Who are the chief providers of audiologic rehabilitation?

Audiologists

Are hearing aids and assistive listening devices (ALDs) the same thing?

No, they are different devices.

True or False: Bone conduction hearing aids can be used for atresia.

True

What is atresia?

The absence or closure of the external ear canal.

What is anotia?

The absence of the external ear (pinna).

What hearing aid component picks up non-acoustic signals?

T-coil (telecoil)

What are non-acoustic signals?

Signals that are not sound waves, such as electromagnetic signals.

What does a T-coil do?

Picks up electromagnetic signals from compatible systems instead of using the hearing aid's microphone.

Which hearing aids typically do not have T-coils?

CIC hearing aids because they are very small.

What type of hearing aid can accommodate the widest range of hearing losses?

BTE (behind-the-ear) hearing aids

Why are BTE hearing aids commonly used for children?

They accommodate a wide range of hearing losses and can connect to classroom listening systems.

What is a RIC hearing aid?

Receiver-in-canal hearing aid. The speaker is inside the ear canal and connects to the hearing aid with a thin wire.

What is a BTE hearing aid?

Behind-the-ear hearing aid. The main components sit behind the ear, and sound travels through a tube into the ear.

What is the main difference between BTE and RIC hearing aids?

BTE hearing aids typically use a tube to deliver sound, while RIC hearing aids use a wire connected to a speaker in the ear canal.

Which hearing aids are custom-made?

CIC, ITE, and ITC hearing aids

What does CIC stand for?

Completely-in-canal

What does ITE stand for?

In-the-ear

What does ITC stand for?

In-the-canal

What is dynamic range?

The range between the softest sound a person can hear and the loudest sound they can comfortably tolerate.

What is a CROS hearing aid?

A hearing system that picks up sound from the poorer or unaidable ear and sends it to the better ear.

How does a CROS hearing aid work?

A microphone on the poorer ear picks up sound and transmits it to a receiver on the better ear.

Do CROS hearing aids restore hearing in the deaf ear?

No, they send sound to the better ear.

What is binaural amplification?

Using two hearing aids, one in each ear.

What are two benefits of binaural amplification?

Better sound localization and improved speech understanding in background noise.

What is sound localization?

The ability to identify where a sound is coming from.

True or False: Binaural hearing does not help with sound localization.

False. Binaural hearing helps with localization.

Do BAHA and CROS hearing aids restore normal sound localization?

No, they do not restore true binaural hearing.

What does BAHA stand for?

Bone-anchored hearing aid

How does a BAHA work?

It sends sound vibrations through the skull bone to stimulate the cochlea.

Does a person need a functioning cochlea to benefit from a BAHA?

Yes, at least one cochlea must have enough function to detect the vibrations.

True or False: Audiologists can modify custom earmolds to change how sound reaches the ear.

True

What are the purposes of an earmold?

To connect the hearing aid to the ear, help prevent feedback, and modify sound frequencies reaching the ear canal.

Which is NOT a primary purpose of an earmold?

Dampening wind noise in the ear canal

Why is reducing wind noise not a primary purpose of an earmold?

Because wind noise is mainly picked up by the hearing aid's microphone.

What is acoustic feedback in hearing aids?

A whistling sound that occurs when amplified sound escapes and is picked up again by the microphone.

Who generally benefits more from cochlear implants?

Children who receive implants early, especially during important periods of language development.

Why is early cochlear implantation important?

It provides earlier access to sound during critical periods of auditory and language development.

True or False: Some deaf individuals are not good candidates for cochlear implants.

True

Why might someone not be a good candidate for a cochlear implant?

They may have an absent or nonfunctional auditory nerve, or a long period of auditory deprivation that limits expected benefits.

True or False: The longer someone has had severe hearing loss, the better their cochlear implant prognosis.

False

How does a longer duration of severe hearing loss affect cochlear implant outcomes?

A longer period without auditory stimulation can reduce expected benefits, although outcomes vary.

When is cochlear implant mapping typically performed?

After surgery, commonly around 2-6 weeks later, depending on the clinic and device.

What is cochlear implant mapping?

Programming and adjusting the implant to provide appropriate electrical stimulation for hearing.

What is an FM system?

An assistive listening system that transmits a speaker's voice directly to a listener's hearing device.

What is the main benefit of an FM system?

It improves the signal-to-noise ratio, making speech easier to understand in background noise.

What is the signal-to-noise ratio (SNR)?

The difference between the level of the desired sound, such as speech, and the level of background noise.

How are FM systems used in classrooms?

The teacher wears a microphone that sends their voice directly to students' compatible hearing devices.

Do FM systems completely eliminate background noise?

No, they improve the clarity of the teacher's voice relative to background noise.

True or False: Sensorineural hearing loss must have an air-bone gap of at least 15 dB.

False

What is an air-bone gap?

The difference between air conduction and bone conduction hearing thresholds.

What does bone conduction testing primarily assess?

The function of the cochlea and auditory pathways while bypassing the outer and middle ear.

What does an air-bone gap indicate?

A conductive component of hearing loss.

Is there an air-bone gap in sensorineural hearing loss?

Typically no significant air-bone gap.

Is there an air-bone gap in conductive hearing loss?

Yes

Is there an air-bone gap in mixed hearing loss?

Yes, because mixed hearing loss includes a conductive component.

What is sensorineural hearing loss?

Hearing loss caused by damage or dysfunction in the inner ear or auditory nerve.

What is conductive hearing loss?

Hearing loss caused by a problem in the outer or middle ear that prevents sound from traveling efficiently to the inner ear.

What is mixed hearing loss?

A combination of conductive and sensorineural hearing loss.

Why might someone with sensorineural hearing loss have difficulty understanding speech?

Because the damage can affect both hearing sensitivity and speech clarity.

True or False: A cochlear implant can help some people with single-sided deafness regain binaural hearing.

True, although the amount of improvement in localization varies.
