Tinnitus – A Complete Guide on the Cause and Treatment

Tinnitus refers to one of the most common hearing impairments that prevails worldwide. According to Forbes, tinnitus afflicted around 75% of the global population at least once in their lives. Although it is preventable, understanding the symptoms and when to approach audiologists or hearing aid clinics is essential. In the following blog, we will provide you with an end-to-end overview of this hearing impairment, its types, symptoms, causes, and treatments so that you get the right help on time for healthy living.

What is Tinnitus?

Tinnitus refers to an auditory impairment where a person perceives a sound that does not come from external factors. The word originates from the Latin “tinnire” which means “to ring”. Most tinnitus-affected individuals perceive a ringing in their ears, but many also hear a buzz or roar.

This hearing impairment affects both adults and children. Although one can address it with the right treatment and medication, if this impairment lasts for more than 3 months audiologists consider it as chronic. Therefore, once you start facing the symptoms as mentioned in the following, you must consider consulting a reputed audiologist or hearing aid clinic.

What are the Symptoms of Tinnitus?

The symptoms of tinnitus widely differ from one person to another. However, the most common indication of this hearing impairment include:

  • Constant or irregular sound
  • Hear ringing, buzzing, humming, or other noises in the ears
  • Headache or pain in the ears in some cases
  • Variation in sound intensity or frequency
  • Sleep disturbances
  • Anxiety or emotional distress
  • Sensitivity to noise

What are the Different Types of Tinnitus?

Tinnitus comes in four different types including:

  • Subjective tinnitus: It refers to the most common type that results from a disorder in an auditory nerve or the inner ear.
  • Objective tinnitus: It refers to the auditory impairment where a person hears the sound of his/her muscle contraction or pulse. Jaw muscle movement, blood flow in the face/neck, muscle spasms around the middle ear, myoclonus twitching, and other vascular conditions can cause these sounds.
  • Pediatric tinnitus: It refers to hearing impairment due to vascular anomalies affecting ear structures. It commonly affects children.
  • Pulsatile tinnitus: Pulsatile or vascular tinnitus refers to the auditory impairment where an individual hears a sound synchronized with their pulse. Atherosclerosis, altered blood flow, or venous hum can cause this hearing impairment.

What is Tinnitus Caused By?

The primary causes of this hearing impairment include:

  • Abnormal bone growth in the ear (otosclerosis)
  • Age-related hearing issues
  • Blood vessel disorder
  • Consumption of antibiotics, antidepressants, NSAIDs (non-steroidal anti-inflammatory drugs) and other medicated drugs
  • Earwax blockages or ear infections
  • Eustachian tube dysfunction
  • Exposure to loud noises or noise induced hearing loss
  • Injuries to the brain or ear
  • Lupus, rheumatoid arthritis, or other auto-immune diseases.
  • Ménière’s disease
  • Non-cancerous tumor on the vestibular nerve known as vestibular schwannoma
  • Temporomandibular joint (TMJ) disorders, and more

How is Tinnitus Diagnosed?

Although audiologists detect it from the symptoms themselves, they perform physical examinations to understand the cause of this impairment. This helps them in following the right treatment method to address tinnitus. Some of these examinations include:

  • Audiological (hearing) examination: In a hearing examination, audiologists ask you to sit in a soundproof room and wear specific headphones. These headphones transmit specific sounds into each ear one by one. Based on your auditory perception and comparison with specific parameters, doctors identify the cause of the tinnitus.
  • Blood tests: Audiologists also recommend performing blood examinations to check for anemia, cardiovascular (heart) diseases, thyroid, and other health problems that could have triggered this hearing impairment.
  • Imaging tests: Audiologists may recommend undergoing CT or MRI scans to confirm the cause of this hearing impairment.
  • Movement examination: In this type of examination, audiologists ask you to move your arms, eyes, jaws, and neck. Based on the discomfort you experience in your ears during a particular movement, doctors identify the disorder that needs addressing.

How to Address Tinnitus?

Audiologists prescribe the following treatment to address this issue.

