SPA 4032 Audiology Class #11: Audiologic Treatment Tools - Hearing Aids

These flashcards cover crucial vocabulary and concepts related to audiologic treatment tools, specifically hearing aids, as discussed in class.

Audiologic Treatment Goal

To limit communication disorders caused by hearing loss and maximize residual hearing before broader aural rehabilitation.

Hearing Aid Components

A hearing aid primarily consists of a microphone, amplifier, and receiver (loudspeaker).

Loudness Discomfort Level (LDL)

The level at which sound becomes uncomfortably loud, essential for setting maximum output levels for hearing aids.

Binaural Amplification

Using two hearing aids to improve hearing, particularly in noise, localization, and speech audibility.

Assistive Listening Devices

Devices used alongside hearing aids to improve communication access for individuals with hearing loss.

Types of Hearing Aids

Includes In-the-Ear (ITE), Behind-the-Ear (BTE), and Receiver-in-the-Canal (RIC) styles, each with distinct features.

Acoustic Coupling

The method by which sound from a hearing aid is effectively delivered to the ear, including closed and open fittings.

Prescriptive Algorithms

Formulas used to determine how much gain to deliver at different frequencies based on the patient's hearing profile.

Patient Factors in Hearing Aid Selection

Considerations including anatomy, dexterity, vision, and personal preferences that affect hearing aid fitting and selection.

Verification: Real Ear Measurements

Testing method used to ensure the hearing aid meets target outputs, measuring gain in real-ear conditions.
