High-Frequency Hearing Loss: Causes and Symptoms

BY EARGO - NOVEMBER 1, 2023

 

 

High-frequency hearing loss is a prevalent condition that affects individuals of all ages but is often associated with the natural aging process. This hearing impairment primarily impacts one's ability to perceive sounds in the higher frequency range, making it challenging to hear high-pitched voices, soft consonants, and essential environmental sounds.

Whether you are personally navigating the challenges of this condition or seeking insights for a loved one, understanding the causes, symptoms, prevention, diagnosis, and treatment options for high-frequency hearing loss is vital for individuals seeking to preserve their hearing health and enhance their overall quality of life.

What Is High-Frequency Hearing Loss?

High-frequency hearing loss, also known as high-pitched hearing loss, is one of the most common types of hearing loss. People with this condition have difficulty hearing high-pitched sounds, including children’s and women’s voices, beeping devices, birds singing, and words featuring specific soft and high-pitched consonants like 's,' 'f,' 'th,' or 't.'

While high-frequency hearing loss is frequently linked to age-related hearing decline, it can affect people of all age groups. People who suffer from it may even find that everyday conversations are muffled, particularly in noisy environments, leaving those afflicted with a sensation of hearing sounds but struggling to decipher speech effectively.

High-frequency hearing loss often worsens over time, making it increasingly challenging to manage as it progresses, especially when left untreated. Unfortunately, while it is generally irreversible, it can be prevented, primarily by protecting your ears from loud noises over 85 decibels. In addition, hearing aids have been proven effective in addressing this particular hearing loss.

Symptoms of High-Frequency Hearing Loss

High-frequency hearing loss presents a range of symptoms that can significantly impact an individual's auditory experience and overall quality of life. While the severity of symptoms may vary, the common thread among those affected is a reduced ability to perceive sounds between the 2,000 to 8,000 Hertz range. Here are some of the key symptoms associated with high-frequency hearing loss:

  • Difficulty Hearing High-Pitched Voices
    One of the hallmark symptoms of high-frequency hearing loss is the struggle to hear high-pitched voices clearly, which often includes children's voices and the voices of women. 
  • Difficulty Distinguishing Certain Consonants
    High-frequency hearing loss can lead to difficulty distinguishing or understanding words that start or end in soft consonants and are higher in pitch, such as 's,' 'f,' 'th,' or 't.' 

  • Impaired Perception of Environmental Sounds
    People with high-frequency hearing loss often have trouble hearing sounds that are important for situational awareness, such as the chirping of birds, the beeping of alarms, or the rustling of leaves in the wind. These sounds, which contribute to our overall understanding of the world around us, may become faint or indiscernible.

  • Challenges in Noisy Environments
    Background noise, which is already a common challenge for those with hearing loss, becomes even more problematic for individuals with high-frequency hearing loss. Normal conversations can become muffled and difficult to understand in noisy environments with competing noises, like large groups or lots of background noise.

  • Worsening Over Time
    High-frequency hearing loss often progresses and worsens over time. As the condition advances, it becomes increasingly challenging to manage and adapt to, particularly if left untreated.

Recognizing these symptoms is important for early intervention and management of high-frequency hearing loss. Seeking professional guidance and exploring appropriate treatments, such as hearing aids, can be an enormous help when it comes to coping with this hearing challenge.

Causes of High-Frequency Hearing Loss

High-frequency hearing loss occurs when the delicate hair-like sensory hearing cells in your inner ear (cochlea) suffer damage. These tiny hair cells, called stereocilia, translate the sounds your ears capture into electrical impulses, which your brain interprets as identifiable sounds.

  • Age-Related Hearing Loss (Presbycusis): The natural aging process is the most common cause of high-frequency hearing loss. As people grow older, the delicate hair cells in the inner ear responsible for detecting high-frequency sounds can become damaged or deteriorate, leading to a gradual decline in hearing sensitivity.

