1. The intensity at which an individual prefers to listen to sound is commonly refered to as _____________.

Speech recognition threshold

Dynamic range

Most comfortable loudness level

Word discrimination

2. _______ is the perceived intensity of sound.

Pitch

Loudness

Intensity

Frequency

PITCH - the subjective auditory sensation that correlates to the frequency of a sound.
LOUDNESS - the subjective auditory sensation that correlates to intensity
INTENSITY - a quantity expressing the amount of sound such as sound pressure level, power or amplitude
FREQUENCY - the number of completed repitions of a waveform that occurs in a period of time (ex. cycles per second of Hz)

Explanation

PITCH - the subjective auditory sensation that correlates to the frequency of a sound.
LOUDNESS - the subjective auditory sensation that correlates to intensity
INTENSITY - a quantity expressing the amount of sound such as sound pressure level, power or amplitude

3. The process by which sound is conducted to the inner ear through the air in the ear canal and via the ossicles in the middle ear is called ________________.

Acoustics

Bone conduction

Air conduction

Audiometer

Air conduction is the process by which sound travels to the inner ear by going through the air in the ear canal then through the middle ear via the ossicles (malleus, incus & stapes).

Air conduction is the process by which sound travels to the inner ear by going through the air in the ear canal then through the middle ear via the ossicles (malleus, incus & stapes).

4. Which tuning fork test is most useful when a unilateral hearing loss is present?

Weber

Rinne

Stenger

Schwabach

The Weber, Rinne and Schwabach are all tuning fork tests.
The Stenger is not a tuning fork test, it employs the use of pure tones. The Stenger is a test to help determine whether a nonorganicor functional hearing loss is indicated.

5. The range of hearing between when a person first hears sound and the point that sound is uncomfortably loud is called ___________.

Most comfortable loudness

Recruitment

Tuning curve

Dynamic range

The dynamic range is the difference between the threshold of hearing and the threshold of pain.

Explanation

The dynamic range is the difference between the threshold of hearing and the threshold of pain.

6. An abnormal phenomenon of loudnes sensitivity is called _______________.

Recruitment

Dynamic range

Acoustics

Loudness discomfort level

recruitment is an abnormal loudness sensitivity which is generally regarded as a soft sign for a retrocochlear lesion.

Explanation

recruitment is an abnormal loudness sensitivity which is generally regarded as a soft sign for a retrocochlear lesion.

7. In which test is the stem of a vibrating tuning fork placed first on the temporal bone and then again near the ear the determine the presence of a sensorineural hearing loss?

Rinne

Bing

Weber

Stenger
