Gene Therapy Breakthrough: Restoring Hearing in Children Born Deaf

Gene Therapy Breakthrough: Restoring Hearing in Children Born Deaf

In a remarkable medical advancement, five children who were born completely deaf due to a genetic mutation have regained their ability to hear after undergoing innovative gene therapy treatment. This groundbreaking development offers new hope for individuals with inherited deafness and showcases the potential of gene therapy in treating genetic disorders.

The Treatment

The gene therapy approach targeted a specific form of inherited deafness caused by mutations in the OTOF gene, which is responsible for producing the otoferlin protein. This protein plays a crucial role in transmitting signals from the ear to the brain [1] [2].

The treatment involved:

  • Delivering a functional copy of the OTOF gene to the hair cells in the inner ear
  • Using a modified virus (AAV) as a vector to carry the gene
  • Injecting the gene therapy mixture into both ears of the children

The Participants and Results

The trial, conducted in China, included five children aged between 3 and 7 years old [1].

Key outcomes include:

  • Hearing restoration: All five children gained the ability to hear in both ears
  • Hearing levels: Approximately 50-60% of normal hearing levels were achieved six months after treatment
  • Speech recognition: The children can now hear voices at conversational volumes
  • Sound localization: Participants gained the ability to locate the source of sounds

Significance of the Study

This trial marks several important milestones in the field of gene therapy and audiology:

  1. Bilateral treatment: This is the first clinical trial to administer gene therapy to both ears, providing enhanced benefits compared to single-ear treatments [4].
  2. Overcoming gene size limitations: The researchers successfully addressed the challenge of the large OTOF gene by splitting it into two parts and using separate viral vectors [2].
  3. Potential for wider application: The success of this approach opens doors for treating other forms of genetic deafness and possibly other genetic disorders [1].

Looking Ahead

While these results are extremely promising, researchers emphasize the need for further studies and longer follow-up periods. The team plans to treat the other ear of children who previously received treatment in just one ear.

This breakthrough not only offers hope for individuals with DFNB9, the specific form of deafness targeted in this study, but also paves the way for developing treatments for other genetic causes of hearing loss. As research progresses, gene therapy may become a viable option for many of the millions of people worldwide affected by genetic hearing impairments.The success of this trial represents a significant step forward in medical science, demonstrating the power of gene therapy to address previously untreatable genetic conditions and potentially transform lives.

Hearing Aids: A Potential Solution for Slowing Cognitive Decline in At Risk Individuals

Hearing Aids: A Potential Solution for Slowing Cognitive Decline in At Risk Individuals

Quick Take

Wearing hearing aids may slow down cognitive decline by nearly 50% in three years for seniors at a higher risk of dementia.

Addressing hearing loss might be a promising approach to reduce dementia risks in susceptible groups.

In the face of rising dementia concerns, a recent revelation has stirred hope: individuals at a heightened risk who wore hearing aids experienced a significant reduction (almost 50%) in cognitive decline over a span of three years. With an aging global population, and increasing numbers grappling with cognitive impairments, the call for effective and affordable interventions has never been more pressing.

A correlation between hearing impairment and onset of dementia in the elderly has been noted by numerous studies. Moreover, there’s growing evidence to suggest that employing hearing aids as a remedial measure for hearing loss can potentially stall the progression of cognitive issues. However, a comprehensive, randomized trial to verify these claims was yet to be undertaken.

Dr. Frank Lin from Johns Hopkins University, supported by NIH, helmed such an investigation. The team brought on board almost 1,000 seniors, aged between 70 and 84, to examine the difference in cognitive decline rates over three years, contingent on the usage of hearing aids.

Participants, primarily with severe hearing loss, were sourced from two distinct cohorts. The first comprised 250 elderly individuals involved in a longstanding heart health study across four U.S locations. The latter group of 739 participants was freshly enrolled from neighboring communities of these sites. Intriguingly, those from the heart-health study displayed an escalated dementia risk, evidenced by advanced age and faster cognitive decline rates.

Participants were divided into two groups: one received hearing aids along with guidance on their usage, while the other was enrolled in a health education regime focusing on holistic aging. Both factions underwent bi-annual check-ins for enhanced training reinforcement.

Standardized cognitive function tests were administered annually for three years. The findings, shared in ‘The Lancet’ on July 17, 2023, revealed that individuals equipped with hearing aids observed marked enhancements in communication skills throughout the research. Predictably, the health education group didn’t report any improvements in auditory or communication abilities.