  • Removing earwax: If earwax caused this hearing impairment, then audiologists will suggest removing earwax medically.
  • Treating blood vessels in the ear: A poor blood vessel condition may trigger this hearing impairment. In such cases, doctors may recommend medication or surgery to treat the condition for addressing tinnitus.
  • Hearing aids: Doctors will suggest hearing aids if you get tinnitus due to age-related or noise induced hearing loss. These devices amplify noises to improve auditory perception and reduce tinnitus symptoms.
  • Administering in-ear noise generators: In-ear noise generators transmit white noise that provides relief to tinnitus. Doctors recommend these devices to individuals (especially elders) with incurable tinnitus.
  • Counseling: Audiologists may also recommend Cognitive Behavioral Therapy (CBT), Tinnitus Retraining Therapy (TRT), or other counseling forms to change the way you perceive this hearing impairment and reduce its effect over time.

When Should You Consult an Audiologist?

Although many individuals do not bother with this hearing impairment, you may consider consulting an audiologist if you:

  • Perceive ringing or other sounds in your ear for more than a week.
  • Experience dizziness or hearing loss due to this impairment.
  • Develop anxiety or depression due to this hearing impairment.
  • Start facing vertigo after this impairment affects you.


In conclusion, tinnitus is a widespread hearing impairment, affecting a significant portion of the global population. Understanding its symptoms, types, causes, and treatments is crucial for timely action and prevention of long-term consequences. Seeking help from audiologists and hearing aid clinics can help in effective management and improved quality of life.

The modern binaural process technology acts as a bridge between these two devices. This technology helps the pair of hearing aids to communicate wirelessly and replicate the brain’s ability to process information from both ears for an effective hearing experience.

4. Directional Technologies

Modern hearing devices integrate direction technologies to improve sound and speech clarity in noisy environments. This technology employs directional microphones and motion sensors to focus on sounds from a single direction and eliminate sounds from other directions. Hence, this technology improves the signal-to-noise ratio (SNR) and provides a better, comfortable hearing experience.

5. Environment Detection & Adjustment Automation

Many digital hearing aid come with automatic environment detection and adjustment technology. This technology enables the hearing device to scan the surrounding environment 10,000 times a second based on your movement. Furthermore, they automatically adjust the settings to deliver a clear and natural sound. Hence, with modern hearing aids you no longer have to fine-tune your settings manually again!

6. Noise Reduction & Speech Enhancement Technologies

Modern hearing devices provide noise-reduction technology. This technology uses advanced algorithms and sound processing techniques to detect and eliminate unwanted external noise. The reduction of irrelevant background noise helps to reduce ear strain in noisy surroundings and improve the hearing experience.

Digital hearing aids also use speech-enhancement technology to enhance speech intelligibility. This technology employs deep-learning algorithms to distinguish speech from external noises and ensure speech clarity.

7. Rechargeable Batteries

Digital hearing aids now come with cost-effective and environment-friendly rechargeable lithium-ion batteries. These batteries remove the hassle of replacing tiny batteries. Furthermore, modern hearing devices come with portable charging cases that keep these devices operating all day long.

8. Smart Applications

Modern hearing devices also provide separate applications that individuals can use to change device volume or program right from their mobile phones. These applications can be found in both the App Store (for iOS devices) and Play Store (for Android devices).

9. Telecoil (t-coil)

Telecoil or t-coil refers to a small coil of wire used in hearing aids. This wire picks up electromagnetic signals from compatible devices. Furthermore, it allows direct audio input from phones and public sound systems. Moreover, it reduces background noise and improves sound clarity for individuals suffering from hearing loss. This technology enables clearer communication in noisy environments and enhances the hearing experience for users.

10. Tinnitus Masking

Modern digital hearing aid integrated with tinnitus masking/management features can relieve individuals with ringing in the ears. These devices enable audiologists or hearing aid clinics to customize and deliver a soothing sound stimulus that helps manage and relieve tinnitus.


In the upcoming years, digital hearing aids will provide greater features and functionality to users due to advancements in technology. Not only will devices address common hearing issues like tinnitus but will improve the hearing experience for those with severe or permanent hearing impairment. However, before using any such technologically advanced hearing devices, individuals must consult with their audiologists or hearing aid clinics for the best experience.


