Hearing Conservation Program
Ways to reduce exposure include these (name 2)
Repair or change machinery
Isolate worker from machinery
Limit time exposure to noise
Ear protection
Single intense exposure may cause HL by mechanically damaging these
organ of corti or cochlear membranes
If you are listening to something at work at 100dBA, what length would require a hearing protection program
2 hours
PTA should be within this range of the SRT
10db
This test involves gradually introducing background noise below recorded response threshold as patient reads aloud
Lombard test
The objective of a hearing conservation program is this
to reduce the risk of developing a permanent NIHL
This may differentiate between NIHL, presbycusis, and ototoxicity
pattern of loss
A standard rock concert level is this
125 db
Someone faking loss will have normal results on these
ABR/OAE
In this test, the client is played back their own speech at a delay that would cause them to stutter
Lee's speech delay test
The three-foot rule means this
If you have to shout at an arms length, it is too loud!
This percent of children are estimated to experience NIHL
15%
A permanent threshold shift is caused by this kind of exposure
chronic
If tests suggest significant loss, these should be absent
acoustic reflexes
What kind of test does hong NOT recommend
startle test
The purpose of training and education is this
to take positive action to prevent NIHL
OHC damage from chronic loud noise due to this
oxygen radical formation
a temporary threshold shift resolves within this amount of time
24 hours
You should be suspicious if a patient hesitates, shifts pure tone thresholds, or does this
expresses confusion
In the Stenger test, for real HL this should happen
the tone should be heard in the better ear
You should maintain hearing assessments for this length of time
the entire period of employment PLUS 5 years
These are three features characteristic of NIHL
SNHL (mostly bilateral)
High-pitched tinnitus
4k notch
People in these careers are at a higher risk for NIHL
Factory workers, those who operate heavy machinery & military
True or false: it is often unrecognized by the client
In the Stenger test, fakers will say this
that they don't hear anything