Although a broad analysis didn’t showcase significant cognitive function alterations between the two groups, a deeper dive into the heart-health study subgroup (with elevated dementia risks) painted a different picture. Here, the advantages of hearing aids were pronounced, with wearers witnessing an almost 50% drop in cognitive decline rates compared to their counterparts.

Dr. Lin emphasized the feasibility of addressing hearing issues in senior years, marking it as a pivotal strategy in dementia prevention. As the study marches forward, the team’s focus remains on tracing cognitive shifts over an extended period, alongside delving into brain imaging and social interaction data. This is aimed at getting a clearer picture of how safeguarding auditory health might shield our elderly from cognitive degradation.

Dr. Lin’s parting advice? “For holistic health and contentment, we urge seniors to periodically assess their hearing and ensure any issues are aptly addressed.”

New Medicare Rebates for Hearing Tests: Bridging the Gap in Hearing Care 

New Medicare Rebates for Hearing Tests: Bridging the Gap in Hearing Care 

Policy Shift Empowers Audiologists to Address Hearing Care Inequalities 

In a proactive move to tackle hearing care disparities prevalent in Australia, the government has initiated major adjustments to the Medicare Benefits Schedule (MBS) with a focus on audiology items. This bold move, kicking in from 1st March 2023, is borne from the Australian Government’s dedication to implementing the suggestions formulated by the MBS Review Taskforce. Let’s explore these critical advancements: 

Breaking New Ground in Hearing Care Accessibility 

Highlighted by Dr Moh Dadafarin, the Principal Audiologist at Ear and Hearing Australia, this policy transformation represents a significant step towards universal accessibility to hearing healthcare within Australia. This innovative approach is predicted to nurture stronger relationships between audiologists and GPs, ensuring a larger segment of the Australian population has access to premium services. Following the advice of the MBS Review Taskforce Clinical Committee from 14th December 2020, the Australian Government is setting a robust groundwork for a broader and more inclusive healthcare setting. 

Broadening Access to Medicare and Audiology Rebates for Hearing Services 

In the past, securing a Medicare rebate for hearing evaluations necessitated a referral from either an ENT specialist or a neurologist. The recent changes have considerably expanded the referral channels, making it possible to claim Medicare and audiology rebates for hearing services with just a reference from a GP. 

Although these rebates don’t cover the entire expense of the hearing tests, since the services are not bulk billed, they do alleviate the financial stress commonly associated with such assessments. A GP referral, listing the relevant MBS items, is essential for each session to qualify for the rebate. It is vital to note that availing services without a GP referral would mean relinquishing the Medicare and audiology rebate, which could significantly mitigate the cost of the consultation. 

Pioneering Affordable Hearing Care Solutions for Diverse Age Groups 

This renewed strategy enables pensioners and seniors to be proactive in attending to their hearing health, markedly lowering the out-of-pocket expenses. Consequently, it encourages quicker actions to address hearing issues, circumventing potential complications linked with untreated hearing problems. 

Furthermore, this move marks a significant step in presenting affordable and prompt hearing care solutions for children and their families. It creates a supportive space where children’s hearing difficulties can be handled without the familiar financial pressures that have been a barrier in the past.

What Causes Tinnitus: 8 factors that can trigger tinnitus

What Causes Tinnitus: 8 factors that can trigger tinnitus


Welcome to our comprehensive blog on tinnitus, where we will dive deep into the intricate factors that contribute to the development of this auditory phenomenon. As audiologists, our mission is to provide you with a thorough understanding of tinnitus causes, empowering you to make informed decisions about your hearing health. Let’s embark on this enlightening journey together!

Section 1: Excessive Noise Exposure

Excessive noise exposure is a leading cause of tinnitus. Prolonged exposure to loud sounds, such as machinery, concerts, or headphones set at high volumes, can damage the delicate structures of the inner ear. This damage can lead to sensorineural hearing loss and trigger the perception of tinnitus. To protect your hearing, it is essential to limit exposure to loud noises, use hearing protection in noisy environments, and take regular breaks from loud activities.

Section 2: Aging and Hearing Health

As we age, changes occur in the auditory system that can contribute to the development of tinnitus. Age-related hearing loss, or presbycusis, affects the sensitivity of the inner ear, particularly to high-frequency sounds. This age-related hearing loss can be accompanied by tinnitus, as the brain compensates for the reduced auditory input. Regular hearing evaluations and the use of hearing aids, when necessary, can help manage age-related hearing loss and potentially alleviate associated tinnitus symptoms.

