In general, mold modifications Venting affects lows, damping the midrange and horn effects
are as follows: boost highs.
Basic verification involves: checking MCL and UCL in quiet and noise.
Sound field is a controlled environment
The configuration and height of A high Type A tells us to decrease the output by 2-3 dB
the tympanogram can be a
factor in deciding the proper
matrix for the fitting of a hearing
aid:
You cannot use feedback checking the telephone coil
checks when
Verification procedures: Check the accuracy of your fitting.
The problems produced by greater for the lower frequencies than the higher frequencies
excessive ambient noise are
The decibel is a ratio between two intensities
REUR measurement are taken in an open human ear canal
When a hearing aid is dead, you turning on the instrument telecoil
can check the receiver and
microphone function by:
The dividing line between the tympanic membrane
external and middle ear is the
, The cochlea, acting as a Place Theory
frequency analyzer, distributes
acoustic stimuli to places along
the basilar membrane according
to frequency. This forms the
basis of a hypothesis called the:
An organic disorder is when The hearing mechanism, the neural pathways and the brain.
there is damage to:
The speed of sound in air, in feet 1100

The most comfortable level is: About 45 dB HL or 65 dB SPL for normal ears
Any complex sound can be Fourier Spectral analysis
broken down into individual