Types of Hearing Aid: 10 Options to Choose From

Different types of hearing aids have risen in demand due to the astonishing number of people suffering from hearing loss. According to the latest report from WHO, around 430 million people, out of which 34 million are children, require medical support and hearing aids to address hearing loss. But will one solution fit every individual’s needs? That is quite unlikely.

Finding the perfect hearing aid depends upon several factors. The prime ones include hearing loss severity, shape/size of ears, and personal preferences. All these factors decide which type of hearing will suit you the best.

Primarily, there are ten types of hearing aid styles. Let us explore them in detail.

1. Behind the ear (BTE) devices

The first in the list of prime types of hearing aids is “behind the ear” (BTE) devices. BTE devices refer to hearing aid solutions that fit at the visible part of the ear outside your head (usually called the auricle). These devices comprise a case, a dome tip/earmold, and a tube. The tube connects the case with the dome tip or the earmold. The case houses a battery, controls, microphone(s), and loudspeaker/receiver.

Furthermore, BTE devices come in different sizes, ranging from small to larger, ultra-powerful devices. Although you can use these devices for any hearing loss severity, we recommend consulting a reputed hearing aid clinic for the right solution.

2. CROS/BiCROS devices

The second in the list of prime types of hearing aids is CROS/BiCROS devices. Contralateral Routing of Signal (CROS) and Bilateral microphones with Contralateral Routing of Signal (BiCROS) devices refer to solutions that transfer auditory information from one part of the head to another. Hearing aid clinics recommend CROS devices to people with hearing issues on one side and perfect hearing on the other side. BiCROS devices are effective for those having hearing loss on one side and moderate hearing on the other side.

Both these solutions come with a device and a microphone. Hearing aid clinics put the device on the side where you can listen normally and a microphone on the side with good or moderate hearing. The device transmits the information to the microphone. This transmission lets you hear clearly and localize sound from the affected side.

3. In the canal (ITC)

The third in the list of prime types of hearing aids is “in the canal” (ITC) solutions. These solutions fit deeply into ear canals compared to ITE devices. However, earwax can often clog the device’s speaker, and this can lead to hearing issues. Due to their small sizes, they comprise smaller batteries and are less visible. Despite its small size, ITC may be difficult to adjust and handle. This type of hearing aid helps people with less to moderate hearing loss.

4. In the ear (ITE)

The fourth in the list of prime types of hearing aids is “in the ear (ITE)” devices. ITE devices come in two main categories – full shell and half shell. The full shell ITE fits entirely in the outer ear’s bowl-shaped area. On the other hand, the half shell only covers the lower part of the bowl-shaped area. These solutions comprise larger batteries and directional microphones. Clinics recommend ITE devices for people having moderate to severe hearing issues.

5. Receiver in the ear (RITE)

The fifth in the list of prime types of hearing aids is “receiver in the ear (RITE)” devices. These hearing aid solutions are similar to “behind the ear” devices. However, unlike BTE, the speaker/receiver of this device is fitted in the ear canal instead of a shell. A soft tube called a dome connects the device to the ear. The dome does not seal the ear canal and lets the sound naturally flow in and out of the ear. These devices can help improve mild to severe hearing loss.

6. Receiver in the canal (RIC)

The last in the list of prime types of hearing aids is “receiver in the canal (RIC)” devices. RITE has a similar style to BTE. These devices have a directional microphone, speaker/receiver, and a wire. The wire connects the microphone to the speaker/receiver that fits in the ear canal. Furthermore, it comes with manual controls that offer greater control to the users.

Additional Types of Hearing Aids

Some additional types of hearing aids include:

  • Bone-anchored (BAHA) devices
  • Completely in the canal (or Mini CIC) devices
  • Invisible devices
  • Open fit devices


So those were the prime types of hearing aids at a glance. To select the right hearing aid for you or your loved ones, you must consult with an experienced hearing aid clinic. For more details and information on hearing aids, do not forget to follow our blog.
