Hearing loss and the risk of falling

Hearing loss is often perceived as merely a communication impairment, yet its impact on physical safety is frequently underestimated. Scientific studies demonstrate a clear link between hearing loss and an increased risk of falling. Even mild hearing loss can triple the risk of a fall, with various biological and cognitive mechanisms interacting. This link has not only individual consequences for those affected, but also significant social and economic implications for the healthcare system.

The silent epidemic - hearing loss as an underestimated danger

The link between hearing ability and physical safety is more complex than is commonly assumed. Whilst hearing loss is primarily regarded as a communication problem, research findings from the Johns Hopkins School of Medicine clearly show that even minor hearing impairments can have a massive impact on the risk of falling.

Prevalence of hearing loss in Germany

Hearing loss is not an isolated, marginal phenomenon, but a widespread issue that is on the rise. The exact number of people with hearing impairments in Germany is difficult to determine, as different studies use varying criteria for definition. Nevertheless, current estimates point to a clear trend. According to a study from 2015, around 10.4 million adults in Germany were affected by hearing loss. Other sources, such as the German Association for the Hard of Hearing, estimate the number of people with hearing impairments in 2018 at 15.7 million people over the age of 14. The EuroTrak hearing study from April 2025 found that over 9 million adults consider their hearing to be impaired. Prevalence rises dramatically with age. Whilst around 20 per cent of the 60 - 69 age group are affected, over 40 per cent of those aged 70 - 79 already suffer from hearing problems. Among those over 80, the figure is even higher at more than 70 per cent. The general decline in hearing ability, also known as age-related hearing loss or presbycusis, begins as early as between the ages of 40 and 50 and becomes noticeable from the age of 60, when the hearing threshold rises by around 1 decibel each year.

Why the ear does more than just enable hearing

The human ear is a highly complex organ that functions far beyond mere sound perception. The inner ear houses both the hearing organ and the vestibular system, which is responsible for balance and spatial orientation. This anatomical proximity is no coincidence, but reflects the close functional link between hearing and balance. The vestibular system consists of three semicircular canals and two balance organs (the utricle and saccule), which continuously transmit information about head position, acceleration and rotational movements to the brain. These structures are closely connected to the hearing organ via nerve pathways and are subject to the same age-related changes. Both systems are connected via a shared blood supply and nerve pathways, which is why a dysfunction in one area can also affect the other.

Statistical links between hearing loss and falls

The evidence regarding the link between hearing loss and the risk of falling is clear and concerning. Research studies show that people with a hearing loss of 25 decibels already have a threefold increased risk of falling. This risk rises progressively: with every additional 10 decibels of hearing loss, the risk increases by a further 40 per cent, or 1.4 times. The MSD Manual explicitly lists hearing loss as a condition that contributes to the risk of falling. This scientific recognition underscores the importance of the link between hearing and physical safety. Older people are particularly affected. From the age of 60, the hearing threshold increases by around 1 decibel each year, meaning that the risk of falling rises continuously. This progressive deterioration is a dynamic process that progresses over time in most people and can have serious consequences.

How hearing loss increases the risk of falls - the complex mechanisms

The mechanisms through which hearing loss influences the risk of falling are diverse and interlinked at various levels. A scientific analysis identifies several key factors that explain the increased risk.

Cognitive overload due to auditory effort

People with hearing loss must expend considerably more mental energy to process auditory information. This additional cognitive load ties up brain resources that would normally be available for controlling balance and posture. The brain must constantly fill gaps in auditory information and deduce meanings from incomplete signals. This process of “cognitive overload” means that less attention is available for monitoring posture and coordinating movements. Particularly in complex situations, such as walking on uneven ground or holding a conversation at the same time, this allocation of resources can become critical. Research also shows that untreated hearing loss is linked to an increased risk of dementia and cognitive decline. Mild hearing loss can double the risk of dementia, moderate hearing loss can triple it, and severe hearing loss can even increase it fivefold. The reduced mental stimulation and processing caused by hearing impairment can have a negative impact on brain function and lead to a breakdown of cognitive structures, which further increases the risk of falls.

Loss of auditory cues and feedback

Sounds serve as important spatial reference points and warning signals. The human brain uses auditory information to determine the position of objects, obstacles and other people in a space. People with normal hearing can, for example, use approaching vehicles, the footsteps of others or the echo of their own movements to orient themselves. With hearing loss, these acoustic anchors are missing. Those affected must rely more heavily on visual information, which can lead to dangerous situations in poorly lit environments or when visibility is limited. The loss of acoustic feedback from one’s own movements is particularly problematic, as these sounds provide important information about gait stability and ground conditions. The body needs walking or running sounds as acoustic feedback to control posture and movement patterns. With age-related hearing loss, this source of information can dry up, which can cause posture and walking problems as well as an increased risk of falling. This becomes particularly important in compensating for age-related functional decline in the vestibular system.

