4
Q

a glass enclosure designed to regulate the flow of electric current.

A

vacuum tube

5
Q

an electronic device with low power consumption, and small space requirements, that amplified electric current through the use of semiconducting properties of an element such as silicon.

A

transistor

6
Q

an inseparable unification of several transistors on a small piece of silicon maintaining an electrical isolation of hte circuit components.

A

integrated circuit

7
Q

an amplification system in which the electrical signal is analogous to the input acoustical signal in frequency, intensity, and temporal patterns

A

analog hearing aid

8
Q

an amplification system in which the input signal is stored, as by a computer, as sets of binary digits that represent frequency, intensity, and temporal patterns of the input acoustical signal.

A

Digital hearing aid

9
Q

in a hearing aid, a method of limiting the amplification of louder sounds relative to weaker sounds.

A

compressions

10
Q

properties of hearing aids as defined by the hearing aid industry. conference, an organization of hearing aid manufacturers that provides standardization of measurement and reporting on hearing aid performance data.

A

electroacoustic characteristics

11
Q

The maximum ower out put of a hearing aid. The highest sound-pressure level to leave the receiver of a hearing aid, regardless of the input level.

A

output sound-pressure level

12
Q

in a hearing aid, the frequence range of amplification, expressed in Hz, from the lowest to the highest sound amplified

A

frequency response

13
Q

in a hearing aid, the result of an inexact copy of the input signal by the output signal. distortion is usually caused by the microphone, speaker, and/or amplifier.

A

Distortion

14
Q

The whistling sounds that is created when the signal leaving the receiver on the hearing aid leaks back into the microphone and is reamplified.

A

acoustic feedback

15
Q

allows ear canal to be more open allowing sounds to become more natural

A

open-fit hearing aid

16
Q

speaker more power

limitation: ear wax will get in the receiver

18
Q

A device that delivers amplified vibratory energy to the surface of the skin by special transducers; designed for patients whose losses are so severe that they receive no benefit from traditional hearing aids.

A

vibrotactile

19
Q

A coil and series of electrodes surgically placed in the mastoid and inner ear. It is designed to provide sound to a patient with a profound loss through a processor and external coil.

A

cochlear implant
