic music concerts or in clubs, the sound level is consistently above the critical threshold of 90 dB.

Interestingly, it is not only the volume that matters, but also the type of frequencies. Very low or very high frequencies place different demands on the hearing. Particularly high-pitched sounds place a greater strain on the inner ear and can contribute to selective hearing loss in certain frequency ranges.

The emotional impact of music on the brain

Music affects not only the ear but also the brain. Studies show that listening to music activates areas in the limbic system, i.e. the regions responsible for emotions. Music can evoke memories, influence moods or even trigger physical reactions such as goosebumps.

Emotional processing occurs in parallel with acoustic analysis. This means that even if hearing is impaired, an emotional response to music often remains, although perception changes. People with hearing loss frequently report that music sounds less clear or detailed, which can also affect emotional perception.

Hearing damage caused by loud music: types and symptoms

Anyone exposed to loud music over a prolonged period risks various forms of hearing damage.

Temporary threshold shift

After a loud concert or intensive use of headphones, there may be a temporary deterioration in hearing. This so-called temporary threshold shift manifests itself as muffled hearing or a slight ringing in the ear. Hearing usually returns to normal within 24 to 48 hours, provided there is rest and a break from noise.

Permanent hearing loss

Repeated exposure to noise without protection can lead to permanent hearing loss. This often affects the hair cells in the cochlea, particularly those responsible for high frequencies. The loss often begins gradually and is not initially noticed.

Tinnitus and ringing in the ears

Another possible symptom is a persistent ringing in the ears, known as tinnitus. Particularly after loud concerts or prolonged exposure to noise, a whistling, humming or hissing sound may occur in the ear, independent of external noises. In many cases, tinnitus is a warning sign of hearing overload.

Prevention: How to protect your hearing when listening to music

The best protection against hearing damage caused by music is a conscious and moderate approach to volume and listening time.

• Earplugs at concerts: Modern hearing protection products evenly attenuate the volume across all frequency ranges without significantly compromising sound quality.
  
• Take breaks from listening: The inner ear regenerates during periods of rest. Anyone who listens to music regularly should make a conscious effort to schedule quiet times.
  

Regular hearing tests: Early changes in hearing ability can be detected by a hearing test, even if no problems are yet perceived subjectively.

Music as a therapeutic tool

Despite the risks associated with incorrect use, music can also have positive effects on hearing. In auditory rehabilitation, for example, music is used specifically to train hearing ability. This applies in particular to people with hearing aids or following cochlear implant surgery.

Music therapy helps the brain to correctly process sounds again, improve speech comprehension and strengthen emotional connections to the environment. Here, music is used not merely as an acoustic signal, but as a medium that engages both cognitive and emotional processes simultaneously.

A long-term comparison of musicians’ hearing

Musicians, particularly professionals, are exposed to particular strain due to their regular activities. Studies show that, compared to the general population, they have an increased risk of tinnitus and hearing loss, particularly in the high-frequency range.

Nevertheless, many musicians also exhibit heightened sensitivity to subtle nuances in sound, indicating a highly trained ear and intensive processing in the brain. Conscious management of volume, particularly during rehearsals and live performances, is therefore essential for maintaining hearing health in the long term.

The body’s response: when music becomes a burden

The impact of music on hearing is a combination of volume, duration, frequency spectrum and individual sensitivity. The inner ear reacts sensitively to overstimulation, often gradually and initially unnoticed. Anyone who regularly exposes themselves to intense sounds should take warning signs seriously: for example, a dull sensation in the ears, ringing in the ears or the feeling that they are having difficulty understanding conversations.

A combination of education, protective measures and regular check-ups can help you continue to enjoy music as a positive part of everyday life without putting your hearing at risk.