Reduced awareness of the environment and reliance on other senses

People with hearing loss are more likely to overlook warning signals from their surroundings, such as approaching vehicles or the footsteps of others. This leads to an increased likelihood of tripping or being taken by surprise by obstacles. The environment becomes more dangerous when important auditory warning signals cannot be perceived. At the same time, people with hearing loss are forced to rely more heavily on other senses, particularly sight. This reliance on visual information can exacerbate balance problems in the dark or in poor visibility, as an important source of sensory information is missing.

Anatomical connection between hearing and balance

The physical proximity of the hearing and balance organs in the inner ear means that diseases or age-related changes often affect both systems. The blood supply, nerve pathways and structural components are closely interconnected. Ageing processes that lead to hearing loss often simultaneously affect the vestibular system. This can result in a dual impairment: both the auditory and vestibular systems are functionally compromised. Symptoms such as dizziness, balance disorders and hearing loss may occur together.

Specific risk groups and aggravating factors

Certain groups of people and health conditions further increase the risk of a combination of hearing loss and the risk of falling. A holistic consideration of these factors is essential for prevention.

Diabetes as a double risk

Diabetes is considered one of the main causes of hearing loss after age-related hearing decline. People with diabetes are about twice as likely to suffer from hearing loss as those without this metabolic condition. The cause is thought to be damage to the tiny blood vessels and nerves in the inner ear, which can be caused by high blood sugar levels. High blood sugar levels can not only damage the blood vessels and hair cells in the inner ear, but also impair the vestibular system. This leads not only to hearing loss, but also to dizziness and balance problems, which significantly increases the risk of falling. Low blood sugar levels can also cause dizziness and thus increase the risk of falling.

Medicinal influences and ototoxic substances

Medications that can affect both hearing and balance represent another significant risk factor. These include certain antibiotics, diuretics and chemotherapeutic agents, which are classified as ototoxic. These substances can damage the sensitive structures in the inner ear and lead to both hearing loss and vestibular disorders. Particularly in older people, who often have to take multiple medications, the risk can be exacerbated by the combination of various ototoxic substances. Careful monitoring of hearing and balance function is therefore essential when taking such medications.

The vicious circle following an initial fall

People who have already fallen find themselves in a particular cycle of risk. A fall can lead to head injuries, which in turn can damage the hearing or balance organs. Blunt head trauma, such as that which can occur from a fall onto the head, can lead to hearing loss, tinnitus and vestibular disorders, depending on the location of the impact. At the same time, many fall victims develop a fear of falling, which leads to reduced physical activity. However, this inactivity weakens the muscles and the sense of balance, which ironically increases the risk of future falls. A vicious circle of fear, inactivity and increasing risk develops, which is very difficult to break.

Serious consequences of falls - beyond physical injuries

The consequences of a fall, particularly for older people with hearing loss, can be far-reaching beyond a temporary injury. Understanding these consequences highlights the importance of preventive measures.

Physical injuries and hospital admissions

Falls are a leading cause of serious injuries such as broken bones, particularly hip fractures, and head injuries. Hearing loss can increase the likelihood of such accidental injuries by up to 50 per cent. This statistic highlights the significant risk faced by people with hearing loss. The link between hearing loss and hospital admissions is particularly relevant to the healthcare system. Studies have shown that people with hearing loss experience a 47 per cent increase in hospital admissions over a ten-year period. This increased use of medical services can be seen as an indicator of systemic shortcomings. A key factor in the increased hospitalisation rates is communication barriers within the healthcare system. If patients are unable to adequately communicate their needs and symptoms due to hearing impairments, this can lead to poorer medical care and, consequently, to avoidable hospital admissions.

Psychological and social consequences

Even if a fall does not result in serious physical injury, it can have profound psychological and social consequences. Falls can trigger a fear of falling, which leads the person affected to move less and avoid social activities for fear of falling again. This reduced physical activity leads to a further weakening of the muscles and sense of balance, which increases the risk of future falls. At the same time, social isolation intensifies, as those affected leave the house less often and avoid social activities out of fear of falling. Hearing loss is associated with further psychological and social consequences, even independently of falls. Studies demonstrate a link with depression, sleep disorders and social isolation. The difficulty in following conversations often leads those affected to withdraw from social situations, which weakens their self-confidence and can lead to a feeling of exclusion.

Social and economic costs

The costs to healthcare systems are enormous. The follow-on costs of untreated hearing loss in Europe are estimated at 185 billion euros per year. This figure encompasses not only direct medical treatment costs, but also indirect costs arising from lost productivity, the need for care, and the impact on quality of life. The combination of hearing loss and an increased risk of falls further exacerbates this cost situation, as fall-related injuries can often lead to lengthy rehabilitation processes and a long-term need for care.

Holistic prevention strategies for greater safety

Given the complex risks associated with untreated hearing loss, comprehensive prevention strategies are of crucial importance. Experts agree that early detection and a proactive approach are the best ways to maintain quality of life and safety.

Early detection through regular hearing tests

Regular hearing tests are the first and most important step in prevention. An annual hearing test is recommended from the age of 50. Early diagnosis of hearing loss allows timely intervention, even before negative consequences such as an increased risk of falls or cognitive decline can manifest. Modern hearing diagnostics can also assess vestibular functions, thereby providing a comprehensive picture of inner ear health. These examinations should be carried out by ENT specialists or qualified hearing care professionals. A visit to an ear specialist, ENT doctor or hearing care professional is essential at the first signs of hearing impairment. Early detection is particularly important, as hearing loss is a dynamic process that worsens over time in most people. The earlier intervention takes place, the better the impact on the risk of falling and other associated problems can be minimised.

Hearing aids as an integral part of fall prevention

A key component of prevention is the use of hearing systems such as hearing aids. Whilst current research into the direct influence of hearing aids on the risk of falls is still ongoing and has yielded mixed results in some cases, there is clear evidence that the improvement in auditory perception provided by hearing systems can have a positive effect on balance. Studies show that hearing aids not only improve communication but also enhance spatial awareness and alertness. By providing the brain with a clearer soundscape, they help it to localise sounds and maintain balance. They help to free up cognitive resources that were previously tied up in the effort of hearing. Modern hearing aids are discreet and stylish and offer additional features that can contribute to safety. Directional hearing is improved, ambient sounds are selectively amplified, and spatial orientation is supported. Some devices have special programmes for different listening situations, which can also prioritise safety-related sounds. They are an important factor in social, emotional, mental and physical well-being.

Physical exercise and movement as fall prevention

In addition to hearing care, targeted behavioural adjustments and physical activity are crucial. Regular physical activity that trains strength and balance is an effective measure for fall prevention. Exercise not only trains balance and movement patterns but also helps regulate blood pressure, which in turn can protect the inner ear. Balance training provided by specialist physiotherapists has proven particularly effective. Yoga and Tai Chi are also effective methods for improving balance and coordination. Dancing is recommended as an ideal and enjoyable way to train balance and coordination, as it engages both physical and cognitive abilities. Strength training can help stabilise the body against sudden jolts and strengthen the muscles necessary for maintaining an upright posture. Targeted training of the core muscles and legs can significantly reduce the risk of falls.

Home adaptations for greater safety

As people with hearing loss often have to rely more heavily on visual information, adjustments to the home environment play a key role in safety. Adequate lighting is essential, particularly in areas with an increased risk of falls such as stairs, bathrooms and entrance areas. Simple measures can already lead to a significant improvement in safety. These include removing trip hazards such as loose rugs, clearing away cables and securing slippery surfaces. Installing handrails or grab bars in critical areas, such as on stairs and in bathrooms, further enhances safety. Structural adaptations include marking steps and landings, fitting non-slip surfaces and installing supports such as stair railings. Vibrating warning systems can replace audible warning signals and alert users to hazards. Other aids such as walking aids, non-slip soles or fall alarms can further reduce the risk of falls. These technical solutions complement medical treatment for hearing loss and create a safer living environment.

Additional protective measures and lifestyle adjustments

In addition to the main prevention strategies, there are other important measures that can help protect against the risks associated with the combination of hearing loss and the risk of falling.

Protecting hearing through preventive measures

Protecting your hearing by wearing ear protection in noisy environments is a fundamental preventive measure. Noise-induced hearing loss is one of the most common causes of hearing loss and can be prevented by consistently wearing ear protection. This is particularly important for people who are exposed to loud noises at work or in their private lives. Good blood circulation is essential for the function of the delicate structures in the ear, so maintaining healthy blood pressure can help protect the inner ear. Regular physical activity and a healthy diet contribute to maintaining healthy blood pressure.

Education and support from the social environment

Educating relatives about the importance of treating hearing loss in older family members is of great significance. Family members can help encourage those affected to consider hearing aids and to have regular hearing tests carried out. The social environment can also help to create a safer living environment and assist in implementing preventive measures. Open communication about hearing problems and their effects can prevent stigmatisation and encourage a willingness to seek treatment.

Research and future developments

Research into the link between hearing loss and the risk of falls is still ongoing. Further studies are needed to fully understand the relationship between different degrees of hearing loss and the effects of hearing aids on balance. There is also hope for future medications that could slow down the ageing process of the vestibular system. These developments could open up new possibilities for preventing hearing loss and the associated risks of falling in the future. The integration of various prevention strategies - from early hearing aids and environmental adaptations to targeted physical training - offers the best protection against the risks associated with the link between hearing loss and an increased risk of falling. Only through a holistic approach can the far-reaching societal costs of untreated hearing loss be reduced and the quality of life of those affected be sustainably improved.
