As people age, their voices change, and these changes can have a significant impact on their quality of life. Voice alterations can lead to social isolation and negatively affect mental and physical health. Vocal folds can become thinner and lose their tautness, resulting in inconsistent vibrations and a change in voice quality. This can manifest as a decrease in loudness, hoarseness, or vocal fatigue. While some voices may ripen and mellow with age, others may experience warbling, whispering, or difficulties in speaking. These changes are influenced by various factors, including muscle mass reduction, posture changes, and overall health. Maintaining vocal activity, staying hydrated, and keeping fit can help preserve vocal health during aging.

What You'll Learn
Vocal folds lose tone and elasticity
As we age, our voices change. This is due to a combination of factors, including the loss of tone and elasticity in our vocal folds. The vocal folds, also known as vocal cords, are two elastic bands of muscle tissue located in the larynx (voice box). They produce the sound of our voice by vibrating when air from the lungs passes through them.
Over time, the vocal folds can become thinner and lose their elasticity, affecting their ability to vibrate consistently. This results in changes in voice quality, such as a lower pitch, hoarseness, or breathiness. The loss of elasticity in the vocal folds can be attributed to neural changes associated with ageing.
Ageing also affects the gelatinous outer layer of the vocal folds, causing it to thin and reduce the overall tension or tautness of the vocal folds. This can lead to inconsistent vibrations, further altering the sound of our voice. Unfortunately, there is no way to reverse this natural loss of elasticity. However, voice therapy and surgery can help improve voice quality and strength in some cases.
It is important to note that vocal fold changes are not just limited to ageing. Various conditions can affect the vocal folds, causing similar symptoms such as hoarseness, loss of voice, and changes in pitch. These conditions include laryngitis, Reinke's edema, spasmodic dysphonia, vocal cord nodules, polyps, and cysts, and paralysis. Therefore, if you experience persistent voice changes, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
By 2050, it is estimated that 20% of the US population will be between the ages of 55 and 75, and the ageing population's voice changes will become a growing area of clinical practice. As people live longer and remain active, seeking treatment for voice disorders becomes more common. This shift highlights the increasing importance of understanding and addressing age-related voice changes.

Vocal cord anatomy can be altered
As we age, our voices change. This is due to the anatomy of our vocal cords, or vocal folds, altering over time. The vocal cords are two muscular bands inside the larynx, or voice box, that produce the sound of our voice. They are composed of twin infoldings of three distinct tissues: an outer layer of flat cells that do not produce keratin (squamous epithelium); a superficial layer of the lamina propria, a gel-like layer that allows the vocal fold to vibrate and produce sound; and the vocalis and thyroarytenoid muscles, which make up the deepest portion.
The length of the vocal cords affects the pitch of the voice, with longer and thicker cords producing a lower-pitched voice. As we age, the vocal folds can become skinnier, both in muscle and in the gelatinous outer layer. This is thought to be due to neural changes associated with senescence. The vocal folds lose their tension and tautness, and the vibration can become more inconsistent, resulting in a change in voice quality.
In addition to the changes that occur with age, the anatomy of the vocal cords can be altered in other ways. For example, DHT, an androgen metabolite of testosterone, can cause changes in the cartilages and musculature of the larynx when present in high enough concentrations, such as during an adolescent boy's puberty. The vocal folds lengthen and become rounded, and the epithelium thickens with the formation of three distinct layers in the lamina propria. These changes are only partially reversible through reconstructive surgery.
Another way the anatomy of the vocal cords can be altered is through mechanical stimulation. Studies have shown that fibroblasts exposed to mechanical stimulation have differing levels of extracellular matrix production from fibroblasts that are not exposed. This suggests that mechanical forces applied to the tissue can alter the expression levels of extracellular matrix-related genes, which in turn allows the cells present in the tissue to regulate the extracellular matrix constituent synthesis, affecting the tissue's composition, structure, and biomechanical properties.
Finally, the superficial lamina propria, also known as Reinke's Space, is susceptible to fluid accumulation due to chronic irritation and inflammation secondary to smoking. This can lead to the formation of polyps on the vocal folds, which can cause difficulty in the inherent vibration during phonation, resulting in an altered voice that is often deeper.

Ageing voices can lead to social isolation
Ageing is often accompanied by a weakening of the voice, hoarseness, or other changes in vocal quality. These changes can be caused by a variety of factors, including the thinning of the vocal folds, decreased lung function, and overall health decline. As people age, their vocal cords may not vibrate as effectively, resulting in a breathy and raspy voice. Furthermore, conditions that affect breathing, such as asthma, allergies, and COPD, can also impact vocal quality.
The impact of ageing voices goes beyond communication difficulties. As individuals find it harder for others to hear and understand them, they may withdraw from social activities and experience social isolation. This social isolation can have a detrimental effect on mental health, potentially leading to depression and a decline in overall quality of life.
The increasing longevity and activity of the elderly population highlight the importance of addressing age-related voice changes. By 2050, it is estimated that 20% of the US population will be between the ages of 55 and 75, and a significant portion of this group may seek treatment for voice disorders. The coexistence of voice disorders and hearing impairment can further exacerbate the risk of social isolation and depression in the elderly.
However, it is important to recognize that age-related voice changes do not have to lead to social isolation. Treatment options such as voice therapy, vocal cord microsurgery, and laryngeal surgery can effectively improve vocal function and quality. Maintaining good lung function through regular exercise, staying hydrated, and limiting caffeine and alcohol can also contribute to a healthier voice.
To conclude, ageing voices can lead to social isolation, but this is not an inevitable outcome. With the right interventions and lifestyle choices, older adults can maintain their vocal health and continue to participate actively in social activities, thereby enhancing their overall well-being.

Vocal changes can be slowed by staying active
Our voices change as we age. The pitch of male voices tends to elevate, while female voices tend to lower, bringing them closer together. This is due to changes in the vocal folds, which can become looser with age, affecting the tension and vibration, and resulting in a change in voice quality.
These changes are a natural part of ageing, but staying active can help to slow them down. Just as physical activity can strengthen muscles and bones, it can also keep the vocal folds strong and healthy. Vocal exercises can be particularly effective, as they can improve the flexibility and range of the vocal folds.
Singing is an excellent way to keep the vocal folds active and can be done alone or in a group. For those who are less musically inclined, there are alternative ways to exercise the voice. Reading aloud, for example, can be a simple and enjoyable way to give the vocal folds a workout. Joining a public speaking group or a drama club could also be a fun way to stay vocal while keeping socially active.
In addition to staying vocally active, it is important to maintain a healthy lifestyle. A balanced diet and regular exercise can help to ensure the body is getting the nutrients and stimulation it needs to stay strong and slow the ageing process. This can include weight-bearing exercises to strengthen bones and muscles, as well as activities that promote cardiovascular health, such as swimming or walking.
By staying active and healthy, we can slow the ageing process and maintain our vocal health for longer. This can help us to stay socially engaged and confident in our ability to communicate effectively, which is beneficial for our overall health and quality of life.

Ageing voices are stigmatised
The social stigma associated with ageing voices can lead to self-group distancing, where individuals try to improve their situation by moving away from their stigmatised group. This can manifest as a feeling of being younger than one's chronological age, allowing older adults to believe they are not the target of age-related stereotypes and discrimination. For example, older women may try to conceal their age through their appearance to avoid ageism and align with their inner, authentic selves.
The consequences of ageing on vocal quality can be socially isolating, as individuals may become hesitant to participate in social activities or interact with friends due to difficulties in speaking and being understood by others. This social isolation can lead to a decline in mental health and overall quality of life. However, modern science and technology offer various treatments to improve voice quality and mitigate the effects of ageing on the voice, including voice rehabilitation therapy and vocal cord microsurgery.
The stigmatisation of ageing voices is a complex issue, influenced by societal expectations of youthfulness and the negative stereotypes associated with ageing. As the world's population ages, it is essential to address these prejudices and create a more inclusive environment for older individuals, particularly women who face both sexism and ageism as they grow older.

Frequently asked questions
Vocal changes are common in aging adults. As we age, reductions in muscle mass and changes in posture can make it harder to produce the same sounds that once came easily. The vocal folds or cords, the complex structure that vibrates to produce the voice, can lose tone and elasticity—bowing, shrinking, or forming gaps that will change your speaking tone.
The most common voice issues in older adults are a decrease in loudness; a hoarse, raspy, or gravelly vocal quality; and vocal fatigue. These changes usually come on slowly, with presbyphonia, or “aging voice,,” striking some as early as their fifties.
There are several available medical interventions to treat an aging voice. Temporary fillers can be used to plump up the vocal folds, helping to correct the bowed shape of the cords and improve contact. There are also more permanent implant options that can be explored.