  • Noise-Induced Hearing Loss: Exposure to loud noises, either over a short duration or prolonged periods, can damage the hair cells in the inner ear, especially those responsible for detecting high-pitched sounds. This type of hearing loss often occurs in individuals who are exposed to constant noise over 85 decibels, like those who work in noisy environments, attend loud concerts, or use personal listening devices at high volumes. It can also occur from a single, one-time exposure to something like an explosion or gunshot.

  • Medications: Certain medications, referred to as ototoxic drugs, can have harmful effects on the inner ear, leading to high-frequency hearing loss. These medications include some antibiotics, chemotherapy drugs, and certain diuretics, among others. While medications are prescribed for their established benefits, they may have side effects you should be aware of before taking. If you’re going to be taking a medication with a risk of ototoxicity, it is a good idea to see an audiologist first.

  • Ear Infections: Chronic or recurrent ear infections in children, particularly in the middle ear, can lead to high-frequency hearing loss if left untreated.

  • Genetic Factors: In some cases, genetic predisposition plays a role in high-frequency hearing loss. Individuals with a family history of hearing impairment may be at a higher risk of developing this condition.

High-Frequency Hearing Loss Prevention

Although some risk factors, such as genetics or certain medical conditions, are beyond our control, there are steps you can take to prevent high-frequency hearing loss. These include:

  • Noise Management
    Noise-induced hearing loss is a leading cause of high-frequency hearing impairment. To safeguard your hearing, minimize exposure to loud noises. This includes wearing hearing protection in noisy workplaces, using earplugs during activities like concerts, and keeping the volume at a safe level while using headphones or earbuds.

  • Hearing Protection
    In professions or hobbies with prolonged exposure to noisy environments, wearing hearing protection designed for the specific noise level is crucial.

  • Regular Hearing Tests
    Routine hearing check-ups can detect any early signs of high-frequency hearing loss. Early detection enables the ability for timely intervention and preventive measures, which can help manage the condition effectively and reduce further damage.

Remember that early intervention and protective habits are essential for preserving your hearing abilities and ensuring a higher quality of life.

Diagnosis and Treatment of High-Frequency Hearing Loss

There are several ways high-frequency hearing loss can be diagnosed and treated. The most common approach is to receive a hearing test performed by a licensed healthcare provider (HCP) . During this evaluation, the HCP will guide you through a series of tone presentations, asking you to identify the ones you hear. They will also play sounds in various environments, including tranquil settings and bustling locales, to assess your hearing abilities in different conditions. In some cases, they may also use an audiometer, a machine that emits sound waves into your ear and measures how well your ear responds to the sound.

Based on the results of these tests, the audiologist can diagnose the extent and specific characteristics of the high-frequency hearing loss, determining its severity, configuration, and whether it's unilateral (affecting one ear) or bilateral (affecting both ears).

Treatment plans for high-frequency hearing loss are tailored to the individual's diagnosis and specific needs, meaning there’s no one-size-fits-all solution. Some common treatment options include:

  • Hearing Aids
    Hearing aids are a standard treatment for all types of hearing loss, but the best type usually depends on the type of hearing loss and symptoms. For high-frequency hearing loss, in-the-ear (ITE), in-the-canal (ITC), and completely-in-canal (CIC) hearing aids with frequency-lowering or frequency compression technology are commonly recommended.

  • Assistive Listening Devices (ALDs)
    ALDs, such as hand-held amplifiers with microphones, bring the sounds you want to hear closer to your ears, help capture sound effectively, and can also filter out some background noise. There are ALDs designed for large facilities and noisy environments and ones that work better for one-on-one conversations.

  • Communication Strategies
    HCPs often provide communication strategies, like lip reading, sign language, or written notes, to help individuals with high-frequency hearing loss improve their understanding of speech and navigate challenging listening environments.

By undergoing a thorough diagnosis and implementing appropriate treatment strategies, individuals with high-frequency hearing loss can experience improved hearing, enhanced quality of life, and better communication abilities. Early intervention and a proactive approach to hearing health are key to effectively managing this condition.