Section 3: The Waxy Intruder: Earwax Buildup

Earwax, or cerumen, plays a protective role in the ear canal. However, excessive earwax buildup can lead to tinnitus. When earwax accumulates and becomes impacted, it can cause blockages that interfere with sound transmission. This can result in the perception of tinnitus. It is important to avoid inserting objects into the ear canal to remove earwax, as this can push the wax further and cause more harm. Instead, consult with a healthcare professional or audiologist who can safely remove the excess earwax and provide guidance on maintaining proper ear hygiene.

Section 4: Medications: Unwanted Side Effects

Certain medications can have side effects that include tinnitus. Nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, high doses of aspirin, and some chemotherapy drugs are known to potentially induce tinnitus. The exact mechanisms behind these medication-induced tinnitus cases are not fully understood. If you suspect that your medication is causing or worsening your tinnitus, it is important to consult with your healthcare provider. They can evaluate your medication regimen and explore alternative options if necessary.

Section 5: Beyond the Ringing: Underlying Medical Conditions

Tinnitus can be a symptom of various underlying medical conditions. Ménière’s disease, an inner ear disorder characterized by vertigo and hearing loss, is often accompanied by tinnitus. Otosclerosis, a condition where the bones of the middle ear harden, can also cause tinnitus. Temporomandibular joint (TMJ) disorders, affecting the jaw joint, and acoustic neuroma, a benign tumor on the nerve responsible for hearing, can both be associated with tinnitus. Proper diagnosis and treatment of these underlying conditions are essential to effectively manage tinnitus symptoms.

Section 6: Stress and Anxiety: A Symphonic Duo

Stress and anxiety can exacerbate tinnitus symptoms. While stress does not directly cause tinnitus, it can make the perception of tinnitus more bothersome and intrusive. The exact relationship between stress, anxiety, and tinnitus is complex and can vary from person to person. However, stress management techniques, such as relaxation exercises, mindfulness, and counseling, can help individuals cope with stress and reduce the impact it has on their tinnitus experience.

Section 7: Unveiling Trauma: Head and Neck Injuries

Head and neck injuries, such as concussions, whiplash, or direct trauma to the ear, can damage the auditory pathways and lead to tinnitus. The exact mechanisms through which these injuries cause tinnitus are still being studied. If you have experienced head or neck trauma and are experiencing tinnitus, seeking prompt medical attention is crucial. Comprehensive evaluations by audiologists or healthcare professionals specialized in ear and hearing disorders can help determine the extent of the injury and develop appropriate treatment plans to address both the underlying injury and the associated tinnitus symptoms.

Section 8: Nutrition and Lifestyle: Keys to Quieting Tinnitus

While there is no specific diet or lifestyle that can completely cure tinnitus, certain nutritional and lifestyle factors may play a role in managing tinnitus symptoms. Some individuals report that reducing their intake of caffeine, alcohol, and nicotine can help alleviate tinnitus. Additionally, adopting a healthy and balanced diet that includes essential nutrients like vitamins B12, magnesium, and zinc may support overall hearing health. It is important to note that these adjustments may have varying effects on different individuals, and consulting with a healthcare professional or audiologist is recommended to determine the most suitable approach for your specific situation.


By gaining a deeper understanding of the various causes of tinnitus, you are better equipped to address the specific factors contributing to your individual experience. Remember, our team of dedicated audiologists is here to provide expert evaluation, personalized treatment plans, and ongoing support on your tinnitus journey. We are committed to helping you find relief and regain a sense of harmony in your auditory experiences.

How Do Hearing Aids Work

How Do Hearing Aids Work

I. Introduction

Hearing loss is a common condition that affects millions of people worldwide, and can have a significant impact on a person’s quality of life. Fortunately, advances in technology have led to the development of hearing aids, which can help individuals with hearing loss improve their communication abilities and participate in daily activities.

Hearing aids are small electronic devices that are designed to amplify sound and improve the wearer’s ability to hear. They come in a range of styles and sizes, from behind-the-ear models to nearly invisible in-the-ear styles. The specific features and settings of a hearing aid may vary depending on the individual’s needs and preferences.

The history of hearing aids dates back several centuries, with various attempts to assist people with hearing loss. One of the earliest devices was the ear trumpet, which was made from materials like wood, animal horns, or seashells, and focused sound waves into the ear. Later, in the 19th century, the first electronic hearing aids were developed, which used carbon transmitters to amplify sound.

