Reduce the prevalence and severity of disorders of hearing and balance; smell and taste; and voice, speech, and language.
At least 1 in 6 Americans currently has a sensory or communication impairment or disorder. Even when they are temporary or mild, such disorders can affect physical and mental health. An impaired ability to communicate with others or maintain good balance can lead many people to:
- Feel socially isolated.
- Have unmet health needs.
- Have limited success in school or on the job.
An impaired sense of smell or taste can lead to poor nutrition or the inability to detect smoke, gas leaks, or foods that are unsafe to eat.
Why Are Hearing and Other Sensory or Communication Processes Important?
Communication and other sensory processes contribute to our overall health and well-being. Protecting these processes is critical, particularly for people whose age, race, ethnicity, gender, occupation, genetic background, or health status places them at increased risk. The Healthy People 2020 objectives are designed to ensure that all Americans, from birth through old age, will benefit from scientific advances in prevention, diagnosis, and treatment of hearing and other sensory or communication disorders. For example:
- Approximately 7.5 million people in the United States have trouble using their voices.3 People in occupations that stress the vocal cords, such as teaching and singing, may need preventive and rehabilitative services.4
- Substantial progress has been made in the development of alternative and augmentative communication devices that help people with severe disorders communicate.

Understanding Hearing and Other Sensory or Communication Disorders
Many factors influence the numbers of Americans who are diagnosed and treated for hearing and other sensory or communication disorders.
- A wide gap in overall health exists between people of higher and lower social and economic standings. For people of lower income, decreased access to routine and specialized health care adds to this disparity.5
- Another factor is the age at which a person is diagnosed or receives intervention, such as for infants born with hearing loss.6 Nearly all U.S. States participate in programs to screen newborns for hearing loss. These programs support early and appropriate intervention services that help improve children’s social, emotional, cognitive, and academic growth.7
- Some individuals with hearing loss who could benefit from a hearing aid choose not to wear one due to the high cost or the perceived stigma of wearing an aid.8, 9
- Unhealthy lifestyle choices, such as tobacco use or long-term exposure to loud noise without hearing protection, increase the prevalence and severity of hearing loss and other sensory and communication disorders.10
Biological causes of hearing loss and other sensory or communication disorders include:
- Viral or bacterial infections
- Sensitivity to certain drugs or medications
Age may influence treatment options. For example, children as young as 12 months old with severe hearing loss are now receiving cochlear (inner-ear) implants.
As the Nation’s population ages and survival rates for medically fragile infants and for people with severe injuries and acquired diseases improve, the prevalence of sensory and communication disorders is expected to rise.11
Emerging Issues in Hearing and Other Sensory and Communication Disorders
Increases in blast exposure in combat situations have led to a dramatic rise in traumatic brain injury and ear damage in military personnel. These injuries have caused auditory disorders, such as hearing loss and tinnitus, and balance disorders, such as dizziness and vertigo. Noise-induced hearing loss may be reduced through the development of better ear-protection devices and emerging research into interventions that may protect or repair hair cells in the ear, which are key to the body’s ability to hear.
Researchers are also identifying the genetic components of many disorders, which may lead to earlier and more accurate diagnosis, classification, and long-term clinical intervention. Research is adding to the understanding of co-occurring conditions and the way the presence of 1 disorder may lead to diagnosis and treatment of another, such as diagnosing Alzheimer’s disease or Parkinson’s disease through testing of olfactory (smell) function. In addition, hearing loss may be a largely unrecognized complication of diabetes, which suggests that people with diabetes should be screened for hearing loss.12
