Audiometry Flashcards
A dial on the audiometer to control the decibels of output is called
An attenuator dial
Audiometric zero for pure tone is higher than the standard reference level by about
Differs at each frequency
ANSI stands for
American National Standards Institute
The audiometer is designed so that zero on the attenuator dial
Represents the level of normal hearing for that frequency
By air conduction, sound energy changes forms in which of the following manners
Acoustic, mechanical, hydraulic, electrical, chemical energy
The normal ear responds to a range of frequencies from
20-20,000Hz
Sounds waves, during bone conduction, transmit from the
Skull to cochlea
What is a phon
A unit of measurement when comparing the loudness of one frequency to another frequency
Routine hearing testing should be performed
In a sound controlled environment
Audiometric zero is
0 dB HL
0 dB Hearing level
The level where normal ears can hear at every frequency