Today’s hearing aids are much more sophisticated and effective than their early counterparts. They are equipped with powerful processors, advanced noise reduction algorithms, and various features to improve the wearer’s listening experience. In the following sections, we’ll explore how hearing aids work in more detail and how they can benefit people with hearing loss.

II. Anatomy of a hearing aid

A hearing aid is made up of several key components that work together to amplify sound and enhance the wearer’s ability to hear. Here are the main parts of a hearing aid and how they work:

Microphone: This is the part of the hearing aid that picks up sound from the environment. The microphone converts sound waves into electrical signals, which are then processed by the hearing aid’s internal circuitry.

Processor: The processor is the “brain” of the hearing aid. It takes the electrical signals from the microphone and converts them into digital signals that can be amplified and manipulated to enhance sound quality.

Amplifier: The amplifier is responsible for increasing the volume of the sound signals that have been processed by the processor. It can amplify specific frequencies or adjust the overall volume of the sound, depending on the wearer’s needs.

Speaker: The speaker, also known as the receiver, is the part of the hearing aid that sends the amplified sound signals into the ear canal. The sound vibrations are converted back into sound waves that the wearer can hear.

All of these parts work together to create a customized listening experience for the wearer. The microphone picks up sound from the environment, which is processed by the internal circuitry, amplified by the amplifier, and then delivered to the ear through the speaker. The result is enhanced sound quality and improved hearing for individuals with hearing loss.

III. How sound is processed in a hearing aid

Modern hearing aids use digital signal processing (DSP) technology to analyze and enhance sound based on the wearer’s hearing needs. Here’s how it works:

Analog to digital conversion: The microphone picks up sound waves, which are then converted into digital signals that can be processed by the hearing aid’s internal circuitry.

Sound analysis: The digital signals are analyzed by the DSP chip, which identifies specific sound frequencies and adjusts them to meet the wearer’s hearing needs. This may involve amplifying certain frequencies or reducing background noise.

Sound enhancement: After the sound has been analyzed, the DSP chip applies advanced algorithms to enhance the sound quality. For example, it may use noise reduction technology to reduce unwanted background noise, or directional microphones to help the wearer focus on sounds coming from a specific direction.

Amplification: Once the sound has been analyzed and enhanced, it is amplified by the hearing aid’s

These processing steps can be customized based on the wearer’s specific hearing needs. For example, a hearing aid may be programmed to amplify certain frequencies that the wearer has difficulty hearing, or to adjust the overall volume of the sound. Additionally, many modern hearing aids include additional features such as wireless connectivity and automatic program switching, which can further improve the listening experience.

Overall, the digital signal processing technology used in modern hearing aids allows for a more customized and effective hearing experience for individuals with hearing loss.

IV. Types of hearing aids

There are several different types of hearing aids available on the market today, each with its own unique set of features and benefits. Here’s an overview of the most common types of hearing aids:

Behind-the-ear (BTE) hearing aids: BTE hearing aids sit behind the ear and are connected to an earpiece that fits inside the ear canal. They are often the largest and most visible type of hearing aid, but are also the most powerful and versatile.

In-the-ear (ITE) hearing aids: ITE hearing aids are custom-molded to fit inside the ear canal, making them more discreet than BTE models. However, they are generally less powerful and may not be suitable for more severe hearing loss.

In-the-canal (ITC) hearing aids: ITC hearing aids are similar to ITE models, but sit deeper inside the ear canal for even greater discretion. However, they may be more difficult to adjust and can be susceptible to earwax buildup.

Extended wear hearing aids: Extended wear hearing aids are a type of hearing device that can be worn continuously for several months at a time. These devices are designed to provide a discreet and convenient solution for individuals with hearing loss.

Each type of hearing aid has its own set of pros and cons, and the best type of hearing aid for you will depend on your specific hearing needs and lifestyle preferences. For example, if you have a more active lifestyle, you may prefer a BTE hearing aid with features like water resistance or noise reduction. If you want a more discreet option, an ITE, ITC or Extended wear hearing aid may be a better choice.

Additionally, many modern hearing aids offer additional features such as rechargeability and wireless connectivity, which can make them more convenient and user-friendly. When selecting a hearing aid, it’s important to work with a qualified audiologist or hearing healthcare professional who can help you choose the best option for your needs.

V. Features and settings of hearing aids

Modern hearing aids offer a wide range of features and settings designed to enhance the listening experience for individuals with hearing loss. Here’s an overview of some of the most common features found in hearing aids:
