Q

What is the schwa Bach

A

Tuning fork on the table then on patients here let Dr. know when they can hear it but up to the doctors here and they can hear they have conductive hearing loss

23
Q

What is air conduction

A

Ability to be able to hear any given some through the normal hearing pathway

24
Q

What is bone conduction

A

Bypassing little going directly to enter year to get response of cochlea also to see if they have conductive hearing loss

non-organic
mixed

26
Q

What is when sound molecules pushed together

A

Compression

27
Q

What happens when the molecules spread apart

A

Rare fraction

28
Q

What is amplitude

A

The extent of the vibratory movement of mass from its position of rest that point farthest from the position of rest

29
Q

What is the longitudinal wave

A

Cycles occur parallel can be same or opposite

Complex

30
Q

What is a sine wave

A

Smooth wave that repeats cycles pure tones and tones that are only one pitch

31
Q

What is frequency

A

The number of complete ossicles of a vibrating body per unit of time.

32
Q

What is intensity

A

The amount of sound energy per unit of area

33
Q

What is the lowest sound you can hear

A

Fundamental frequency

34
Q

What is harmonics

A

While number multiples of fundamental frequency

35
Q

What is formance frequency

A

Concentration of acoustic energy around particular frequency in speech wave

36
Q

What the pressure goes up what happens to the loudness

A

It goes up

37
Q

What is the first step in seeing a patient

A

Case history

38
Q

What are s the threshold

A

Softest level which a patient can hear 50% of the time

39
Q

What is localization

A

Figuring out where the sound is coming from

40
Q

What are the three types of head phones

A

Insert ear
Supra aural
Bone ossilator

41
Q

When you can hear what does the audiologist do

A

Turn down by 10 dB

42
Q

When you cant hear what does the audiologist do

A

Turn up 5db

43
Q

What is the air bone gap

A

The amount by which the air conduction threshold of a patient exceeds the bone conduction thresh hold at any frequency in the same ear

44
Q

What happens when the normal ears and those with sensory neural impairments are covered by earphones or occluded by other devices, there is an increase in the intensity of a sounds delivered by a bone conduction vibrator to the cochlea. Changes in osseotympanic bone conduction.

A

Occlusion effect

45
Q

What bone is the ossilator

A

Mastoid

46
