Exam 1 Part 5 Flashcards
Point of intensity to activate compression; signal amplified to a lesser degree
Knee point
Ratio between input sound pressure level (SPL) change and output SPL change
Compression level
Part of a hearing aid where it converts electric signal back to acoustic energy; considered a small loudspeaker and deliverer of the speech signal
Receiver
Anchors the hearing aid, deliver sound from receiver to ear canal
Ear molds
Picks up telephone signal
t-coil,/telecoil
Adjusts amplification level
Volume control
Program and switch channels
Remote control
Box worn on torso or around neck, powerful and has larger controls
Body aid
Bypasses outer and middle ear, delivers sound via vibration through the mastoid
Bone conduction aid
Flexible style of hearing aid that is typically used for children, can be used with assistive listening devices, less feedback, easy to clean, fewer repaired, used for mild to profound hearing loss
Behind the ear
Hearing aid style with thin tubing that the receiver rests in the canal, less occlusion effect, used for mild to severe hearing loss and high frequency hearing loss
Receiver in canal
Hearing aid style with enhanced amplification on high frequencies, receiver placement allows need for gain, mild to severe hearing loss
In-the-ear
Style of hearing aid that fills less of concha than in the ear, enhanced amplification of high frequencies, receiver replacement allows less need for gain, mild to moderately severe hearing loss
In the canal
Style of hearing aid that is cosmetically appealing and easy to insert/remove, reduction of occlusion effect and feedback, sound localization improvement, elimination of wind noise, greater high frequency gain and enhanced telephone use, mild to moderate hearing loss
Completely in canal
Surgically implanted in mastoid, external processor attached with magnet or button, uses bone conduction that bypasses outer and middle ear, used for conductive or mixed hearing loss, atresia, stenosis, microtia, anotia, chronic infection, single sided deafness (SSD)
Bone anchored hearing aid/listening device
