used

 

in

 

measuring

 

the

 

real

 

ear

 

acoustical

 

characteristics

 

of

 

hearing

 

instruments

 

in

situ.

 

The

 

device

 

performs

 

measurements

 

of

 

real

 

ear

 

acoustical

 

characteristics

 

of

 

a

 

hearing

 

instrument

  

on

 

a

 

given

 

human

 

ear,

 

and

 

does

 

comply

Statement:

  

 

The

 

hearing

 

aid

 

analyzer

 

is

 

intended

 

to

 

be

 

used

 

for

 

the

 

purposes

 

of

 

correctly

 

configuring

 

and

 

prescribing

 

the

 

audible

 

sound

 

levels

 

from

 

a

 

hearing

 

device/aid.

 

It

 

is

 

intended

 

to

 

measure

 

the

 

internal

 

effect

 

of

 

such

 

device

 

using

 

small

 

and

 

thin

 

probe

 

microphones

 

which

 

can

 

be

 

placed

 

in

 

the

 

patients’

 

ear

 

canal

 

to

 

allow

 

the

 

clinician

 

to

 

objectively

 

quantify

 

the

 

benefit

 

and

 

effect

 

the

 

device

 

has

 

on

 

the

 

patients

 

hearing.

 

These

 

measures

 

are

 

useful

 

in

 

the

 

fitting

 

and

 

prescription

 

of

 

acoustic

 

hearing

 

aids

 

in

 

correspondence

 

with

 

the

 

information

 

acquired

 

during

hearing

 

assessment.
