Type of Hearing Loss: Sensorineural hearing loss caused by damage to the cochlea or auditory nerve due to medications from chemotherapy.
Symptoms: Bilateral high-frequency hearing loss, tinnitus and/or speech perception difficulty
Treatment: Hearing aids or assistive devices

# data[].attributes.body
Type of Hearing Loss: Conductive. The eustachian tube cannot open and close. Which causes the middle space to suck the fluid from the surrounding tissue, builds up in the middle ear space, and impedes the movement of the ossicles and eardrum
Symptoms: Fluid buildup, aural fullness, ear pain, mild hearing loss
Treatment: Claritin, antibiotics, pressure equalization tubes if frequent

# data[].attributes.body
Type of Hearing Loss: Sensorineural. The Cochlea is underdeveloped, which increases the risk of hearing loss and meningitis.
Symptoms: Sensorineural hearing loss, meningitis risk
Treatment: Procedure to reduce meningitis risk

# data[].attributes.body
Type of Hearing Loss: Sensorineural. Genetic mutation affects potassium recycling in the organ of Corti, damaging inner ear function.
Symptoms: Mild to profound hearing loss at birth or early childhood
Treatment: Genetic testing

# data[].attributes.body
Type of Hearing Loss: Sensorineural. Exposure to loud sounds damages the inner ear hair cells, especially at high frequencies. It can be temporary, which means hair cells recover, and it is reversible. Or it can be Permanent which means hair cells are destroyed and it is irreversible.
Symptoms: Tinnitus; hearing loss in high frequencies
Treatment: Prevention, hearing aids

Audiogram of familiar sounds and speech banana

# data[].attributes.body
The speech banana is an area on the audiogram that indicates the frequency and decibel level of the majority of speech sounds. If someone's hearing thresholds falls outside this area they may miss key speech sounds

# data[].attributes.body
This chart shows how different levels of hearing loss can affect how someone hears and communicates

# data[].attributes.body
Both air conduction and bone conduction thresholds are abnormal

Air bone gaps present

Combination both conductive and sensorineural components

Speech recognition score could be depressed

Tympanogram usually abnormal

Otoacoustic emissions usually absent

# data[].attributes.body
Conductive Hearing Loss: Conductive hearing loss happens in the outer or middle ear and usually makes sounds seem softer.

Sensorineural Hearing Loss: Sensorineural hearing loss is usually caused by damage in the inner ear or hearing nerve and makes sounds quieter.

Mixed Hearing Loss: Mixed hearing loss is a combination of conductive and sensorineural loss whcih affects both loudness and clarity of sounds.

Battery or Battery Contact Issues

The battery might be dead, inserted incorrectly, or not making proper contact.

Try replacing the battery and cleaning the battery compartment.

Blocked Tubing

Earwax or moisture in the tubing can stop sound from getting through.

Use an air blower or wax loop to clean it out.

Blocked Tone Hook

If the tone hook (on BTE aids) is clogged, sound won’t pass through.

Clean or replace if needed.

Microphone Blockage or Damage

A clogged or damaged mic may cause weak or no input.

Clean the mic area with a brush or replace the mic cover.

Microphone
▸ Picks up sound from the environment and sends it into the hearing aid.

Amplifier
▸ Increases the volume of the sound so it’s easier to hear.

Receiver (Speaker)
▸ Sends the amplified sound into your ear.

Battery
▸ Powers the hearing aid

Earmold
▸ Custom part that fits in the ear and helps deliver sound clearly.

Tubing
▸ Connects the hearing aid to the earmold and carries sound into the ear.

Technology:

BTE: Sits behind the ear and for all loss levels.

ITE: Custom in the outer ear is usually good for mild to severe loss.

IIC: Tiny and hidden deep in the canal, usually it is best for mild to moderate loss.

RIC: Small behind-the-ear with a wire to the canal for mild to severe loss.

Features:

BrainHearing which supports, deep neural network processing, wind noise management

External Components:

Microphone: The microphone captures sound waves received.

Sound processor: Converts those sound waves into signals.

Transmitter coil: Sends electrical signals across the skin to the internal components.

Magnet: Makes sure the components stay in place.

Internal Components:

Receiver coil: Receives electrical signals externally.

Electrode array: A series of electrodes implanted into the cochlea which stimulate the auditory nerve.

Implant body: It's where the receiver coil and electrode array is.

Make sure the batteries are fresh or fully charged

Make sure the processor turned on

Try turning the processor off and back on.

Check the visual display or indicator lights on the processor.

Make sure the processor is set to the correct program and volume settings.

Confirm that all cables are connected properly and inspect for any twisted, frayed, or broken cords.

Use monitor earphones or a listening check device to verify microphone function.

If the child wears bilateral processors, try using the other cable or battery pack to troubleshoot.

Communication is key—keep caregivers and the audiologist informed to work through issues together.

The story of a deaf girl's connection to a whale whose song can't be heard by his species, and the journey she takes to help him.

From fixing the class computer to repairing old radios, twelve-year-old Iris is a tech genius. But she's the only deaf person in her school, so people often treat her like she's not very smart. If you've ever felt like no one was listening to you, then you know how hard that can be.

When she learns about Blue 55, a real whale who is unable to speak to other whales, Iris understands how he must feel. Then she has an idea: she should invent a way to "sing" to him! But he's three thousand miles away. How will she play her song for him?
