Psychogenic Hearing loss

A

Hearing loss or impairment caused by a mental or emotional disorder or trauma and having no evidence of an organic cause.

74
Q

Pure Tone

A

Consists of only One Frequency

75
Q

Pure Tone Audiometry

A

is the key hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss.

76
Q

Quality & Timber

A

Determined by amount of Pure Tones and Relative Strength of each Pure Tone

77
Q

Quantinazation

A

is the process of converting a continuous range of values into a finite range of discreet values. This is a function of analog-to-digital converters, which create a series of digital values to represent the original analog signal.

78
Q

Small increase in sound intensity is perceived as a rapid increase in loudness. (Sensorineural loss)

79
Q

Reflection

A

Return of sound waves towrds thier source
