Denser the medium - correct answer -the faster sound will travel,
sound travels fastest through steel
.0002 dynes per sq cm2 - correct answer -Faintest sound that can
be detected
6400Hz is the 5th octave of what frequency - correct answer -
400Hz
PTA should agree with SRT - correct answer -By +/- 10dB
Direct Contact Transmission - correct answer -requires close
association between infected and susceptible host Kissing,
sexual, etc

,indirect transmission - correct answer -When and infected hosts
touches a surface and another person comes into contact with the
infected surface
Droplet Contact Transmission - correct answer -Droplets of
mucus
Exit by coughing, exhaling, and sneezing
vehicle transmission - correct answer -When a contaminant is
ingested or there is exposure to contaminated substance via food,
water or bodily substance ex: Salmonella and e-coli
Airborne Transmission - correct answer -When droplets or dust
particles stay in the air for long periods of time
vectorborne transmission - correct answer -an animal contains
and transmits an infectious organism to humans
Disinfection - correct answer -kills, inhibits, or removes most
microbes from inanimate surfaces: towelettes, hospital grade
liquid sprays etch

, Sterilization - correct answer -The process that completely
destroys all microbial life, including spores. Used for critical
instruments like curettes and speculas
Type A tympanogram - correct answer -normal middle ear
function- if hearing loss is on the audiogram should be SNHL, No
air bone gaps, normal TPP, PMC, ECV
Type B tympanogram - correct answer -Flat. Fluid or perforation
or obstruction, Air bone gaps are typical there is something in the
middle ear space keeping the system from moving with pressure
change
Type As Tympanogram or A-Shallow - correct answer -Normal
middle-ear pressure, normal ear canal volume with reduced
tympanic membrane mobility (low compliance).
Middle-ear system with increased mass and high resistance.
Common in otosclerosis, cholesteatoma, tympanoesclerosis, and
ossicular fixation
